CLC | Card latency counter

The latency counter is a 24 bits wide counter, so a latency from 0 to 16777215 can be programmed. For capturing modules, the latency counter counts down from programmed number of latency samples before the capture memory address counter starts. As long as the latency counter has not counted down to zero, the memory address counter does not increment. This way, the actual start of the capturing can be delayed for a number of samples. For a the DIO in stimulus mode, the latency counter starts after the stimulus memory address counter has reached its end address. This allows DIO clock generation to continue even after the DIO is finished generating its programmed pattern, so the capturing device (WFD) receives enough clocks to capture the samples that are still in the pipeline.

related commands: CML, CSL

CMEMA | Set card memory address counter

The command directly writes the memory address counter of the stimulus or capturing memory. Prior to each measurement, this counter should be initiated with the address location from which the stimulus starts or from which the captured data is to be stored. Direct read and write from and to the module memory are done to the address pointed with the address counter. After a write or read action, the address counter increments automatically.

CMF | Card memory fill

The stimulus memory of the selected module is filled with one of the 10 signal items (0..9) One signal item holds one or more signal definitions, defined with the SIGNAL and SIGNAL_ADD command. Optionally an offset address can be specified. This defines the start address of the storage location in the stimulus memory. When needed, the digital codes written to the stimulus memory can be logically shifted with shift parameter p. For a left shift (least significant bits are loaded with 0) a negative shift value should be given. This feature can be used for (serial) DA converters that do not use the least significant bits of the applied data. Note: The DIO memory has a data mask option to add "static" bits to the stimulus data. Refer to the command descriptions for DIO_ANDMASK, or DIO_XORMASK.

For generating signals with an AWG module and high signal frequencies relative to the samplefrequency, please be aware of the DAC frequency response. An online sinc calculator can be found here.

example:

To store signalitem2 into card2 from memory address 400hex: 2CMF2,0x400

To store signalitem0 into the DIO (card0) from memory address 0hex but with a left shift of two bits: 0CMF0,0,-2

back to index

CML | Card measurement loop counter

During a measurement loop, the stimulus memory contents between the stimulus return-to and end address are output to the DUT. The number of times this stimulus is repeated while converted data is captured is defined by the Stimulus Measurement loop Counter setting in the generating module. In a capturing module, CML is normally set to only one loop. Note that the capture memory size is limited. When the number of results recorded in the capture memory exceeds the memory size, the capture memory address counter stops, and the capturing of data will be terminated. It is possible to define a number of settle loops (command CSL) before the actual measurement loops start.

CSELECT | Select Card

This command applies to: all modules installed in the ATX7006.

This command selects one of the Cards (modules). All other Card Setting commands operate on the selected Card only. Alternatively, the card can be selected by typing the card number in front of these card setting commands. This makes the CSELECT command needless. The module address is related with the backplane slot location used by the module. The DIO is always located in slot 0. The most right module slot has address 8.

CSIGNALD | Dump card signal

This command reads the signal from the module memory. n is the start address, o is the number of samples to dump. If the active module is analog, this command returns the actual voltage values that correspond with the stored hexadecimal values. The voltage value calculation is influenced by the actual range setting of the card. For a digital module, this command returns the contents of the memory in hexadecimal format. Optional parameter p can be used to shift a digital signal (positive value is right shift). This command can also be helpful to check the contents of a stimulus memory.

CSL | Card settle loop counter

During a settle loop, the stimulus is output to the DUT. While the capturing module does NOT store the captured data results. In case of a Digitizer module the A/D converter does convert, but converted data is not stored. The number of stimuli steps within one loop is dependent of the stimulus memory settings. (CMEM_RET and CMEM_END)

Settle loops can be programmed to let filters on the test board settle. The settle loop counter is situated in both capturing and generating modules. It is recommended to program the number of settle loops to the same value in both capturing and generating module.

CTRIG | Card trigger source and mode

This command applies to: all generating and capturing modules excluding the modules mentioned below.

When the card is put into MMODE, it is ready to start the measurement. On receipt of a trigger, the card actually starts to generate or capture. The trigger source is set with parameter n and can either be internal(from software trigger) or external (from the module front). In case of external trigger, o selects on which logic level the actual trigger occurs. The triggerlevels are 3.3V TTL compatible.

The second parameter is not available for the DIO module (both in high speed and low speed mode). This module has a high sensitive trigger input for the DIO with PLL board and a low sensitive trigger input for previous DIO versions.

This command is not available for the AWG16, AWG18 and WFD16 module. The trigger source is switched simultaneous with the clock selection (CCS). The threshold level for the AWG16, AWG18 or WFD16 module is selectable with the command CTRIG_LEVEL.

CTRIG_STATUS | Card software trigger status

When CTRIG_STATUS is set to 1, a software trigger is sent to the currently selected module. All modules have their software trigger active after initialization, except for the DIO module. During an ATX controlled test, the measurement can be started by setting all used modules in measurement mode and trigger the DIO module. Upon trigger, the DIO starts generating the capture and stimulus clocks.

CTST | Perform card self test

The command starts a diagnostic test on the selected module. In case of an error, the module responds with test error data. If applicable, a voltage test returns the expected and measured voltages.

CV | Card Voltage

Use this command to program MAINDAC (or signal DAC) voltage of the currently selected module. In case of a signal DAC, only one voltage can be programmed. The code programmed to the DAC is calculated using the current range setting (if applicable) of the module. If the module holds a separate offset DAC (DC-baseline DAC), the voltage programmed with the CV command is added to the programmed offset DAC voltage. (refer to the COV command)

Note: a range change (CRA) after the CV command causes the output voltage to change.

In case of a digitizer module, only the CV? command is valid. It returns the input voltage of the active WFD channel. In case of a DRS module, the card responds to the CV command only when it is in ADC controlled mode (COPMODE1). Otherwise only the desired output voltage is stored in the DAC register.

DEM | Display Error Message

With the Error messages setting, the response of the ATX7006 to commands can be set. By default there is no message sent back on receipt of a command. With parameter n set to 1, the ATX7006 only response with an error message when the command is not valid for the chosen module, has an invalid parameter or is unknown. With the parameter n set to 2, the ATX acknowledges a valid command received with an "ok" except for commands that come with a response anyway, like commands ending with a "?" (query command). With the parameter n set to 3, the ATX acknowledges every valid command received including query commands.

Parameter o defines where the response is indicated. By default, responses are sent over LAN and GPIB. Optionally, the response messages are displayed on the ATX controller display.

DIO_ANDMASK | DIO AND mask

This command applies to: DIO Module.

This command defines an ANDMASK operation at the data IO pins of the DIO memory. When set, the data written to the memory is processed by the ANDMASK before memory storage. Likewise, the data that is read from the memory goes through the same process. This mask is active both in measurement mode and in configuration mode. When the AND mask is active during the measurement it is obvious that the mask is set back to the default 0xFFFFFFhex when the module is back in configuration mode.

Example:

The captured AD converter data is 16 bit wide, containing only 10 relevant databits. The 6 most significant DUT are don't care and contain only information on overflow/range etc), So, all bits, except the lower 10 bits should be masked out of the DIO data stream.

In the AND mask, all bits that are relevant should be set to logic 1. To store only the lowest 10 bits, The AND mask value should therefore be 11 1111 1111bin (= 0x3FF) Use the following command sequence:

DIO_CLKDELAY | Set DIO clock delay

This command applies to: DIO Module.

In the stimulus and capture-clock lines, there are delay lines added to fine tune the timing of the capture and stimulus-clocks. With the DIO in a high speed configuration mode, this command can control the timing relation between capture, stimulus and DUT clock. With sample frequencies from 54.4 MHz and higher, the edges of the clocks can be shifted over a whole clock period.

Note: This only sets the value of the delay-lines; skew between the different lines is not taken in account (user should do this themselves).

DIO_XORMASK | DIO XOR mask

This command applies to: DIO Module.

This command defines an XORMASK operation at the data IO pins of the DIO memory. With an XOR function it is possible to convert DUT two’s complement code by inverting the highest bit. Setting a bit in the XOR mask inverts the corresponding bit in the datastream. When set, the data written to the memory is processed by the XORMASK before memory storage. Likewise, the data that is read from the memory goes through the same process. This mask is active both in measurement mode and in configuration mode. When the XOR mask is active during the measurement it is obvious that the mask is cleared when the module is back in configuration mode. The other way round, when the XOR mask is active when the DIO memory is filled with stimulus data, it is obvious to clear the mask during the measurement.

Example

The stimulus signal is 12 bit wide. However, the DUT needs 16 bit data. The most significant DUT bits determine DUT settings like range and DUT operation mode. In the stimulus data, these bits are 0. The desired setting for the highest bits is 1101(bin). To add this bit to the stimulus before writing the stimulus in the DIO memory, the XOR mask should be set to 1101 0000 0000 0000 bin (= 0xD000) Use the following command sequence:

DPS16_STATUS | Dual power supply status

This command applies to: DPS16 Module.

Each channel of the dual power supply has a status register. The register holds the following channel events: Current limit (real-time), Latched current limit status, latched thermal protection status

If the output current of a channel reaches the current limit set with DPS16_CL, bit0 of the returned status value is set. Next, when the over current condition is stopped, this bit is cleared again. In addition, bit 1 reports this over current occurrence and is cleared manually with "DPS16_STATUSCLEAR", bit4 reports a thermal protection event of the channel.

NOTE: After a thermal protection event, all leds and relays of both channels of the DPS are switched off. The module can be used again after clearing this status register bits with "DPS16_STATUSCLEAR"

DRS20_RES | DRS20 resolution

This command applies to: DRS20 Module.

The output of the DAC is monitored by an ADC which adjusts the output voltage more accurate. The accuracy or resolution of this ADC is restricted by the ADC speed. With the DRS20 resolution, the control loop speed and ADC accuracy is set. This setting applies to both channels in the selected module.

back to index

DRS20_SETTLEAREA | set DRS20 settle area in controlled mode

In controlled mode, the actual REFDAC output voltage sampled with an ADC. The ADC data is compared with the expected ADC data. Depending of the difference in actual and desired value, the DAC CODE is adjusted. When the difference in expected and actual ADC code is within the specified SETTLE AREA, (given in LSBs of the measuring ADC) the DAC is adjusted with 0.3uV each loop. One LSB is approximately 2.7uV. The default Settle area of 16 results in a +/- 43uV area around the desired output voltage. When the measured DAC output voltage is within the specified settle area, the DRS channel reflects the settled status. However, when the absolute difference between the ADC reading and the programmed output voltage is greater than the defined settle area, the controller calculates a new DAC correction value, resulting fast correction but a relatively large correction glitch. This setting applies to both channels of the selected DRS20 module.

MR_HIST | Measurement results of last histogram test calculations

The MR_HIST parameters are available after performing the histogram test calculations with CALC_HIST.

The parameters of interest after the histogram calculations are the INL and DNL errors.

For the End point calculation, the reference line will always be y = x (a = 1.0 and b = 0.0). The first trip-point is placed at the ideal ADC transition voltage. This will result in a offset error of 0 LSB. With an "a" of 1.0 for the reference line, the gain error and so the full scale error are 0. The TUE will be equal to the INLE. For the sinusoidal histogram test, the end point reference line can have a small error for the angle "a". This can result in a (small) gain (and so full scale) error. This error is due to the test method.

MR_LIN_TRIP | Measurement results trippoints array (A/D test)

The first trip-point can be greater than 0 if ramp clipping at the start of ramp (parameter q of CALCOPT_LIN_AD is not equal to 0.

The number of used trip-points can be less than the maximum number of trippoints if ramp clipping (parameter q and/or r of CALCOPT_LIN_AD is not equal to 0.

The first trip-point and used trip-points determine the area for the error parameters (INLE, DNLE etc.). The trip-points between the first trip-point and first trip-point + used trip-points are used for the error parameter calculations. The trip-points less than the first trip-points are extrapolated with ideal device LSB values, starting from the first trip-point. The trip-points above the first trip-point + used trip-points are extrapolated with ideal device LSB values, starting from the last trip-point (= first trip-point + used trip-points). The error plot array (MR_LIN_ERR_AD) and error parameters (MR_LIN are calculated with the trip-points starting at the "first trip-point" an using "no. of used trippoints".

The index of the trip-point array starts at 0. Index 0 represents the first trip-point (transition code 0 to 1).

PB_MODE | Set DIO pattern bit mode

This command applies to: DIO Module. DIO FPGA revision 6 (see CID) and higher and firmware release 1.21 and higher are required. For edge sensitive triggering (n=3 or 4) DIO FPGA revision 7 and higher and firmware release 1.24 and higher are required. The pattern bit trigger input should be connected to pin 32 of the DIO connector.

This command configures what event is needed to start the run of one pattern.

There are a number of conditions:

• When a trigger is required to start the pattern (n = 1, 2, 3 or 4), the pattern should be at least 3 steps long.
• When n = 1 or 3, the minimum number of triggers that is required to finish the measurement is (signal steps + 1). When n = 2 or 4, the minimum number of triggers that is required to finish the measurement is signal steps. Where: Signal steps = latency + ((Steps + Settle steps) x (MeasurementLoops + SettleLoops))
• In case of level sensitive triggering, the trigger pulse width should be at least (CCLKDIV / Clocksource frequency) and less than the time of one pattern run (Pattern steps x pattern step time), where pattern steps = (End address - ReturnTo address).
• In case of edge sensitive triggering, a high or low level (pulse width) duration should be at least (CCLKDIV / Clocksource frequency).

There is a latency between the when the trigger becomes active and the first step op the patternbits. In stimulus mode, this delay is 13 (± 1) cycles of the patternbit input clock (clock source / CCLKDIV). In capture mode, this delay is 10 (± 1) cycles of the patternbit input clock (clock source / CCLKDIV).

When a trigger is required to start the pattern (n = 1 or 2) and the trigger is continuously active, the last pattern step (end address) is doubled.

SIGNAL | Signal definition

The signal command defines the signal parameters in the selected signal item. The signal command clears the previous signal definition in the signal item, except for signal 6 and 16. Use the signal_add command to make a compilation of different signal definitions within one signal item.

Analog signals are normalized between 0.0 and 1.0.

E.g. the AWG20 is set to ra 1 (CRA1 = 10.24Vpp). To generate a sine with 1024 samples between 0 and 5.12V, configure a signal with the parameters: n = 12 (analog sine), o = 0.25 (amplitude peak = 25% of the total range = 2.56V), p = 0.75 (offset = 75% of the total range starting from -5.12V = 2.56V) and q = 1024. The command is: SIGNAL 12,0.25,0.75,1024

For generating signals with an AWG module and high signal frequencies relative to the samplefrequency, please be aware of the DA converter frequency response. An online DAC sinc attenuation calculator can be found here.
