pulse_meas_wfm
This command configures waveform measurements.
Usage
int pulse_meas_wfm(int instr_id, int chan, int AcquireType, int AcquireMeasV, int
AcquireMeasI, int AquireTimeStamp, int LLEComp);
instr_id
The instrument identification code of the PMU, such as PMU1 or PMU2
chan
Channel number of the pulse card: 1 or 2
AcquireType
Acquisition type:
• Discrete: 0
•
Average: 1
AcquireMeasV
Return voltage measurements:
• Disable: 0
•
Enable: 1
AcquireMeasI
Return current measurements:
• Disable: 0
•
Enable: 1
AcquireTimeStamp
Return time stamp readings (must be enabled to measure waveforms):
• Disable: 0
• Enable:
1
LLEComp
Load line effect compensation (LLEC):
• LLEC disabled: 0
• LLEC enabled:
1
Pulsers
4225-PMU
Pulse modes
Standard
Details
Use the pulse_meas_wfm command to configure waveform measurements; select the data
acquisition type, set the readings to be returned, enable or disable time stamp, and set load-line
effect compensation (LLEC). See Waveform measurements (on page 5-72
) for details.
LLEC is only performed for standard pulse IV testing using PMU measure ranges. It is not performed
when using 4225-RPM measure ranges. The active RPM circuitry provides its own analog LLEC
(assuming a short cable from the RPM to the DUT).
