pulse_meas_sm
This command configures spot mean measurements.
Usage
int pulse_meas_sm(int instr_id, int chan, Int AcquireType, int AcquireMeasVAmpl,
int AcquireMeasVBase, int AcquireMeasIAmpl, int AquireMeasIBase, int
AquireTimeStamp, int LLEComp);
instr_id
The instrument identification code of the pulse card, such as VPU1 or VPU2
chan
Channel number of the pulse card: 1 or 2
AcquireType
Acquisition type:
• Discrete: 0
•
Average: 1
AcquireMeasVAmpl
Return amplitude voltage measurements:
• Disable: 0
• Enable:
1
AcquireMeasVBase
Return base level voltage measurements:
• Disable: 0
• Enable:
1
AcquireMeasIAmpl
Return amplitude current measurements:
• Disable: 0
• Enable:
1
AcquireMeasIBase
Return base current level measurements:
• Disable: 0
• Enable:
1
AcquireTimeStamp
Return time stamp readings:
• Disable: 0
•
Enable: 1
LLEComp
Load-line effect compensation (LLEC):
• All LLEC disabled: 0
•
Voltage LLEC on for pulse amplitude only: 1
Pulsers
4225-PMU
Pulse modes
Standard
Details
Use the pulse_meas_sm command to configure spot mean measurements; select the data
acquisition type, set the readings to be returned, enable or disable time stamp, and set load-line
effect compensation (LLEC).
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).
