pulse_meas_timing
This command sets the measurement windows.
Usage
int pulse_meas_timing(int instr_id, int chan, double, StartPercent, double
StopPercent, int NumPulses);
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
StartPercent
Start location for measurements:
• Spot mean measurements: Start location, specified as a percentage of the
widths for the amplitude and base level (see Details)
• Waveform: Pre-data for the amplitude, specified as a percentage of the
amplitude pulse duration (see Details)
StopPercent
Stop location for measurements:
• Spot mean measurements: Stop location, specified as a percentage of the
widths for the amplitude and base level (see Details)
• Waveform: Post-data for the amplitude, specified as a percentage of the
amplitude pulse duration (see Details)
NumPulses
Number of pulses to output and measure (1 to 10,000)
Pulsers
4225-PMU
Pulse modes
Standard
Details
Use the pulse_meas_timing command to set measurement timing. For spot mean measurements,
portions of the amplitude and base levels are specified for sampling. For pre-data and post-data
waveform measurements, a percentage of the entire pulse duration is specified. See
Measurement
timing (on page 5-74) for details on pulse measurement timing.
The figure below shows example start and stop locations spot mean measurements are made. Three
measured samples are taken on the amplitude and six samples are taken on the base level. The start
and stop percentage values indicate the portions of the pulse that are sampled.
