Defines a Segment ARB pulse-measure sequence
This function defines the parameters for a Segment ARB pulse-measure sequence.

For the PMU, use this function to configure each channel to output its own unique
®
Segment ARB waveform and perform measurements. For the PGU, use this function
to configure each channel to output its own unique Segment ARB waveform.
A Segment ARB sequence is made up of user-defined segments (up to 2048 per
channel). Each sequence can have a unique start voltage, stop voltage, time interval,
output trigger level (TTL high or low), output relay state (open or closed), pulse
Return to Section Topics
Instrument ID: VPU1, VPU2, PMU1, PMU2, and so on.
The pulse generator channel: 1 or 2.
Sequence ID number (1 to 512, per channel) to uniquely
identify this sequence.
Total number of segments in this sequence.
An array of start voltage levels.
An array of stop voltage levels.
An array of segment time durations (in seconds with 10 ns
resolution, 20 ns minimum).
An array of trigger values: 0 (trigger low) or 1 (trigger high).
These values are for trigger output only.
An array of values to control the high endurance output relay:
0 (open) or 1 (closed).
PMU only: An array of measure types:
0 = No measurements for this segment
1 = Spot mean discrete (see
2 = Waveform discrete (see
3 = Spot mean average
4 = Waveform average
PMU only: An array of start measurement times (in seconds,
with 10 ns resolution). A zero (0) second setting sets measure
to start at the beginning of the segment.
PMU only: An array of stop measurement times (in seconds,
with 10 ns resolution). This is the elapsed time, within the
segment, when the measurement stops.
The 4220-PGU does not have pulse-measure capability.
When this function for the PGU is called, the parameter
values for MeasType, MeasStart, and MeasStop are
ignored.
