pulse_ranges

This command sets the voltage pulse range and voltage/current measure ranges.

int pulse_ranges(int instr_id, int chan, double VSrcRange, int Vrange_type, double

Vrange, int Irange_type, double IRange);

Standard, Full Arb, Segment Arb

The Vrange_type, Vrange, Irange_type, and Irange parameters are ignored by the PGU.

Autorange (0) and limited autorange (1) are not valid for the Segment Arb pulse mode.

You can set the source range independently for each PGU channel. There are two ranges for the

output level: 5 V and 20 V (into a 50 Ω DUT load). Selecting the 5 V range also selects high-speed

pulse output. For the 5 V high-speed range, the

next pulse trigger is initiated.

For the PGU, use this command to set the voltage source range for pulse output.

For the PMU, use this command to:

Set the voltage source range for pulse output.

Set the voltage and current measure range types.

Set the actual voltage and current measure ranges.
