This function resets the PG2 to the default settings for whichever pulse mode
(standard, full-arb, or Segment ARB) is presently selected:
int pulse_init(INSTR_ID instr_id)
instr_id
This function resets both channels of the PG2 to the default settings. The default setting
for each parameter is listed in the Format section for each LPT function.
The function can be used to specify which pulse mode to reset. Using this
pg2_init
function selects the specified pulse mode and its default settings.
pg2_init
The following function resets the PG2 to the default settings for the presently selected
pulse mode:
pulse_init(VPU1)
This function sets the output impedance for the load (DUT).
int pulse_load(INSTR_ID instr_id, long chan, double load)
instr_id
chan
load
DUT impedance can be independently set for each PG2 channel. The DUT impedance
can be set from 1 Ω to 10 M Ω, depending on the programmed pulse high and low
values.
