KXCI pulse generator commands
The KXCI commands to control pulse generators are documented in the following topics.
The following documentation includes the corresponding LPT library functions for each KXCI
command string. Refer to LPT functions for PGUs and PMUs (on page 13-91) for details on pulsing
functions.
PD
This command sets the output impedance (pulse load).
Usage
PD A, BBB.BBBB
A
Pulse card channel number: 1 to 8; the largest value is the number of channels in
the system
BBB.BBBB
Pulse load, in ohms: 1.0 to 10e6; default 50.0
Corresponding LPT library function
pulse_load (on page 13-145)
Details
You can use this command to set the DUT impedance of the load (DUT) independently for each
channel from 1 Ω to 10 MΩ.
Example
PD 1, 1e3
This command string sets channel 1 of pulse card 1 for an output impedance of 1 kΩ.
