Basic pulse programming example

1
Step Action
1 Select Pulse Mode, and set pulse
width and pulse delay.
2 Set pulse measurement speed.
3 Set pulse count.
4 Select source.
5 Set source range, level, compliance.
6 Set measure function, range.
7 Turn on output and read data.
1. Steps correspond to front panel steps in "Front panel pulse-measure procedure," page
2. Commands must be sent in order given.
3. Instrument must be addressed to talk after :READ? to acquire data.
Pulse-measure considerations
Measurement speed
Measurement speed for the Pulse Mode can be set from 0.004 to 0.100 PLC. If the speed
setting while in the DC Mode is >0.10 PLC, it will change to 0.004 when the Pulse Mode
is selected. If the speed setting is <0.10 PLC, that setting will be retained when the Pulse
Mode is selected. If the Pulse Mode speed setting is <0.01, it will change to 0.01 when the
DC Mode is selected.
For remote operation, the parameter value for the [:SENSe] ... :NPLC <b> commands is
limited to 0.10. Details are provided in
