Reading a query response
Only the query commands (commands that end with “?”) will instruct the power
supply to send a response message. Queries return either output values or
internal instrument settings. For example, the following statements executed from
your computer will read the power supply’s error queue and print the most recent
error:
Selecting a trigger source
The power supply will accept a bus (software) trigger or an immediate internal
trigger as a trigger source. By default, the BUS trigger source is selected. If you
want the power supply to use an immediate internal trigger, you must select
IMMediate. For example, the following statements executed from your computer
will set to an output of 3 V/1 A immediately:
dimension statement
Dimension string array (80 elements)
“SYST:ERR?”
Read error queue
bus enter statement
Enter error string into computer
print statement
Print error string
“VOLT:TRIG 3.0”
Set the triggered voltage level to 3.0 V
“CURR:TRIG 1.0”
