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:
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
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:
‘‘VOLT:TRIG 3.0’’ Set the triggered voltage level to 3.0 V
‘‘CURR:TRIG 1.0’’ Set the triggered current level to 1.0 A
‘‘TRIG:SOUR IMM’’ Select the immediate trigger as a source
‘‘INIT’’ Cause the trigger system to initiate
