Reading A Query Response; Selecting A Trigger Source - Agilent Technologies E3647A User Manual

Simplified Programming Overview

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
''SYST:ERR?''
bus enter statement
print statement

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''
''CURR:TRIG 1.0''
''TRIG:SOUR IMM''
''INIT''
