Reading a Query Response
Only the query commands (commands that end with "?") will instruct
the function generator to send a response message. Queries return
internal instrument settings. For example, the following command string
sent from your computer will read the function generator's error queue
and retrieve the response from the most recent error.
dimension statement
SYST:ERR?

Selecting a Trigger Source
When Sweep or Burst is enabled, the function generator will accept an
immediate internal trigger, a hardware trigger from the rear-panel
Trig In connector, a manual trigger from the front-panel
software (bus) trigger. By default, the internal trigger source is selected.
If you want to use an external or a software trigger source, you must first
select that source. For example, the following command strings sent from
your computer will output a 3-cycle burst each time the rear-panel
Trig In connector receives the rising edge of a TTL pulse.
BURS:NCYC 3
TRIG:SLOP POS
TRIG:SOUR EXT
BURS:STAT ON
