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
Dimension string array (255 elements)
SYST:ERR? Read error queue
enter statement Enter error string response
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 key, or a 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
Set burst count to 3 cycles
TRIG:SLOP POS
Set polarity to rising edge
TRIG:SOUR EXT Select external trigger source
BURS:STAT ON
Enable burst mode
