Using the Internal
Trigger Generator
Using The Instrument 3-22
The internal trigger generator is a free-running generator which is
asynchronous with the main output generator. When the internal
trigger source is selected, the front panel TRIG IN signal is inactive.
The internal trigger generator is also available in Burst mode, but has
no effect in Gated mode. To use the internal trigger generator,
place the instrument in Triggerd mode, but select the internal trigger
generator as the trigger source. Then use the following command to
program an internal trigger period:
TRIGger:TIMer <value>
The period of the internal trigger generator can be programmed
from 60 µs to 1000 s. The default period is 100 µs. The internal
trigger generator is ignored when either an external or TTLT source
is enabled.The query:
TRIGger:TIMer?
queries the period of the internal trigger generator and returns a
value in seconds.
