:ARM:SOURce
for internal triggering of pulses, bursts or
patterns.
If you are using the PLL as
:TRIGger:SOURce
use the
[:SOURce]:PULSe:PERiod
command to set the pulse period.
Example To set up bursts of four 50 ns pulses occurring every 500 ns:
:TRIG:SOUR INT
:PER 50 NS
:ARM:SOUR INT2
:ARM:SENS EDGE
:ARM:PER 500ns
:ARM:TRIG:COUNT 4
