Description Use this command to program the period of the PLL (INTernal2) when it

is used as the

: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

Select internal osc.as pulse period source

Set pulse period to 50 ns

Select PLL as triggering source
