TRIGger:BURSt ON
TRIGger:COUNt <counts>
INIT:CONT OFF places the Model 301/302 in a non-continuous mode.
TRIG:BURS ON turns the burst function on. The TRIG:COUN
specifies the number of output waveforms after a qualified trigger
signal. To ensure proper operation, enable Burst mode after setting up
the burst parameters. When Burst mode is enabled, previously
programmed trigger or gate modes turn off automatically.
The query:
TRIGger:BURSt?
queries the state of Burst mode and returns "0" (OFF) or "1" (ON).
The query:
TRIGger:COUNt?
queries the burst count and returns an integer.
In WaveWiz, select Burst mode by clicking the diamond shaped Burst
button under mode on the Trigger tab. (see Figure 3.12 above).
Selecting the Trigger
Source
When an external source is not available, one has the option of using
the built-in trigger generator to stimulate its output.
Use the following command to select the trigger source for the
instrument:
TRIGger:SOURce:ADVance {EXTernal | INTernal}
EXT is the default trigger source for the Model 301/302. Select INT to
use the internal trigger generator. Remember to program the period of
the internal generator (as shown later).
The query:
TRIGger:SOURce:ADVance?
queries the trigger source and returns EXT or INT.
In WaveWiz, select trigger source mode by clicking the relevant
diamond shaped button under source on the Trigger tab. (see Figure
3.12 above).
