l In gated mode, burst count, burst period, and trigger source are ignored (used for triggered burst only). Manual
triggers ignored; no error generated.
l In gated mode, you can specify polarity of signal on rear-panel Ext Trig connector ([SOURce[1|2]:]BURS-
t:GATE:POLarity {NORMal|INVerted}). Default is NORMal (true-high).

Waveform Frequency
You can specify the signal frequency during the burst in triggered and external gated modes. In the triggered mode, the
number of cycles specified by the burst count is output at the waveform frequency. In the external gated mode, the
waveform frequency is output when the external gate signal is true.
This differs from the "burst period," which specifies interval between bursts (triggered mode only).
l Waveform frequency: 1 µHz to 30 MHz (limited to 200 kHz for ramps). The default value is 1 kHz. (For an inter-
nally triggered burst waveform, the minimum frequency is 126 µHz.)
l Front Panel:
l SCPI: [SOURce[1|2]:]FREQuency {<frequency>|MIN|MAX}
The APPLy command configures a waveform with one command.
