BURSt:INTernal:PERiod? [MINimum|MAXimum]

The burst period in seconds will be returned.

BURSt:PHASe {<angle>|MINimum|MAXimum}

Specify the starting phase in degrees or radians according to UNIT:ANGL

command. The range is from -360 degrees to +360 degrees (or from -2∏ to

+2∏ radians) and the default is 0 degree (0 radians).

--For sine, square and ramp waveform, zero degrees is the point at which the

waveform crosses zero volts or the dc offset in a positive going direction. For

arbitrary waveform, it is the first waveform point downloaded to memory. The

burst phase has no effect on pulse or noise waveform.

--In the gated burst mode, when the gate signal turns false, the current

waveform is complete and the waveform generator stops and the output

remains at the voltage level corresponding to the starting burst phase.

BURSt:PHASe? [MINimum|MAXimum]

The starting phase in degree or radians will be returned.

BURSt:STATe {OFF|ON}

Disable or enable the burst mode. To avoid multiple waveform changes, you can

enable burst after setting the modulation parameters. The waveform generator

allows only one of burst, sweep and modulations enabled at one time. As long as

one is enabled, the other will be turned off.

BURSt:STATe?

“0” (OFF) or ”1” (ON) will be returned.

BURSt:GATE:POLarity {NORMal|INVerted}

Specify whether the waveform generator uses true-high or true-low logic levels

on the rear-panel Ext Trig connector for an externally-gated burst. The default is

NORM (true-high logic).
