To Select Burst

Press Burst key to output a burst using the present settings for frequency, output amplitude, and offset voltage. (the backlight of the key goes on)

Note:

A. The function generator will not allow burst to be enabled at the same time that sweep or any modulation mode is enabled. When you enable burst, the sweep or modulation mode is turned off.

B. You must enable burst before setting up any of the other burst parameters.

Burst Type


You can use burst in one of three modes as described below. The function generator enables one burst
mode at a time based on the trigger source and burst source that you select (see the table below).

WisdomAugust

N Cycle Burst (Triggered Burst Mode)

In this mode (default), the function generator outputs a waveform with a specified number of cycles

(burst count) each time a trigger is received. After the specified number of cycles have been output,

the function generator stops and waits for the next trigger. You can configure the function generator

to use an internal trigger to initiate the burst or you can provide an external trigger by applying a trigger

signal to the front-panel Sync/Mod/Trig connector, or sending an internal trigger command manually

by pressing the front-panel Trigger key.

N Cycle Burst (Internal Trigger)

WisdomAugust

Infinite Cycle Burst (Triggered Burst Mode)

In this mode , the function generator outputs continuous waveforms with a infinite number of cycles

after receiving trigger signal. You can configure the function generator to use an external trigger by

applying a trigger signal to the front-panel Sync/Mod/Trig connector, or sending an trigger command

manually by pressing the front-panel Trigger key.

Infinite Cycle Burst

Gated Burst ( External Gated Burst Mode)

In this mode, the output waveform is either “on” or “off ” based on the level of the external signal applied

to the front-panel Sync/Mod/Trig connector. When the gate signal is true, the function generator outputs

a continuous waveform. When the gate signal goes false, the current waveform cycle is completed and

then the function generator stops while remaining at the voltage level corresponding to the starting burst

phase of the selected waveform. For a noise waveform, the output stops immediately when the gate signal

goes false.

Gated Burst

When the gated mode is selected, the burst count, burst period, and trigger source are ignored (these

parameters are used for the triggered burst mode only). If a manual trigger is received, it is ignored and

no error will be generated.

When the gated mode is selected, you can also select the polarity of the signal on the front-panel

Sync/Mod/Trig connector.

Front-Panel Operation: After enabling bursts, press the N Cycle (triggered), Inf Cycle or Gate softkey.

To select the polarity of the external gate signal on the Sync/Mod/Trig connector, press the Polarity

softkey. The default polarity is Positive.
