Burst Mode - Hantek HDG 2000 Series User Manual

determined by the total of the hold time, sweep time and return time.
 With the External source, the instrument accepts a hardware trigger on the rear-panel Ext Trig
connector and initiates one sweep each time Ext Trig receives a TTL pulse with the specified
polarity.
 The trigger period must be greater than or equal to the specified sweep time.
 With the Manual source, the instrument outputs one sweep each time the front-panel [Trigger]
key is pressed.

3.8 Burst Mode

The instrument can output a waveform for a specified number of cycles, called a burst. Burst is
allowed with sine, square, triangle, ramp, pulse or arbitrary waveforms (noise allowed only in
gated burst mode; DC is not allowed).
To Select Burst
Burst cannot be enabled when sweep or modulation is enabled. Enabling burst turns off sweep
and modulation.
 To avoid multiple waveform changes, enable burst mode after configuring other parameters.
 Front-Panel:
 SCPI: SOURce<n>:BURSt ON|OFF
Burst Mode
Burst has two modes, described below. Selected mode controls allowable trigger source, and
which other burst parameters apply.
 Triggered Burst Mode (N Cycle, INFinity Cycle): The instrument outputs a waveform for
specified number of cycles (burst count) each time trigger is received. After outputting specified
number of cycles, instrument stops and waits for next trigger. The instrument can use an
internal trigger to initiate burst, or you can provide external trigger by pressing the front-panel
[Trig Menu] key, applying trigger signal to front-panel TRIG connector, or sending software
trigger command from remote interface. INFinity Cycle: The instrument outputs a waveform
each time trigger is received. After outputting infinity cycle, instrument stops and waits for next
trigger.
 External Gated Burst Mode: Output waveform is on or off, based on level of external signal
