Return Format
The query returns the burst period in scientific notation, with 7 effective digits. For example, 1.000000E-01
(the burst period is 0.1 s).
Example
:SOUR1:BURS:INT:PER 0.1 /*Sets the internal burst period of the N cycle burst of CH1 to 0.1 s.*/
:SOUR1:BURS:INT:PER? /*Queries the internal burst period of the N cycle burst of CH1 and the
query returns 1.000000E-01.*/
[:SOURce[<n>]]:BURSt:MODE
Syntax
[:SOURce[<n>]]:BURSt:MODE {TRIGgered|INFinity|GATed}
[:SOURce[<n>]]:BURSt:MODE?
Description
Sets the burst type of the specified channel to N cycle (TRIGgered), Infinite (INFinity), or Gated (GATed).
Queries the burst type of the specified channel.
Parameter
Name Type Range Default
[<n>] Discrete 1|2 1
{TRIGgered|INFinity|GATed} Discrete TRIGgered|INFinity|GATed TRIGgered
Remarks

DG900 can output three types of bursts, including N cycle, Infinite and Gated.

In N Cycle mode, the generator will output waveforms with a specified number of cycles after receiving
the trigger signal. The waveform functions that support the N cycle burst include Sine, Square, Ramp,
Pulse, Arbitrary, PRBS, RS232, and Sequence. For N cycle burst, "Internal", "External", or "Manual"
trigger source could be selected. Besides, you can also set the parameters of "Burst Period" (internal
trigger), "Delay", "Trig In" (external trigger), and "Trig Out" (internal and manual trigger).

In Infinite mode, the cycle number of the waveform is set as an infinite value. The generator outputs
a continuous waveform after receiving a trigger signal. The waveform functions that support the
Infinite burst include Sine, Square, Ramp, Pulse, Arbitrary, PRBS, RS232, and Sequence. For the
Infinite burst, "External" or "Manual" trigger source could be selected. Besides, users can set the
parameters of "Delay", "Trig In" (external trigger), and "Trig Out" (manual trigger).

In the gated burst mode, the signal generator controls the waveform output according to the level of
the external signal input from the rear-panel [Sync/Ext Mod/Trig/FSK] connector of the
corresponding channel. The waveform functions that support the Gated burst include Sine, Square,
Ramp, Pulse, Noise, Arbitrary, PRBS, RS232, and Sequence. Gated Burst could only be triggered by
"External" trigger source.

When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns TRIG, INF, or GAT.
Example
:SOUR1:BURS:MODE TRIG /*Sets the burst type of CH1 to TRIG (N cycle).*/
:SOUR1:BURS:MODE? /*Queries the burst type of CH1 and the query returns TRIG.*/
