[:SOURce[<n>]]:BURSt:NCYCles
Syntax
[:SOURce[<n>]]:BURSt:NCYCles {<cycles>|MINimum|MAXimum}
[:SOURce[<n>]]:BURSt:NCYCles? [MINimum|MAXimum]
Description
Sets the number of cycles in the N cycle burst of the specified channel.
Queries the number of cycles in the N cycle burst of the specified channel.
Parameter
Name
Type
Range
Default
[<n>]
Discrete
1|2
1
<cycles> Integer
1 to 1,000,000 (external or manual trigger)
1 to 500,000 (internal trigger)
1
Remarks
 In the N cycle burst mode (
[:SOURce[<n>]]:BURSt:MODE), the signal generator outputs the
waveform with the specified number of cycles when receiving the trigger signal.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the number of cycles in scientific notation, with 7 effective digits. For example,
1.000000E+01 (the number of cycles is 10).
Example
:SOUR1:BURS:NCYC 10 /*Sets the number of cycles in the N cycle burst of CH1 to 10.*/
:SOUR1:BURS:NCYC? /*Queries the number of cycles in the N cycle burst of CH1 and the query
returns 1.000000E+01.*/
[:SOURce[<n>]]:BURSt:PHASe
Syntax
[:SOURce[<n>]]:BURSt:PHASe {<phase>|MINimum|MAXimum}
[:SOURce[<n>]]:BURSt:PHASe? [MINimum|MAXimum]
Description
Sets the start phase of the burst function of the specified channel.
Queries the start phase of the burst function of the specified channel.
Parameter

Default
[<n>]

1
<phase>
Real
0° to 360°
0°
Remarks
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the start phase in scientific notation, with 7 effective digits. For example, 1.000000E+01
(the start phase is 10°).
Example
:SOUR1:BURS:PHAS 10 /*Sets the start phase of the burst function of CH1 to 10°.*/
:SOUR1:BURS:PHAS? /*Queries the start phase of the burst function of CH1 and the query returns
1.000000E+01.*/
