stop frequency ([:SOURce[<n>]]:FREQuency:STOP). It is only available in step sweep
(
[:SOURce[<n>]]:SWEep:SPACing).
 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 steps in scientific notation, with 7 effective digits. For example,
5.000000E+00 (the number of steps is 5).
Example
:SOUR1:SWE:STEP 5 /*Sets the number of steps of the sweep of CH1 to 5.*/
:SOUR1:SWE:STEP? /*Queries the number of steps of the sweep of CH1 and the query returns
5.000000E+00.*/
[:SOURce[<n>]]:SWEep:TIME
Syntax
[:SOURce[<n>]]:SWEep:TIME {<seconds>|MINimum|MAXimum}
[:SOURce[<n>]]:SWEep:TIME? [MINimum|MAXimum]
Description
Sets the sweep time of the specified channel.
Queries the sweep time of the specified channel.

Remarks
 Sweep time: sets the time required for the instrument to sweep from the start frequency
(
[:SOURce[<n>]]:FREQuency:STARt) to stop frequency ([:SOURce[<n>]]:FREQuency:STOP).
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 The generator will restart to sweep and output from the specified "Start Frequency" once the sweep
time is modified.
Return Format
The query returns the sweep time in scientific notation, with 7 effective digits. For example, 5.000000E+00
(the sweep time is 5 s).
Example
:SOUR1:SWE:TIME 5 /*Sets the sweep time of CH1 to 5 s.*/
:SOUR1:SWE:TIME? /*Queries the sweep time of CH1 and the query returns 5.000000E+00.*/
