Example
:SOUR1:MOD:TYPE FM /*Sets the modulation type of CH1 to FM.*/
:SOUR1:MOD:TYPE? /*Queries the modulation type of CH1 and the query returns FM.*/
:SOURce:PERiod
Command List:
 [:SOURce[<n>]]:PERiod[:FIXed]
[:SOURce[<n>]]:PERiod[:FIXed]
Syntax
[:SOURce[<n>]]:PERiod[:FIXed] {<period>|MINimum|MAXimum}
[:SOURce[<n>]]:PERiod[:FIXed]? [MINimum|MAXimum]
Description
Sets the waveform (basic waveforms and arbitrary waveforms) period of the specified channel.
Queries the waveform (basic waveforms and arbitrary waveforms) period of the specified channel.

Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 The period and frequency are the reciprocal of each other. For the frequency ranges of different
models and different waveforms of DG2000 series, refer to Table 2-1.
 If the period in the command is smaller than the corresponding period lower limit, the system sets the
waveform period of the specified channel to the corresponding period lower limit.
 When the waveform type of the specified channel is changed (
[:SOURce[<n>]]:APPLy?), the
instrument still uses the period if the period is valid for the new waveform type; the instrument
displays a prompt message and sets the period to the period lower limit of the new waveform type
automatically if the period is invalid for the new waveform type.
Return Format
The query returns the waveform period in scientific notation, with 7 effective digits. For example,
1.000000E-01 (the waveform period is 0.1 s).
Example
:SOUR1:PER 0.1 /*Sets the waveform period of CH1 to 1 s.*/
:SOUR1:PER? /*Queries the waveform period of CH1 and the query returns 1.000000E-01.*/
