[:SOURce[<n>]]:FREQuency[:FIXed]

Syntax

[:SOURce[<n>]]:FREQuency[:FIXed] {<frequency>|MINimum|MAXimum}

[:SOURce[<n>]]:FREQuency[:FIXed]? [MINimum|MAXimum]

Description

Set the frequency of the waveform (basic waveforms and arbitrary waveform) of

the specified channel.
Query the frequency of the waveform (basic waveforms and arbitrary waveform) of

the specified channel.

Explanation

 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related

parameters of CH1 by default.

 If the frequency value in the command is greater than the corresponding

frequency upper limit or lower than the corresponding frequency lower limit,

the waveform frequency of the specified channel will be set to the frequency

upper limit or lower limit.

 When the waveform type of the specified channel is changed, the instrument

still uses the frequency if the frequency is valid for the new waveform type; the

instrument will display prompt message and set the frequency to the

frequency upper limit of the new waveform type automatically if the frequency

is invalid for the new waveform type.

Return Format

The query returns the waveform frequency in scientific notation with 7 effective

digits, for example, 1.000000E+02 (the waveform frequency is 100Hz).

Example

:SOUR1:FREQ 100 /*Set the waveform frequency of CH1 to 100Hz*/
:SOUR1:FREQ? /*Query the waveform frequency of CH1 and the query

returns 1.000000E+02*/
