Parameter
Name
<n>
<bool>
Remarks
•
The frequency coupling function is not available for DG821 Pro (unless the two-
channel upgrade option is installed).
•
When the coupling mode is set to "ratio", if the frequency, amplitude, or phase
of either channel exceeds the upper/lower limit after calculation according to
the coupling rules due to modifying the coupling ratio, switching waveform, or
changing waveform parameters, the generator will automatically adjust the
waveform parameters to avoid parameter overlimit.
•
When the coupling mode is set to "deviation", if the frequency, amplitude or
phase of either channel exceeds the upper/lower limit after calculation
according to the coupling rules due to modifying the coupling deviation, the
generator will automatically adjust the coupling deviation to avoid parameter
overlimit; if it is due to switching waveform or changing waveform parameters,
the corresponding coupling function is disabled.
•
The frequency coupling function is available only when the output modes of
both channels are set to Continuous and the output waveform is set to Sine,
Square, or Ramp.
•
When [:SOURce[<n>]] or [<n>] is omitted, it is interpreted as CH1.
Return Format
The query returns 0 or 1.
Examples
:SOURce1:FREQuency:COUPle:STATe ON /*Enables the frequency
coupling function for CH1.*/
:SOURce1:FREQuency:COUPle:STATe? /*Queries the on/off status of
the frequency coupling function for CH1. The query returns 1.*/
