Source[<N>]]:Frequency:center - Rigol DG800 Pro Series Programming Manual

Return Format
The query returns the frequency in scientific notation. For example, the query might
return +1.000000000000000E+06, indicating that the frequency is 1 MHz.
Examples
:SOURce1:FREQuency 1000000 /*Sets the frequency of the continuous
waveform to 1 MHz for CH1.*/
:SOURce1:FREQuency? /*Queries the frequency of the continuous
waveform for CH1. The query returns +1.000000000000000E+06.*/

Description
Sets or queries the center frequency of the sweep mode for the specified channel.
Parameter
Name
<n>
<frequency>
<lim_set>
<lim_query>
Remarks
• You can set the sweep boundaries using the center frequency and frequency
span (
different center frequency and frequency span ranges. Also, the center
frequency and frequency span affect each other.
• Center Frequency = (Start Frequency + Stop Frequency)/2. Frequency Span =
Stop Frequency - Start Frequency.
• When [:SOURce[<n>]] or [<n>] is omitted, it is interpreted as CH1.
Return Format
The query returns the center frequency in scientific notation. For example, the query
might return +5.000000000000000E+03, indicating that the center frequency is 5
kHz.
