At this time, the displayed frequency value= RF output frequency ×mul
frequency offset. However, the actual frequency output is still the frequency with no
multiplier and frequency offset added. When Freq Offset is set to zero, the indicator
disappears.
Setting format: [:SOURce]:FREQuency:OFFSet <val>
Query format: [:SOURce]:FREQuency:OFFSet?
Parameter:
<FreqOffs> Freq Offset
Range: 0Hz[-325GHz
，
+325GHz].
Example: :FREQuency:OFFSetr 10GHz Freq Offset of the signal generator is 10 MHz.
Reset status: 0Hz

[:SOURce]:FREQuency:REFerence <FreqRef>
Function: This command is used for setting the frequency reference function. The set value can
function well when the frequency reference switch is on. See the command
―
:FREQuency:REFerence:STATe
‖. Frequency reference indicator―*‖ is displayed in
the frequency display area. In this case, the frequency reference value will be
subtracted from the set CW output signal. For example: The current CW output
frequency is 1 GHz. If Freq Ref is set to 1 GHz, the CW output frequency displayed at
this time will be based on 0 Hz frequency reference, so frequency display area will
display 1 MHz; if CW frequency is set to 1 MHz, frequency display area will display 1
MHz and the actual output frequency is 1.001 GHz.
