[:SOURce<hw>]:FREQuency[:CW|FIXed] <Fixed>

Sets the frequency of the RF output signal.

In CW mode, see FREQ:MODE CW|FIXed, the instrument operates at a fixed frequency.

In sweep mode FREQ:MODE SWE, the value applies to the sweep frequency and the instrument processes the frequency settings in defined sweep steps.

You can enter either a numerical frequency value, of decrease or increase the current frequency step by step with FREQ UP and FREQ DOWN. The frequency is then increased or decreased by the value [:SOURce<hw>]:FREQuency:STEP[:INCRement] in FREQ:STEP:MODE USER.

Note:

A defined offset and the multiplier factor affect the sweep range and therefore all correlated parameters. The set frequencies are only absolute values, if the offset = 0 and the multiplication factor = 1. The multiplier multiplies the frequencies accordingly, and the offset ≠ 0 shifts the frequencies corresponding to the set value.

The actual frequency at the RF output does not change, but rather the value queried with [:SOUR]:FREQ?, according to the formula:

fFREQ = fRFout * fMULTiplier + fOFFSet

Correlation: FREQ for FREQ:MODE SWE is linked to the sweep frequency.
