[:SOURce<hw>]:FREQuency:STARt <Start>

Sets the start frequency for the RF sweep.

This parameter relates to the center frequency and span. If you change the frequency, these parameters change accordingly.

fSTARt > fSTOP is permitted.

fSTARt = (fCENTer - fSPAN/2).

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.

fSTARt * fMULTiplier + fOFFset ... fSTOP * fMULTiplier + fOFFset

Parameters:
<Start>
float
Range: full frequency range
Increment: see the data sheet: RF characteristics > Resolution of setting
*RST:100 MHz
Example: FREQ:STARt 1 MHz

sets the start frequency for the frequency sweep to 1 MHz.

FREQ:STOP 2 GHz

sets the stop frequency for the frequency sweep to 2 GHz.

Manual operation: See "Start Freq - Frequency Sweep"
