Sets the center frequency of the RF sweep range.
The range is defined by this center frequency and the specified
fCENTer - (fSPAN/2) ... fCENTer + (fSPAN/2)
with:
fSPAN = fSTOP - fSTARt
The center frequency directly relates to the span, and the start and stop frequencies. If you change one of these parameters, the center frequency changes accordingly.
fCENTer = (fSTOP + fSTARt)/2
Note: You can select any frequency within the setting range. The range is defined with the parameters
A defined offset and the multiplier factor affect the sweep frequency 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.
300 kHz * fMULTiplier + fOFFSet ... fmax * fMULTiplier + fOFFSet

Example: | FREQ:CENT 400 MHz sets the center frequency for the frequency sweep to 400 MHz. FREQ:SPAN 200 MHzsets a span of 200 MHz. This sets the sweep range to 300 MHz to 500 MHz. | |||||||
