Example:
FREQ:CENT 400 MHz
sets the center frequency of the frequency sweep to 400 MHz.
FREQ:SPAN 200 MHz
sets a span of 200 MHz. This sets the sweep range to 300 MHz
to 500 MHz.
Manual operation: See "Span - Frequency Sweep" on page 161
[: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.

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.

*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 " on page 160
[:SOURce<hw>]:FREQuency:STOP <Stop>
Sets the stop frequency for the RF sweep.
This parameter is related to the center frequency and span. If you change the fre-
quency, these parameters change accordingly.

Note: A defined offset affects the sweep range and consequently all correlating param-
eters. The set frequencies are only absolute values, if the Offset = 0. Offset ≠ 0 shifts
the frequencies according to the offset value.
