Parameters:
<State> 0 | 1 | OFF | ON
*RST:

Example: FREQ:PHAS:CONT:STAT ON
activates phase continuous mode.
Manual operation: See "Phase Continuous Active" on page 208
[:SOURce<hw>]:FREQuency:SPAN <Span>
Determines the extent of the frequency sweep range. This setting in combination with
the center frequency setting (
[:SOURce<hw>]:FREQuency:CENTer
) defines the
sweep range.
This parameter is related to the start and stop frequencies. If you change the fre-
quency, the span changes accordingly.

*RST: 400E6
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 266
[: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.
