FREQ:STAR
sets the start frequency to 100 MHz.
FREQ:STOP
sets the stop frequency to 500 MHz.
SWE:SPAC LIN
sets linear sweep spacing.
SWE:STEP 2 MHz
sets the step width for linear sweep spacing to 2 MHz (RF sweep
at the RF output. The number of sweep steps for linear sweep
spacing (POINts) is automatically set to 201.

Example:
[:SOURce<hw>]:SWEep[:FREQuency]:STEP:LOGarithmic <Logarithmic>
The comman specifies the step width factor for logarithmic sweeps. The next frequency
value of a sweep is calculated (for STARt < STOP) using the following formula:
New frequency = Old frequency + STEP:LOG x Old frequency
STEP:LOG therefore gives the fraction of the old frequency. The frequency is increased
by this fraction for the next sweep step. Usually STEP:LOG is given in percent, whereby
the suffix PCT must always be used.
The command is linked to the command :SWEep[:FREQuency]:POINts for STARt <
STOP as follows:
POINts = ((log STOP - log STARt) / log STEP:LOG) + 1
If STEP:LOG changes, the value of POINTs is adjusted. The STARt and STOP value is
retained.

(With Option High Power only)
The command selects the ranges of level settings for the level sweep. The sweep is either
performed in the low level or in the high level ranges.
