Manual operation:
[:SOURce<hw>]:SWEep[:FREQuency]:SPACing <Spacing>
Selects the mode for the calculation of the frequency sweep intervals. The frequency
increases or decreases by this value at each step.
The keyword [:FREQuency] can be omitted. Then the command is SCPI-compliant.
Parameters:
<Spacing>
Example:
Manual operation:
[:SOURce<hw>]:SWEep[:FREQuency]:STEP[:LINear] <Linear>
Sets the step size for linear RF frequency sweep steps.
This parameter is related to the number of steps
FREQuency]:POINts) within the sweep range as follows:
f
STARt
freq_points = (f
If you change the step size, the number of steps changes accordingly. The sweep
range remains the same.
The keywords [:FREQuency] and [:LINear] can be omitted. The command is then
SCPI-compliant.
Parameters:
<Linear>

LINear | LOGarithmic
LINear
With the linear sweep, the step width is a fixed frequency value
which is added to the current frequency. The step width for lin-
ear sweep is entered in Hz (see
FREQuency]:STEP[:LINear]
LOGarithmic
With the logarithmic sweep, the step width is a constant fraction
of the current frequency. This fraction is added to the current fre-
quency. The logarithmic step width is entered in % (see
SOURce<hw>]:SWEep[:FREQuency]:STEP:LOGarithmic
on page 424).
