[: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>
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 linear sweep is entered in Hz (see [:SOURce<hw>]:SWEep[: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 frequency. The logarithmic step width is entered in % (see [:SOURce<hw>]:SWEep[:FREQuency]:STEP:LOGarithmic).

*RST:LINear
Example: SWE:SPAC LIN

selects linear sweep spacing for a frequency sweep at the RF output.

Manual operation: See "Spacing - Frequency Sweep"
