R&S SMB100A
Manual operation:
[:SOURce<hw>]:SWEep:POWer:SPACing:MODE?
Queries the sweep spacing mode. The sweep spacing for level sweeps is always lin-
ear.
Return values:
<Mode>
Example:
Usage:
[:SOURce<hw>]:SWEep:POWer:STEP[:LOGarithmic] <Logarithmic>
Sets a logarithmically determined sweep step size for the RF level sweep. It is
expressed in decibels and you must enter the value and the unit dB with the command.
The level is increased by a logarithmically calculated fraction of the current level
according to:
step_size
Level
with Level
sweep steps
This parameter correlates with the number of steps
range as follows:
level_points = ((Level
If you change the step size, the number of steps changes accordingly. The sweep
range remains the same.
Parameters:
<Logarithmic>
