Command Description R&S SMC100A

[SOURce:]SWEep:POWer:STEP[:LOGarithmic] 0.01 ... 165 dB
The command sets the step width factor for logarithmic sweeps. The next level value of a sweep is
calculated (for STARt < STOP) using the following formula:
New level = Old level + STEP:LOG x Old level
STEP:LOG therefore gives the fraction of the old level. The level is increased by this fraction for the
next sweep step. Usually STEP:LOG is given in decibels, whereby the suffix dB must always be
used.
The command is linked to the command :SWEep:POWer:POINts for STARt < STOP as follows:
POINts = ((STOP - STARt) / STEP:LOG) + 1
If STEP:LOG changes, the value of POINTs is adjusted. The STARt and STOP value is retained.
Example:
SWE:POW:STEP 10dB
'sets the step width for logarithmic sweep spacing to 10 dB of the previous
level in each instance (for a level sweep).

[SOURce:]SWEep:RESet[:ALL]
The command resets all active sweeps to the starting point.
The command triggers an event and therefore has no reset value.
Example:

'resets all active sweeps to the starting point.
