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.
Parameters:
<Logarithmic> float
Range:
0.01 to 139 dB
Increment: 0.01 dB
*RST:
1
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<hw>]:SWEep:RESet[:ALL]
The command resets all active sweeps to the starting point.
Example: SWE:RES
resets all active sweeps to the starting point.
7.13 STATus Subsystem
This system contains the commands for the status reporting system.
​
*RST
​
on page 208 has no effect on the status registers.
Queries return the current value of the respective register, which permits a check of the
device status. A decimal value between 0 and 32767 (=2
15
-1) is returned.
The configuration commands set the respective register thus determining which status
changes of the R&S SMC causes the status registers to be changed. A decimal value
between 0 and 32767 (= 2
15 -1) is set.
