Arguments are as follows:
• FreqStart = Sweep Start Frequency expressed in Hz
•
FreqStop = Sweep Stop Frequency expressed in Hz
•
FreqStep = Sweep Step Frequency expressed in Hz
o
If FreqStep > 0 then a standard sweep, tuned step by step, is
made
o
If FreqStep < 0 (typical = -1) then the step will be set to AUTO
o
If FreqStep = 0 then the sweep will be made by tuning all the
frequencies which are listed in Frequency-Scan-Tab (which it
must have been written previously by command
SSFW .
• Detector . In non –smart mode , any combination of the following
detectors can be used and combined. All the detectors set will be
measured and sent out. However, in
Smart Mode only one detector at
time, in addition to PEAK which is always present, can be set.
o
Non Smart Mode (All detectors can be indicated at once). Order is
not important.
 P  Peak
 Q Peak
 N C-Rms
 A  Avg
 R  Rms
 C  C-Avg
o
Smart Mode (No more than 2 detectors can be indicated at once)
 S  Smart Mode (this must be the first in the string)
 Q Peak

N C-Rms
 A  Avg

R

Rms
 C  C-Avg
• HoldTime = Hold Time for each step and it is expressed in ms. Note that
in case of Smart Mode HoldTime is used only when the disturbance is
measured again by the alternative detector as minimum time, depending
on the Rbw set, is used for the fast scan.
• Rbw . This is the index of Rbw to be used for the scan. Neither automatic
selection, nor automatic switch is performed. The user must issue a
suitable Rbw index. Index are as follows:
o
1

300kHz
o
2  100kHz
o
3  30kHz
o
4  10kHz
o
5  3kHz
