Connector (Out / In)
Selects the output connector. The input connector depends on the output connector
and is displayed for information.
The DIG IQ connectors are located at the rear panel (if an I/Q board is installed).
Remote command:
ROUTe:CDMA:SIGN<i>:SCENario:SCFading[:EXTernal]
Sample Rate (Out / In)
The used sample rate is displayed for information. The value of 100 Msps is fixed.
Configure the connected instrument accordingly (baseband input settings and digital
I/Q output settings).
Baseband PEP (Out / In)
Indicates the peak envelope power of the baseband signal as dB value relative to full
scale. "Full scale" in this case corresponds to the maximum representable amplitude of
the I/Q samples.
Use the displayed output PEP value to configure the baseband input of the
R&S
AMU200A.
Configure the input PEP so that it matches the baseband output of the connected
instrument.
Remote command:
CONFigure:CDMA:SIGN<i>:IQIN:PATH<n>
Crest Factor (Out)
Indicates the crest factor of the baseband signal, i.e. the ratio of peak to average base-
band power. The average power is calculated for time intervals with active forward link
traffic channel timeslots only.
Use the displayed crest factor value to configure the baseband input of the connected
instrument.
Baseband Level (In)
Indicates the nominal RMS level of the baseband signal during a call (connection
established).
Configure the baseband level so that it matches the baseband output of the connected
instrument.
Remote command:
CONFigure:CDMA:SIGN<i>:IQIN:PATH<n>
4.3.6 Internal Fading
This branch of the configuration tree is only visible if a fading scenario is selected
("Standard Cell Fading") and the fading source is set to "Internal".
