●
COM (R&S EVSG-K6) - determines signal parameters from VHF/UHF communica-
tion channels
Measurement modes with graphical results
The following measurement modes provide graphical results:
●
RF Spectrum mode (R&S EVSG-K10) - displays the power vs. frequency diagram
(spectrum) for a variable frequency range of the input signal
●
IF Spectrum mode (R&S EVSG-K10) - displays an enlarged view of the spectrum
for a fixed frequency of the input signal
●
AF Spectrum mode (R&S EVSG-K11) - displays the spectrum of a demodulated
RF signal with AM components
●
AF Time Domain mode (R&S EVSG-K12) - displays the frequency vs. time dia-
gram of the input signal, similar to an oscilloscope
Generally, each mode is configured individually. When you switch modes, the most
recently defined settings for that mode are applied.
However, graphical results can also be displayed directly from the measurement
modes with numeric results. In this case, the settings for the current mode are applied
to the graphical results.
Measurement modes with both numerical and graphical results
The following measurement modes provide both numerical and graphical results:
●
GBAS mode (R&S EVSG-K4/-K5) - displays measured and decoded information
from GBAS/SCAT-I sequences, frames, and slots, and graphical displays for indi-
vidual slots
