Follow the instructions in this chapter to perform your first measurement with the
R&S ETL.
For an expanded selection of measurement examples and background information,
refer to the user manual or the help.
The chosen example applies to the DVBC and J.83/A/C TV standard. It gives an over-
view of the active measurement channel. All parameters are set according to the mod-
ulation standard, referenced in the channel table or by the default digital TV modulation
standard. The spectrum is displayed in a full screen trace.

Use a digital TV generator as signal source (e.g. R&S BTC).
1. Connect the generator directly to the R&S ETL.
2. Set the TV generator to the following parameters:
a) Center frequency: 100 MHz
b) Single carrier 64QAM modulation
c) Root raised cosine transmit filter with a roll-off factor of 0.15
d) Symbol rate: 6.9 MSymbols/s
