R&S FSL Cable TV Measurements (Option K20)

Fig. 2-70 Carriers measurement using a Channel Table. No input signal!
8. Press the Channel No softkey.
9. Input a channel number via the numeric keyboard. The Cable TV Measurements option will only
allow analog TV channels defined in the active channel table, since we are in a measurement for
analog TV channels and digital TV signals would not make sense! The same is true when you use
the rotary knob for changing the measurement channel.
So, the very small example channel table only allows us to switch to channel 22. Observe how the
RF frequency changes.
10. Press the MEAS key.
11. Press the Digital TV softkey.
This switches to measurements for Digital TV signals.
12. Press the Spectrum softkey.
The resulting measurement is displayed (see Fig. 2-71).
The Cable TV Measurements option once again configures the measurement automatically and
gives you information about the channel borders and the modulation standard.
