EMULATED “COFDM” DIGITAL TV MEASUREMENT
The COFDM measurement can be demodulated or emulated by selecting this mode from the configuration menu (see “Configuration Menu” section on page 12).
How to reach this measurement:
DIRECT = From any previously stored “PLAN" and COFDM "PRG" you are already in COFDM (digital terrestrial TV).
NAVIGATION = Press ruotate the encoder select then navigate in the parameters at the top of the screen,
which can be reached using the appropriate keys, or by rotating the encoder press to confirm the selection.
N.B. Emulated OFDM measurement.
- use C/N far (f) when there are adjacent
channels
- use C/N near (n) when there are no
adjacent channels
- in the case of selective conversion
head-ends, use only C/N near (n). In
some cases C/N far (f) could measure a
C/N which is too high.
(See Configuration menu on p. 12).
