Graphic representation MER/Carrier

Mer/Carrier function represents MER value for each carrier of DVB-T signal. This is pretty useful to detect if there is any interference inside the channel that makes the quality signal to get worse and that is invisible for a traditional spectral analysis.

Apart form the graphical representation of the MER dependence from carrier, other useful information is presented on the screen:

• MER RMS: Average MER of the DVB-T signal.
• MER Max: Maximum MER value of the DVB-T signal (number of carrier with this maximum value of MER).
• MER Min: Minimum MER value of the DVB-T signal (numer of carrier with this minimum value of MER).
• MER: Mer value of the selected carrier.

ZOOM Mer/Carrier

Avaliable span values are the following:

• ZOOM 8K: Full, 3200, 1600, 800 and 400.
• ZOOM 2K: Full, 1600, 1200, 800 and 400.

Central Carrier

In order to select the central carrier CENT. CARR. menu function must be used. It will appear a list showing the available options for this parameter:

• Select: Option to modify the central carrier manually using the rotative selector.
• Central: Option to select the DVB-T standard central carrier as the representation central carrier (8K mode, central carrier 3405; 2K mode, central carrier 853).
• Mark: Option to select the mark position as the central carrier,
• Ma ximum: Option to select the carrier with maximum MER as the central carrier.
• Minimum: Option to select the carrier with minimum MER as the central carrier,
• Other: Option to modify the central carrier manually using the numeric keyboard.

Measured Carrier

In order to select the measured carrier MEAS. CARR. menu function must be used. It will appear a list showing the available options for this parameter:

• Select: Option to modify the measured carrier manually using the rotative selector.
• Central: Option to select the DVB-T standard central carrier as the measured carrier.
• Maximum: Option to select the carrier with the maximum MER as the measured carrier.
• Minimum: Option to select the carrier with the minimum MER as the measured carrier.
• Other: Option to modify the measured carrier manually using the numeric keyboard.
