The 

Spectrum-mode

 is accessed with another push on the MODE button

The meter shows all channels like a spectrum. A marker can select a certain channel (with the 

“UP”, “DOWN” buttons). Signallevel of that channel will be shown in the display also.

Another push on the mode button will take the meter back to Singlechannel-mode

2. Description of functions 

2.1 Single channel-mode (view one channel)

In this mode the meter measure analog signal strength on the selected channel. The 

higher dB value, the better signal. The maximum signal received is also indicated. To 

change the channel, use the UP /DOWN buttons. 

The battery indicator is not shown when the unit is fed by an external power-supply 

2.2 Digital-mode (view digital) 

BER (Bit Error Rate) and MER (Modulation Error Ratio) is presented in this mode.

The BER should be as low (less errors) as possible. The MER should be as high as possible 

(the signal coming out of the noise as much as possible).

2.3 Multi channel-mode (view six channels)

In this mode the meter measure the signal strength of six individually selected 

channels. DIGIAIR Pro CATV can be set up with five such pages of six channels (5x6 

channels). The page number is indicated in the top-right corner. To scroll through the 

pages use the UP/DOWN buttons. To show/hide the channel numbers use the OK 

button. Also, here the difference (Tilt) between the highest and the lowest channel can 

be viewed. The max-peak values are reset when changing page.
