DIGIAIR PRO T2 – Description................................................................................2 1 GETTING STARTED…………………………………………………………………....3 1.1 POWER ON/OFF.................................................................................................3 1.2 POWER SUPPLY AND BATTERY......................................................................3 1.3 HOW TO USE THE METER................................................................................
1 Getting Started 1.1 Power ON/OFF To turn the unit ON, simply push the Power ON/OFF button (the unit is battery operated). The unit starts in Single channel mode, showing the signal on the meter. To turn the unit OFF, push and hold down the ON/OFF button. 1.2 Power supply and battery DIGIAIR PRO can be fed by an external power-supply through the VDC port, by an external power-source (10-18v dc, max 1A). This is useful in case that the battery goes empty during an installation.
Attenuator If the incoming signal is very strong (the bar in the thermometerscale reaches 100%) it can easily be attenuated with a push on the OK button (about -20dB). Press down the mode button again when the antenna is pointed in the right direction. This will put the meter in the Digital-mode. Hopefully, but not always, the digital readout; BER (bit error rate) and C/N (Carrier/Noise) will correspond well with the analog setting of the antenna.
The meter shows the frequency spectrum of 48-860 MHz. A marker can select a certain channel (with the “UP”, “DOWN” buttons). Signallevel (in dBuV) of that channel will be shown in the display also. - Press the OK-button and the meter will “zoom in” at the frequency which the marker is pointing at. Another push on the mode button will take the meter back to Singlechannel-mode 2. Description of functions 2.
The BER should be as low (less errors) as possible. The SNR should be as high as possible (the signal coming out of the noise as much as possible). In order not to be confusing both digital bars should be as high as they can be. Signal-level shall increase from left to right. More, very useful, digital info can be readout when pushing the “OK” button in this mode. The following display will be shown on the LCD CH = The selected channel (measured at) and frequency.
3. Menu The following menu is shown on the display when pressing down the MENU button: This is the main menu. Use the “UP”/”DOWN” buttons to scroll up and down in the menu system. Use the “OK” button to enable the selected function. 3.1 Beeper Choose Beeper On/Off in the main menu to turn the beeper (pitch tone) On or Off. It is only audible in Single channel mode. The idea is to help finding the strongest signal on the selected channel by listening to the highest pitch of the tone. 3.
4. Channel groups In this mode You can select the channels to be stored in DIGIAIR Pro´s memory. The stored channels are presented in Multi channel mode. Set up the five pages with the channels of Your choice. Do like this: A) The top value in the first bar (most to the left) is flashing when entering this setup. Step with the “UP”/”DOWN”-buttons to the channel You want to change. Press the “MODE”-button to open up the memory position. - The channel nr will start to flash faster.
