The instrument is provided with a 4.5" B/W-monitor which either shows normal TV-channel, the frequency spectrum 2-2150 MHz (or parts thereof) alt. Digital data. Menus/help displays are shown on the LCD-screen (64x128) beside the monitor.
Both analog SAT-TV and CATV channels can be tuned in and viewed upon. The COMBOLOOK is able to work with the return-path signals in Cable-TV networks (5-65 MHz). according to the EN50083 standard. The TV-part presents the full range spectrum of 2-900 MHz which can be zoomed into smaller parts (min 13 MHz-span). The TV-part is very sensitive and accurate. It presents signals ±1dB (at +20 C). The SAT-part also has very high resolution and accuracy.
It presents measured data ±2 dB (at 20 C). The Sat-TV spectrum can be expanded (zoom in) for correct adjustment of the polarization (“cross-polarization”). The SAT- part presents, under one of the sub menus, digital information like BER (bit error rate), constellation-diagram (QPSK) and S/N (signal/noise ratio). The NIT function of the SAT-part can identify the various TV-satellites by reading out the NIT in the Bitstream (NIT = Network Information Table). The NIT also contains info about the transponders TV and Radio channels. COMBOLOOK can handle a lot of memory-positions and both spectrum-pictures and certain frequencies can be saved (both analog and digital transponders). The power of the instrument is supplied by a built in and rechargeable battery.
