Digital TV-signal level meter TELEMANN 1500

8
Manufacturer:
Range:

 

The device allows measuring the level of analog and power of digital signals and signal-to-noise ratio (S/N) for the analog and digital signals. The device can also be used to measure the frequency spectrum and the spectrum of channels and analyze AFC. The signal level sound indication function will be useful for antenna positioning. It is also possible to load from/to the PC the plans of channels and a data log (option 1500D).
Screenshots of the main measuring modes of the device are presented in the figures below :
