Dvb-c digital signal level meter
Summary
HT8553 Signal Level Meter is a digital/analog TV testing instrument with testing the MBR and BER function, supporting MER, BER Signal Level, Channel Power, V/A, C/N, FM, and Trunk Voltage.
It's compact size & light weight convenient for fieldwork. With Numeric keypad input, it simplifies the complex operating process.
operating range: 46 to 870MHz, without return path testing function.
operating range: 05 to 870MHz, work with Return path signal generator, it will measure the return path.
