Description
Overview
GAOTek Signal level meter is a digital or 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 is compact size and light weight convenient for field work, with numeric keypad input, it simplifies the complex operating process. Signal level meter operating range: 46 to 870 MHz, without return path testing function. The signal level meter operating range 5 to 870 MHz works with a return path signal generator, it will measure the return path.
Features
- Support QAM 32 64 128 or ITU-TJ.83 Annex A or B or C
- Analog, Digital and Dual channel measurement
- MER, BER. A or V, C or N average power, trunk line voltage
