Anolog and Digital TV Signal Level Meter
Model NO:JZH-36EA
Product Description:
Digital TV signal system can accurately detect and measure anolog signal, it features super long power supply and is very suitable for trunk line network maintenance as well as maintenance carried out by client. Excellent cost performance is as its leading feature.
Main Features:
* One key change between frequency and channel, easily during operating;
* Accurate QAM performance index ---Average power, MER, BER.
* Support many kinds of DVB mode---16/32/64/128/256 QAM.
* Wide bit rate setting:1MS/S~7MS/S.
* Built-in TV Channel List--- Fit for any network detecting.
* All around anolog TV index detecting---Level, V/A, C/N; slope and trunk line.
* Quick charging enables trouble-free operation more than six hours.
