GQ-1129/1129D Signal level meter The instrument adopts the all-number display, the readings on the measuring instrument are clear and precise, and owing to the introduction of the micro processing unit, therefore, it makes its functions stronger, the precision higher, operation more flexible and convenient. The large screen figure monitor is very convenient to measure the main technical targets of CATV system. It has the functions such as the single-channel, multi-channel, all-band scanning, difference-carrying measurement, signal-to-noise ratio (SNR, S/N) measurement and spectrum analysis frequency analysis etc.
