Multi-channel Signal Generator

R: V20150828-21-39 Data sheet  

 

Outline  

The DSG9903 multi-channel signal generator is the latest product developed by our company. The product is combined via 106 different frequency points and outputted via electrical attenuation. The frequency output range is from 48-860 MHz and the output level is not less than 94dBmV. And the rack system is mainly used for testing the main specifications of C/N, C/CTB, C/CSO in HFC of CATV, also used for testing the specifications of optical transmitters, optical receiver and amplifier etc. Therefore, it is mainly applied in metering center, CATV station, and CATV equipment manufacturing factory.

Features

  • Having RF auto-stable electrical level in order make the electrical level more stable
  • With unique circuit design and also with good specifications of C/N, C/CTB, C/CSO
  • Adopting unique lock phase technology, has small carrier phase jilter, low noise and small frequency deviation
  • Applied to test the main specifications in the optical link of CATV HFC
  • Applied to test the main specifications of optical transmitter, optical receiver and amplifier
  • With independent power supply, beautiful appearance and convenient use
