Description
Overview
The GAOTek CATV multimeter provides services for continuously variable optical signal attenuation. It supports laser systems for online testing; therefore, they can be used in the digital system of communication devices (such as PHD, SDH) and in the system of adopting analog modulation (CATV).
Features
- Stepwise attenuating by circumgyrate dial attenuating step 0.05 dB
- Provide with the function of displaying dB and dBm attenuation value
- Alternative function of 10 minutes Auto-off without operation
- After off the system will have the memorizing of the attenuating value
