Description
Overview
GAOTek CATV Attenuator supports use for continuously variable optical signal attenuation. It provides a laser system for on-line testing; therefore, this product 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 circumgyrated dial: attenuating step 0.05 dB
- Provide with the function of displaying dB and dBm attenuating value
- 10 minutes auto-off, activated and deactivated with keypad
- Memorizes attenuating value and step after instrument shutdown
- Restores to previous state when the instrument is reopened
