dB-Meter

dB Meter DB

The dB-Meter measures power stability and power changes across a wide dynamic range with high accuracy and high speed. A fiber coupled stabilized 1.55µm laser diode is built in for quick and easy testing of passive components or local fiber loops. Alternatively light of external sources within a wavelength range of 780nm-1650nm can be used.

The test signal is provided both through an analog interface (0V–3V) and serial (USB) interface in a digital way. The measurement value is provided on command (“pull”), in fixed time intervals (“push”) or self-triggered on a pre-defined level.

No extra power supply is needed when connecting the USB-interface.
