The Anritsu ML9001A is a single-channel digital-display optical power meter designed to ensure accuracy and linearity over a wide wavelength range for reliable optical power measurement. It supports a wide measurement level range from –100 to +20 dBm, made possible by suppression of internal reflection in the power sensors. The instrument features automatic calibration of all connected power sensors within the specified wavelength range, achieving ±5% accuracy at –23 dBm and ±0.15 dB linearity referenced to –23 dBm.

The ML9001A supports 12 modulation frequencies including 270 Hz for modulated light measurement, and is compatible with the MG9001A and MG9002A Stabilized Light Sources to form a complete optical loss test set. Its optical connector adaptor system allows rapid interchange of connector types across all power sensor ports. Internal coating on the power sensors suppresses reflected light, reducing measurement errors in both free-beam and fibre-coupled configurations.

With GPIB connectivity, the ML9001A achieves a measurement speed of 30 ms/point, cutting automated measurement time by more than 50% compared to conventional instruments. Up to 1000 data points can be stored and transferred via GPIB. The instrument can be stacked with Anritsu MG-series stabilised light sources for a compact, high-performance optical loss test set.
