The Anritsu ML9001A is a single-channel digital-display optical power meter. It insures accuracy and linearity over a wide wavelength range and greatly improves measurement reliability. It also has an improved basic performance, measurement can be made over the wide level range from –100 to +20 dBm because internal reflection in the power sensors has been suppressed. The ML9001A accurately and automatically calibrates all the power sensors within the specified wavelength range and ensures a ±5% accuracy at –23 dBm. It also has a ±0.15 dB linearity (–23 dBm reference value). The ML9001A extends the guaranteed accuracy range of the measured values and enables high-accuracy measurement. Specifications. Frequency range: 380 to 1800 nm (sensor dependent). Optical power measurement range: -100 to +23 dBm (sensor dependent). Display: 4 digit, W, W(REL), dBm, dB(REL) selectable. Calibration coefficient: Adjustable. Recorder output: 1 V/full-scale, linear output. Range select: Manual selection and automatic ranging. Measurement mode: Continuous and modulated light. Wavelength sensitivity correction: Automatic correction in 1 nm steps. Data memory: Max. 1000 data via GPIB.
