The Anritsu MA9711A Optical Power Sensor is used with an ML9001A optical power meter. Specifications. Wavelength range: 0.75 to 1.8 µm. Element: Ge photodiode. Active area diameter: 5 mm. Optical power measurement range Continuous light (At 1.31 µm): -40 to +10 dBm (0.1 µW to 10 mW). Optical power measurement range Modulated light (At 1.31 µm, 270 Hz): -60 to +7 dBm (1 nW to 5 mW). Absolute Measurement accuracy (-23 dBm) for wavelengths other than 1.3 µm, specified at 23° ±5°C: ±5% (0.95 to 1.5 µm). Measurement accuracy linearity continuous light: 23°C, -23 dBm as reference: ±0.15 dB, (±0.45 dB for - 40 to -30 dBm). Resolution: W, W (REL) display: 0.1 to 1 %, dBm display: 0.01 dB, dB (REL) display: 0.001 dB.
