Anritsu ML910A 2 Channel Optical Power Meter

The ML910 optical power meter provides two independent channels and advanced functions, enabling a variety of sophisticated optical-power measurements. Seven types of optical sensors are available to suit a variety of applications (any two can be connected as required). The two channels are completely independent, and have separate displays, providing the same versatility that previously required two meters. Processing between channels is also possible. If a feed-through sensor is used, fluctuations in the output level of the optical source can be canceled, enabling exceptionally precise relative measurements with a resolution down to 0.001 dB. Wavelengths from 0.38 to 1.8 mm can be measured, with sensitivity down to -90 dBm at 1.3 mm. The optical sensors have a built-in ability to respond to any wavelength in their specified range, so direct readout of the absolute optical power is possible simply by specifying the wavelength. A simple change in connections permits uncompensated measurements as well. The data-storage function of the ML910B enables up to 3,000 measured values to be stored at the touch of a button, which greatly simplifies work in the field. An internal display calibration circuit.
