The 771RH (single channel), 772RH (dual channel) and 773RH (triple channel) optical power meters are designed for testing DWDM transmission systems, CATV systems, and high-power output devices such as EDFA amplifiers and pump lasers. Based on a 2-mm InGaAs photodetector, the power meters offer a measurement range from +27 to -60 dBm. The power meters provide measurement speed and resolution of 0.001 for logarithmic dB and linear (W) units. All of the units can be installed in a standard 19-in. rack with a 700R controller module. GPIB interface is a standard feature. A comprehensive application software package is optional. The 771RH, 772RH, and 773RH are available at $2050, $3075, and $3795, respectively.
