The Anritsu MS9720A is an optical spectrum analyzer with a diffraction grating that is used to measure and analyze optical spectra in the 1450 to 1650 nm band for WDM communications systems. A wavelength accuracy of ±20 pm is achieved over a range of 1530 to 1570 nm by performing calibration using the built-in wavelength reference light source. The MS9720A noise level is -87 dBm, so the tester is ideal for measuring the SNR of light sources used in WDM systems, as well as optical leakage and reflected light.
