The MN4765B is a characterized, unamplified photodiode module. It is used as an optical receiver with the Anritsu MS464xB and MS4652xB Series VNAs to perform highly accurate and stable optoelectronic measurements of both modulators (E/O) and photoreceivers (O/E). Bandwidth and wavelength coverage depends on the option selected when the module is ordered.
The test signal from the MN4765B RF connector is then fed back to the test port of the MS464xB VNA for further signal processing. In the MS4640B Series Microwave Vector Network Analyzer Maintenance Manual - Note 10410-00320, refer to Chapter 2 - Theory of Operation for signal processing details.
