Mm-wave frequency meter GPSFC-xx series can be designed for operation in 26-170GHz frequency range. Frequency window analyze for one frequency point of reference synthesizer 12-18 GHz is (Fr x N)+/-0.1 GHz. By switching the reference synthesizer user could cover all desired frequency band. User control and output interfaces could be adapted according to customer’s specification.

 As an example below specification for GPSFC-94/0.1 with analog output is presented:
