Elva-1 specially designed GPS synchronized mm-wave frequency meter GPSFC-xx series. This solution allows to provide independent frequency measurement in different laboratories with absolute accuracy.

Block-diagram of the frequency meter

Millimeter-wave frequency meter GPSFC-xx series can be designed for operation in 26-170 GHz frequency range. Frequency window 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:
