VF-5
Improve your testing accuracy on both forward and return paths.
The only preselector that offers filters for testing on both the return and forward paths, Trilithic’s VF-5 Tunable Preselector Filter allows you to improve the accuracy of your measurement of composite triple beat, cross modulation and other spurious signals in a working CATV system.
The VF-5 combines six precision fixed filters for return path preselection and four tunable filters for 55-880 MHz range testing, offering the versatility technicians need for the most demanding CATV applications.
The VF-5 filter blocks illegitimate signals – which spectrum analyzers and signal level meters can generate because of input overload – and passes only the carrier to be analyzed to the instrument's input. As a result, the VF-5 can improve an instrument's reliable measurement range by as much as 30 dB.
