Noise Figure Analyzers NFA Series
The N8974A and N8975A NFA models have a mechanical switch fitted to allow them to switch between the 10MHz to 3.0 GHz frequency range and the 3.0 GHz to 6.7 GHz and the 3.0 GHz to 26.5 GHz frequency ranges respectively. If the frequency range you are working in crosses the 3.0 GHz point, the mechanical switch operates. The mechanical switch has a limited number of cycles over which it is reliable.
To maximize the switches reliable life, switching over the 3.0 GHz switch should be limited where possible.
