N8973A Noise Figure Analyzer 10 MHz to 3 GHz - 2

1. The N8974A and N8975A models have a mechanical switch fitted. This switch allows the analyzers to change between the 10 MHz to 3.0 GHz and the 3.0 GHz to 6.7 GHz frequency range on the N8974A. On the N8975A, the switch allows the change between the 10 MHz to 3.0 GHz and the 3.0 GHz to 26.5 GHz frequency range. If the current measurement frequency range crosses the 3.0 GHz point, the switch will operate. The mechanical switch has a limited number of cycles over which it is reliable. To maximize the reliable life of the switch, switching over the 3.0 GHz frequency point should be kept to a...
