RF Section Troubleshooting (RF/Microwave Analyzers)
RF Section Description
The RF section is comprised of the following major assemblies:
— A9 Input Attenuator A
— A10 Input Attenuator B
— A11 Low Band Switch Assembly
— A12 YTF Preselector
— A14 L.O. Synthesizer Assembly
— A13 RF Front End Assembly
— A15 Front End Control Assembly
— SW1 and SW2 - Option MPB Microwave Preselector Bypass
SW1 and SW2 and their associated cables are the microwave preselector bypass hardware. This
hardware is present in analyzers containing any or all of the following three options:
However, if there is no license for option MPB, the hardware will default to the non-bypassed
path (high band microwave signals will be routed through the A12 YTF Preselector). If a license
for Option MPB is present, it will be possible to bypass the A12 YTF Preselector.
