Rohde & Schwarz YIG preselection for 26.5 GHz-models additional to filter banks, only for RF input A, HW option
The Rohde & Schwarz YIG preselection option (part number 1347.5443.26) is a hardware upgrade designed specifically for FSW signal and spectrum analyzers with a frequency range up to 26.5 GHz. This option adds a YIG-tuned preselector to the analyzer, supplementing the existing filter banks and providing enhanced out-of-band signal rejection. It is installed exclusively on RF input A and is intended to improve measurement accuracy by reducing the influence of image frequencies and spurious signals. The YIG preselection is particularly beneficial for applications requiring high dynamic range and low noise floor in challenging RF environments. This hardware option is only compatible with 26.5 GHz models and must be specified at the time of order or installed by authorized service personnel.
