Does anyone have any experience with Spirent Communications TAS 4500 (TAS4500) RF Channel Emulator.
Specifically, I want to know what is inside. I am interested in the built-in local oscillator, attenuator and RF 25~3000MHz front end. Pictures would be fantastic. Want to know if anything could be repurposed (PXI, PXIe, Compact PCI, Etc) or if it is all custom boards.
Cheers!
