GM rf attenuators 3453H-605, MAX Atten 2GHz to 4GHz, tested

exact item shown, the analyzer traces show freq response out to 3 GHz and different attenuation setttings. tests were run wtih 12VDC (plus and minus) excitation. I put the connection information as the last photo, it would be good for you to read the data sheet before using it to understand how it works. note to me: computer hutch, top shelf behind door the data sheet for a simiar item is here, but this is an older model that does not use a data strobe, just ground the leads you want to activate. the H generally means high speed, there are three wires with stripped ends, hook the green one to neutral, the blue one to +12 and the purple one to -12. https://www.kratosmed.com/gmcatalog/microwave-attenuators/series-349-and-349h-octave-band-11-bit-digital-pin-diode-attenuators
