Batboard

Hi Everyone
I was wondering if anyone could help me.. I have just purchased a used 2975 and it appears to be very weak on the RF generator,no signal until - 67 dBm I do have full stable RF from the generator module itself but it drops level when it the main block assembly where the TR / GEN & ANT sockets are, it appears it maybe the HMC347 switch but I cant seem to find them anywhere, the other option is would anyone have a spare module they would sell or know someone that may have one from a scraped unit ?

Thanks for your time

I have confirmed it is in the module... so if anyone would have a 7005-4242-500 module please let me know... thanks again for your help

HI twbtech, Those modules are difficult to find at best. We've had good success repairing them if you're interested. We would need the entire monitor so we can confirm that it meets spec in your instrument after repairs.
Thanks
