Hello All,
I’m a new member here, thanks for letting me join.
I am looking for any servicing instructions and schematics for my Thandar TSA250 spectrum analyser adaptor. Any help would be greatly appreciated.

@raymk41 Have you tried TTi themselves first? I have one of each of those units. Is yours faulty or are you just curious?

Thank you for your reply. I think I briefly exceeded the maximum input specification. I accidentally applied a 5 volt peak to peak sine wave at 1 mHz. I can’t get the unit to respond to any input signal.
I didn’t realise that TTi were still in business. I will try to contact them directly.
Best Regards
Ray Beckett
