I will take a look tonight when I get home, both at the manual and at the counter itself.? Mine has a male 3.5 mm connector on the 500 MHz to 26.5 GHz side.? I haven't looked inside for a couple years.? It wasn't working when I got it, but one of my friends helped me swap out cards until we found which one was bad.? We didn't look at the input section.? Good luck!? ? ? ?Jim

After a considerable search the only possible item I came up with in regards to a SMA item involves a relatively undocumented Option 006 for the 5343A which involves a input protection limiter for the 26.5 GHz input (affords protection to +39 dBm).? Given virtually no room to install this option it is unclear how it would fit between the N connector and the input to the sampler assembly U1.? I suspect that there has to be a significant change to the mounting of the sampler to move it farther back on the side rail to open a gap for the protector.
I¡¯ve never seen a 5343A with this option.
The same Option 006 can be used on the 5342A counter but cannot be used if Option 005 (frequency extension to 24 GHz) is installed.
