fonograph:
How many extra bits can you get in high res mode? 2? 6??  Can you set how many extra bits you get or is it automatic? Like can I decide if I halve the samplerate for aditional half bit or 4096x lower samplerate for 6 extra bits

Hi fonograph - you can get up to 16-bits (so 6 additional).  It is handled automatically.

Hi Rich,

I know you're a scope guy but would it be possible for you to help in locating the full service manual to the SMIQ series RF Vector Sig Gens?
All we can find is a service manual that is missing the schematics and part placements.   we would be extremely helpfull to those of us picking them up on ebay.  Most seem to have ALC or level problems so even it is was the IQCON and IQMOD boards that would help so much.

understand if it's not you area and can't help but thought I would ask?

Hi Rich,

Not sure if you can help me out here or not but I have been advised that I should at least ask you so here goes.

I have just aquired a Hameg HM 408-1A storage scope which has a few problems to sort out electronically, but they can wait until I see if I can fix other more important issues with the mechanics, no point in resolving the electronics if I can't control the thing is there?

Can you advise me as to where I might be able to source the nylon flexible couplings that sit between the Intensity, Focus, Readout Focus and the Volts / Division controls and the knobs? I also could do with but not essential, are the grey key caps for the Y Pos I and Y Position II, just the push in caps?

There is a thread open regarding this restoration here  https://www.eevblog.com/forum/testgear/hameg-408-1a/ which has a photo of the flexible couplings in question.

I'll understand if you can't help, but like I said, you was recommended to me as your company took over Hameg.
