[Premium-Rx] Racal 6793A noise

[Jeff Anderson]

I was recently comparing the performance of my Racal 6793A to my Racal 6790A, and I noticed that the 6793A was noticably noisier than the 6790A.

I'm not sure what the problem is (yet).  The 6793A seemed a bit less sensitive, so it may  just be that it needs an alignment to bring up the signal level with respect to internal noise.

Another possibility is that the synthesizer is noisier in the 6793A.

But before I dig into it, I was wondering...

o  Has anyone compared the 6790A to the 6793A?  If so, what were the results?

o  Does anyone have an alignment procedure for either the 6790A or the 6793A?

Thanks!
