I have a 610D sweeper here somewhere with a couple of plug-ins. No time
to look now and I'll be away for a couple days. If you don't get better
info before that, I may be able to dig more info. Got some docs here but
they may be on microfische -- yuck.

Nice basic sweeper for microwave bands with appropriate plug-ins. As I
recall, there was nothing frequency accurate in it. I think there was an
option in the mainframe for a crystal source to generate marker
multiples. This may be similar to what you have. My recollection is it
was low freq, maybe 1 or 5 MHz, and very low quality
stability/accuracy-wise. Just a ballpark reference to generate marker
