Interstate Electronics Log-Linear Sweep Generator

[jordheis]

Hello,
Anyone have experience with this Interstate Electronics F77 Log-Linear Sweep Generator? Whether or not you have direct experience, would you see this as a useful standalone piece of equipment to have in the stable for testing purposes?
I cannot find a manual or discussion on it so am curious to know more.
0.001Hz-20MHz, am/fm/sine/tri/sq/pulse

Thanks for your consideration.

An externally hosted image should be here but it was not working when we last tested it.

I've used these at work long ago and think they're excellent, though not too well known. The low frequency capability is unusual; I'm not sure how useful it is for audio purposes. Manuals and schematics can be near impossible to find. If it works and if you can get documentation, I'd say it's a good addition to the bench. They also made a similar and very useful pulse generator with variable rise and fall times.

Thanks much for the response. I am trying to find an adequate function generator and have been looking at this F77 as well as the HP 3312A.

It looks like a pretty rockin' function generator to me. I like the pulse function. That can come in handy.

The HP 3312A is a nice one too. I use mine frequently. I picked it up on ePay for around $100.
