Default Exact Model 7030 Function Generator - Info sought

As part of a scope buy, I have aquired one ancient function generator labeled 'Exact Model 7030 Generator'. The unit is in need of some TLC.......... or a ride to the dump

Especially the features for 'DC offset' and 'Symetry' seems to be faulty (severe signal distorsion).

Does anyone have any information on this this unit (Or ancient Exact units in general):

- Age?
- Manuals (User/technical/repair) ??
- Schematic ???
(- Known problems ????)

Any information is much appreciated

The Exact Generators are very high quality and the one you have should be good to 10 MHz or better. There are sevveral on-line manual dealers, that can be found through this: http://www.big-list.com/usedmanu.html I would make the effort to fix it. A replacement of similar capabilities would not be cheap.

Default Just bought a 7030

Just found this old post, I just bought an Exact 7030 on Ebay, as part of a lot with a Wavetek. The seller claimed to be unsure whether either worked, well long story short the Wavetek worked, but the 7030 did not. Did you ever have sucess with yours?

Old post indeed - had actually forgotten about it.... alias no one has been able to suggest or find any-thing.

Are however still interested in any information anyone may be able to provide any information - so please pass on anything you stumble upon...

(Confession: A have a week spot for the old mechanically well constructed equipment - far from the 80$ plastic ELV function generator I bought as replacement.)

The thread just just got older, I have one, I replaced a defective bridge rectifier, a dried out filter cap, and a bad npn transistor in the negative 24V supply.
Now it has an output signal, but only above the 100kHz setting but not below.

So I'm looking for info on the Exact 7030 waveform generator. I will add,
I've looked several times in the last 16 years.
Thanks, Mikek

It's been found!!!! I got help on a Newsgroup.
The first thing I found was part 1 of the instruction manual, but with no schematics: http://forum.arduino.cc/index.php?ac...0;attach=69874 and part 2 of the manual at http://forum.arduino.cc/index.php?ac...0;attach=69875 . With schematics and parts list.

Many thanks to Matt Roberds.
