Hi all

I inherited an old function generator (Tristat Electronics FGC001) from another ham (W7OSP SK). I know enough to be able to use it, but I have no idea what some of the knobs on here do. I can't find a manual (or any specs) for this particular model online. Does anyone know what these knobs do or can someone direct me to a manual?

The controls I'm wondering about are:

Sweep: Lin/Log and Ext/Int (1st and 2nd knobs from the left)
Pulse: TTL -> CMOS (4th knob from the left)

Also I don't know how to work the frequency counter, which would be nice to have.

Thanks

Cory, similar to many function generators of the era,
Search the heathkit, Exact, Wavetek in 1970-1990
This one seems like a copy of one of those.

The pulse TTL, TTL logic levels, low sinks a few mA, high 3V CMOS 0, 5V
Check a wiki for logic families

Sweep
lin- freq increasing at fixed hZ per unit time, Log, logarithmic increasing freq with time.
Similar to spectrum or network analyzer sweep

Counter is off in some control settings.

Just play around
