Smith Chart Plotter
 

I'm trying to get some info on a Smith Chart Plotter made by Dielectric
Products Engineering. It looks like an RF bridge with an input, load and 4
bnc outputs for +/-X and +/-Y-axis. Would appreciate any info.

Don't know about that particular instrument, but it might be
enlightening if you're not already aware, that the Smith chart is
simply a linear plot of the complex reflection coefficient, which is
pretty easy to get from an RF bridge. The chart overlays that linear
plot with the circular grid lines for resistance and reactance (and
conductance and admittance and various other things as desired).

Cheers,
Tom
