[Test-Equipment] GR 1800A VTVM

[Barry]

Anyone familiar with the GR 1800A?  I just got one and am a bit baffled by the probe accessories.  The manual displays them as they are disassembled and has a brief discussion of them, but there aren't any diagrams showing how they're supposed to be assembled.

I think they're designed to form various configurations, but I just don't see how they're supposed to fit together.  I can see that the banana plug unscrews from the center of the probe and apparently one can replace the male plug with the female adapter.  Other than that, I don't see how the larger rings or the 50-ohm terminator fit together, etc.

Hopefully someone knows about these and can direct me a bit.

Thanks,
