[Test-Equipment] wiltron 560A ???

[J. Forster]

The mainframe is a basic Tek 5000 series, perhaps a bit modified. The PI is a 3 wide unit.

> I'm not familiar with the Wiltron line-up, but that looks like it's only a digital-storage and signal-processing mainframe meant for use with external signal sources and detectors.  It would not be useful as-is, and if it's designed only for scalar network analysis, it would not be useful as a general-purpose spectrum analyzer in any event.
