Default General Radio Unit Time/Frequency Calibrator 1213-D - GRC 1213-D.jpg (1/1)

Dave, that unit looks vaguely familiar, especially the "touch point". Have
you any idea how it is used? It looks like you feed in a signal and
hetrodyme it with one of the internal reference choices. That would work for
frequency, but time 'pips' must have been sent to a 'scope' to compare with
the measured pulse stream.
GR sure turned out some 'unusual' stuff.
I really like the " move switch to start divider "; make a defect in design
into a 'feature' :-)

Anyone seen one of these? I've had it for 10 to 15 years and have never
seen another like it.
