[Test-Equipment] General Radio module

[Fuqua, Bill L]

This is one of the most interesting of all GR equipment.
It was the grandfather of the DDS synthsizers in a since, but it was a DAS 
Direct Analog Synthesizer. Similar to the ones made today by PTS.
They did not use the frequency divider chips we used later on but
used multivibrators and phase locked loops to achieve the same results.

Almost certainly from the Type 1160 series of frequency synthesizers, ca. 1968.
