[R-390] Sweep Generator Alignment

[Jim Brannigan]

A sweep generator is used in conjunction with an oscilloscope to display
amplitude vs. frequency.  It will present a "picture" of the shape of a
tuned circuit.
The sweep generator is connected to the input of the device under test and
the O-scope to the output (through a demodulator).  The sweep generator is
also connected to the Horizontal input of the scope.

They are commonly used to align fixed tuned circuits, like the 455kc. IF(or
TV IF).   I don't know how useful a 4Mhz. generator would be since the
signal will have to pass through the entire receiver and this would not
present a valid "picture" of the IF.
If the price is right they are fun to play with.
