Make current flow out from pin 40 and measure the flow
current when the burst gate pulse is not found at pin 12.
Measure the output frequency at pin 13 when no signal is
input.
Change the frequency of SGc and measure the frequency at
the moment when the output signal at pin 13 and the input
signal at pin 40 are pulled in. The horizontal pull-in range is
measured by comparing with the horizontal free run
frequency.
