stops a sweep when this input is pulled

low. Retrace does not occur, and the sweep resumes when this input
is pulled high. The open circuit voltage is TTL high and is internally
pulled low when the synthesizer stops its sweep. Externally forcing

this input high will not cause damage or disrupt normal operation.

activated on a TTL rising edge. Used to

externally initiate an analog sweep or to advance to the next point of
a step list or a frequency list.

Produces a 1

points evenly spaced across an analog sweep, or at each point in a
step list or a frequency list.

supplies a voltage that is proportional to the RF

output frequency, with a ratio of 0.5 volt output for every 1 

 of

RF frequency (factory setting). This ratio is switchable to either
0.25 or 1 volt. The switch is located on the 

 SYTM assembly, see

pulse when the RF output is coincident with a marker frequency.
