C-6 Operating and Programming Reference
frequency to +lO V at the specified maximum frequency, with a
proportional voltage for frequencies between the specified minimum
and maximum. When the swept signal generator is in manual sweep
operation the sweep output voltage is a percentage of the span.
Minimum load impedance is 3 kR.
STOP SWEEP IN/OUT
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 swept signal generator stops its sweep.
Externally forcing this input high will not cause damage or disrupt
normal operation.
10 MHz REF INPUT
reference signal for operation referenced to an external time base.
Nominal input impedance is 50 CR.
10 MHz REF OUTPUT
from the internal frequency standard of the swept signal generator.
This input is a 50 fl connector that can be used as the master clock
reference output for a network of instruments.
TRIGGER INPUT
externally initiate an analog sweep or to advance to the next point of
a step list or a frequency list.
TRIGGER OUTPUT
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 GHz
of RF frequency (factory setting). This ratio is switchable to
either 0.25 or 1 volt. The switch is located on the Al2 SYTM
assembly, see Adjustments in the
Generator/HP 8360 L-Series Swept CW Generator Service Guide
information. This output is designed to drive into 2 kR or greater.

points when the swept signal generator is sweeping. This output
also supplies a -5 V pulse when the RF output is coincident with a
marker frequency.
