CONNECTORS
frequency to
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
STOP SWEEP IN/OUT
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 swept signal generator stops its sweep.
Externally forcing this input high will not cause damage or disrupt
normal operation.
10 MHz REF INPUT
accepts a 10 MHz
Hz, 0 to
reference signal for operation referenced to an external time base.
Nominal input impedance is 50
10 MHz REF OUTPUT
provides a 0
10 MHz signal derived
from the internal frequency standard of the swept signal generator.
This input is a 50 connector that can be used as the master clock
reference output for a network of instruments.
TRIGGER INPUT
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.
TRIGGER OUTPUT
Produces a 1
wide TTL-level pulse at 1601
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 Al2 SYTM
assembly, see Adjustments in the
HP 8360 B-Series Swept Signal
Generator/HP 8360 L-Series Swept CW Generator Service Guide
for
information. This output is designed to drive into 2
or greater.
Z-AXIS
supplies a positive rectangular pulse
(approximately
V into 2
during the retrace and switch
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.
Multi-pin Connectors
AUXILIARY INTERFACE
connector provides control signals to the
HP 8516A S-parameter test set switch doubler. This connector is a
25-pin D-subminiature receptacle located on the rear panel. It is also
used for dual swept signal generator measurement systems (two-tone
systems), refer to
Step
Control
for more information.
