frequency to +10 V at the sp ecied maximum frequency, with a
proportional voltage for frequencies between the sp ecied 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 imp edance is 3 k.
STOP SWEEP IN/OUT
stops a sweep when this input is pulled
low. Retrace do es not o ccur, 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 op eration.
10 MHz REF INPUT
accepts a 10 MHz
6
100 Hz, 0 to +10 dBm
reference signal for op eration referenced to an external time base.
Nominal input imp edance is 50 .
10 MHz REF OUTPUT
provides a 0 dBm, 10 MHz signal derived
from the internal frequency standard of the swept signal generator.
This input is a 50  connector that can b e used as the master clo ck
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 pointof
a step list or a frequency list.
TRIGGER OUTPUT
Pro duces a 1

s wide TTL-level pulse at 1601
points evenly spaced across an analog sweep, or at each p ointin a
step list or a frequency list.
VOLTS/GHz
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 lo cated on the A12 SYTM assem
bly, see
Adjustments in the
Agilent Technologies 8360 B-Series Swept Signal
Generator/8360 L-Series Swept CW Generator Service Guide
for
information. This output is designed to driveinto 2 k or greater.
Z-AXIS BLANK/MKRS
supplies a positiv e rectangular pulse
(approximately +5 V into 2 k) during the retrace and switch
points when the swept signal generator is sweeping. This output
also supplies a
0
5 V pulse when the RF output is coinciden
t with a
marker frequency.
Multi-pin Connectors
AUXILIARY INTERFACE
connector provides control signals to
the HP/Agilent 8516A S-parameter test set switch doubler. This
connector is a 25-pin D-subminiature receptacle lo cated on the rear
panel. It is also used for dual swept signal generator measurement
systems (two-tone systems), refer to
