CONNECTORS
The open circuit voltage is TTL high and is internally pulled low
when the swept CW 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 flO0 Hz, 0 to +lO dBm
reference signal for operation referenced to an external time base.
Nominal input impedance is 50 R.
10 MHz REF OUTPUT provides a 0 dBm, 10 MHz signal derived
from the internal frequency standard of the swept CW generator.
This input is a 50R 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 ps 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.
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 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 kR or greater.
Z-AXIS BLANK/MKRS suppl’ies a positive rectangular pulse
(approximately +5 V into 2 kR) during the retrace and switch points
when the swept CW 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 CW generator measurement systems (two-tone
systems). Refer to Step Control Mastes for more information.
