Multi-pin 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.
MHz REF INPUT
10
reference signal for operation referenced to an external time base.
Nominal input impedance is 50 R.
10 MHz REF OUTPUT
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
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
information. This output is designed to drive into 2 kR or greater.
Z-AXIS BLANK/MKRS
(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.
AUXILIARY INTERFACE
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.
