AUX I/O: 25-pin connector that provides for
single cable interface with another 68XXXB
(master-slave operation) or with other WIL-
TRON instruments such as the WILTRON 562
Scalar Network Analyzer. A pinout diagram for
this connector is shown in Figure A-2.
SEQ SYNC OUT: Provides a +5V signal during
sweep retrace, at bandswitching points, and
during each frequency step in step sweep
mode. Also, when video markers are selected,
provides –5V marker pulses and a –10V se-
lected marker pulse during forward sweep.
BNC connector.
HORIZ OUT: Provides a 0V to 10V ramp dur-
ing all sweep modes, regardless of sweep
width. In the CW mode, provides a voltage
between 0V and 10V proportional to the full
frequency range of the instrument. When the
CW Ramp is enabled, connector provides a
repetitive 0V to 10V ramp. BNC connector,
50
Ω
impedance.
10 MHz REF IN: Accepts an external 10 MHz
±
100 Hz, 0 to 10 dBm time-base signal. Auto-
matically disconnects the internal high-stability,
time-base option, if installed. BNC connector,
50
Ω
impedance.
