Connector BNC (f)
External auxiliary input (AUX INPUT)
Input voltage limits –10V to +10V
External AM input (EXT AM) ±1 volt into a 5 k
Ω resistor,
1 kHz maximum, resulting in
8 dB/volt amplitude modulation.
BNC (f) connector.
External trigger(EXT TRIGGER) Triggers on a negative TTL
transition or contact closure
to ground. BNC (f) connector.
Test sequence output (TEST SEQ)
By default, this connector outputs a TTL end-of-sweep
signal. It can also be programmed by the user in a test
sequence to output a user-defined TTL signal. BNC (f)
connector.
Limit test output (LIMIT TEST)
This connector outputs a TTL signal of the limit test results.
Pass: TTL high. Fail: TTL low. BNC (f)
connector.
Test-port bias input (BIAS CONNECT)
Maximum voltage +30 VDC
Maximum current
(no degradation in RF specs ) ±200 mA
Maximum current ±1 A
Connector BNC (f)
VGA video output (EXT MON)
This connector drives external VGA monitors.
HP-IB
This connector allows communications with compatible
devices including external controllers, printers, plotters,
disk drives, and power meters.
Parallel port
This 25-pin female connector is used with parallel (or
Centronics interface) peripherals such as printers and
plotters. It can also be used as a general purpose I/O port,
with control provided by test sequencing functions.
RS-232C
This 9-pin male connector is used with serial peripherals
such as printers and plotters.
DIN keyboard
This connector is used for adding an IBM PC-AT
compatible keyboard for titles and remote front-panel
operation.
Test set interconnect
This connector is used to connect an HP 8753E
Option 011 to the HP 85046A/B or 85047A test set.
On other HP 8753E analyzers, you can use signal
levels on this connector for sequencing or general
purpose I/O applications.
