–9
/day
(after 30 days)
Yearly aging rate 0.5 ppm/year
Output 0 dBm minimum
Nominal output impedance 50 Ω 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 approximately 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) (8753ES only)
Maximum voltage +30 VDC
Maximum current ±200 mA
(no degradation in RF specs)
Maximum current ±1 A
Connector BNC (f)
VGA video output (EXT MON)
This connector drives external VGA monitors.
GPIB
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
peripherals. It can also be used as a general
purpose I/O port.
RS-232C
This 9-pin male connector is used with serial
peripherals.
DIN keyboard
This mini-DIN connector is used for adding an
IBM PC-AT compatible keyboard.
Test set interconnect
This connector is used to connect an 8753ES
Option 011 to the 85046A/B or 85047A test set.
8753ES analyzers without Option 011 can use
signal levels on this connector for sequencing
or general purpose I/O applications.
