General Information Model
8901B
Option
003.
This option provides both an output for the internal local oscillator signal and an input
for an external local oscillator signal. Both connections are located on the rear panel.
(This
output
is
provided automatically with option
030
series instruments.)
Option
004.
This option allows operation at line frequencies ranging from
48
to
400
Hz. Operation
at frequencies greater than
66
Hz
is
restricted
to
less than
126.5
Vac line input.
Option
030.
The High Selectivity Measurement option provides the capability
to
measure single-
sideband carrier noise
(AM
or phase) quickly and accurately up
to
1.3
GHz with an external
LO.
(An
output for the internal local oscillator and an input for an external local oscillator signal
is
provided
with these options.) This option
is
ordered with one of the following filter options:
Option
032.
This option provides a
12.5
kHz adjacent channel filter.
Option
033.
This option provides a
25
kHz adjacent channel filter.
Option
035.
This option provides a
30
kHz (Cellular Radio) alternate channel filter.
Option
037.
This option provides
a
carrier noise filter.
Options
907-909.
These options are described in
Mechanical Equipment Available.
Option
910.
This option provides an extra copy of both the
Operation and Calibration Manual
and
the
Service Manual.
Accessories Supplied
The Accessories Supplied are pieces of equipment which are shipped automatically with every
Modulation Analyzer.
Line Power Cable.
The line power cable may be supplied in several plug configurations, depending
on the destination of the original shipment. Refer
to
Power Cables
in Section
2
of this
Operating
Information
manual.
Fuses.
Fbes with a
2.5A
rating for
115
Vac
(HP
2110-0083)
and
a
1.5A
rating for
230
Vac (HP
2110-0043)
are supplied. One fuse
is
factory installed according
to
the voltage available in the country
of original destination. Refer
to
Line Voltage
and
he Selection
in Section
2
of this
Operating
Information
manual.
Electrical Equipment Available
This equipment
is
available
to
be ordered for the Modulation Analyzer
after
the time of sale.
HP-IB Controller.
The Modulation Analyzer has an HP-IB interface and can be used with any HP-IB
compatible computing controller or computer for automatic systems applications.
Sensor Module.
The HP
11722A
and
11792A
Sensor Modules enable you
to
characterize a signal
using a single input connector. Switching back and forth between the Modulation Analyzer’s SENSOR
input and RF INPUT connectors happens automatically with these modules (which contain an internal
switch). The HP
11722A
covers the Erequency range
100
kHz
to
2.6
GHz; the HP
11792A
covers the
range
50
MHz to
26.5
GHz and
is
intended for use with the HP
11793A
Down
Converter. Special care
is taken with each sensor module
to
minimize input
SWR
and resulting errors.
A
low SWR attenuator
isolates the power sensor from the source-under-test, reducing mismatch. Microwave hardware and a
selected RF input cable further improve SWR and insertion loss.
