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. F b e s 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 h e 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 H P 11722A covers the Erequency range 100 kHz
to
2 . 6 GHz; the H P 11792A covers the
range 50 MHz to 26.5 GHz and is intended for use with the H P 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.
