specifications, calibration data, maintenance and repair, and storage conditions of
the N5532A Sensor Module.

Description
General Information
Description
The N5532A is intended to be used with the N5531S or the early N5530S
Measuring Receiver System. It is essentially a power sensor with a power splitter
at the input. See Figure 1-1 on page 7. In use, the sensor module's two output
cables are connected to a power meter (E4418/19, E4416/17, or N1911/12 Series)
and the Performance Spectrum Analyzer (PSA) RF Input. When using an N1911
or N1912 Series power meter, it is necessary to use an adapter (N5532A Option
019) to connect the output cable of the sensor module to the power meter. The
sensor module is calibrated such that the power meter indicates the power supplied
by the source under test.
The N5532A Sensor Module is offered in four frequency configurations:
• Option 504 covers 100 kHz to 4.2 GHz
• Option 518 covers 10 MHz to 18 GHz
• Option 526 covers 30 MHz to 26.5 GHz
• Option 550 covers 30 MHz to 50 GHz
(with adaptor 11903D 2.4mm (f) to Type N (m))
The sensor module accurately measures power levels from -20 dBm to +30 dBm
(10 μW to 1 W). Calibration Factor (Cal Factor) information is unique to each
sensor module and is supplied on a floppy disc included with each N5532A. Please
refer to “Installing the Calibration Factors” on page 2-12 for more information on
using the Cal Factor Data.

Description
General Information
NOTE The N5532A Sensor Module is compatible ONLY with the newer E4418/19,
E4416/17, or N1911/12 Series power meters. They are NOT compatible with the
earlier 430 Series or 70100 power meters. If used with an N1911/12 Series power
meter, an adapter (N5532A Option 019) is required to connect the dc cable to the
power meter.

General Information
Instruments Covered by Manual
These instruments have a two-part serial number: the prefix (two letters and the
first four numbers), and the suffix (the last four numbers). The two letters identify
the country in which the unit was manufactured. The four numbers of the prefix
are a code identifying the date of the last major design change incorporated in your
Agilent Technologies product. The four-digit suffix is a sequential number and
coupled with the prefix, provides a unique identification for each unit produced.
The contents of this manual apply directly to all serial numbers unless otherwise
indicated.

Installation
Initial Inspection
Inspect the shipping container for damage. If the shipping container or packaging
material is damaged, it should be kept until the contents of the shipment have been
checked mechanically and electrically. If there is mechanical damage notify the
nearest Agilent Technologies office as shown in Table 4-3 on page 48. Keep the
damaged shipping materials (if any) for inspection by the carrier and an Agilent
Technologies representative.
Operating Precautions
NOTE For optimal results, the sensor module must be placed on a supportive surface with
the serial number label facing up. This orientation provides repeatable
measurements by eliminating strain on the input connector.
The input connector should be torqued to 12 in-lb (135 Ncm) for the type-N
connector, 8 in-lb (90 Ncm) for the APC 3.5 mm connector, or 8 in-lb (90 Ncm)
for the 2.4 mm connector to ensure a repeatable connection in order to meet the
published specifications. Exceeding these torque settings may damage the
connector.
Connect the sensor module by turning only the hex nut portion of the connector.
Damage can occur if torque is applied to the sensor module body.
The connector plastic insulator bead deteriorates when contacted by acetone,
trichloroethylene, carbon tetrachloride, benzene, etc.
WARNING BEFORE CONNECTING THE SENSOR MODULE TO OTHER
INSTRUMENTS, ensure that all instruments are connected to the protective
(earth) ground. Any interruption of the protective earth grounding will cause
a potential shock hazard that could result in personal injury and cause
damage to the sensor module.
