PAMS-C is a user-friendly, transmitter and receiver
system that measures shielding effectiveness of RF shielded
enclosures. Lightweight and compact, each unit measures
approximately 12″ x 5″ x 5″ and weighs 5.5 lbs., making
PAMS-C ideally suited to field measurement tasks. Rugged
construction ensures instrument survivability in a field
test environment.
PAMS-C incorporates a self-calibrating architecture that
provides for ease of use. It requires only minimal operator
instruction for error-free operation. Its backlit LCD output
displays shielding effectiveness, battery status, and other
operating parameters.
PAMS-C allows the user to set a minimum shield level
threshold. While sniffing around the enclosure, a tone
will sound in the headphones should the shield level drop
below the threshold. The pitch of the tone varies based
on the measured shield level’s distance from the set
threshold value.
A USB interface is included on both the transmitter and
receiver. This allows for serial control of selected func
tions and parameters. The PAMS-C receiver also includes a
Spectrum Monitor mode, which displays ambient RF signals
present within the test environment.
The PAMS-C receiver and transmitter are synthesized, with a
minimum tuning step size of 100 kHz. Both units are battery
powered, and can be operated in an AC mode when connected to
the external battery charger. Normal battery operation time is 5
hours for the receiver, and 2 hours for the transmitter. A complete
charge cycle is
completed in approximately 2 hours.
The receiver provides accurate level detection for signals in the
range of –120 dBm to 0 dBm. Typical accuracy is +/-1.0 dB. An
internal limiter provides protection to the receiver in the unlikely
event that the receiver and transmitter are connected together.
The receiver has a DC bias voltage on the connector, which may be
used to power an external device such as a switch.
The transmitter provides a maximum output power of
+30 dBm (1 watt). Output power can be adjusted in 1, 2, or 5 dB
steps down to –30 dBm. Internal ALC circuitry maintains output
level accuracy. The output of the
transmitter is fully protected against damage.
The PAMS-C System includes transmitter, receiver,
batteries, 2 portable antennas, chargers, manual and
a rugged transit case.
