Description

The model PA-010 and PA-103 are general purpose,
broadband, high gain, bench top preamplifiers. These
preamplifiers reduce floor noise and increase system
sensitivity to low level signals during Electromagnetic
Interference (EMC) testing. They also provide input
isolation to your expensive test equipment. The PA­103 has a frequency range of 1 MHz to 1000 MHz. The
PA-010 operates from 100 Hz to 30 MHz.

The simple front panel consists of two 50 W matched
BNC connectors for input and output. The preampli­fiers were designed to have minimal gain variation for
the entire frequency range to reduce EMC measure­ment errors.

Each preamplifier is individually calibrated and the
gain data is shipped with the unit. Power to the model
PA-103 is supplied by a 9 VAC, 1 AMP external wall
mount adapter supplied with the preamplifier. The
PA-010 is powered by 115 VAC, 60 Hz line input.

Application

The PA-103 and PA-010 are primarily used for EMC
radiated emissions testing. These preamplifiers can be
used during EMC testing for FCC, CISPR, EN, FAA
and MIL-STD. These preamplifiers could also be used
in other applications that require a high gain preampli­fier.

The enhanced system sensitivity due to high gain is
very helpful when making EMC measurements using
antennas on an Open Area Test Site (OATS) or prob­ing a printed circuit board using Near Field Probes.
This allows measurements of those frequencies from
the equipment under test, that are not visible on the
spectrum analyzer display unless amplified. The
preamplifier gain will cause peaks to be visible above
the background noise of the analyzer. These frequen­cies may go undetected if a preamplifier with a high
gain was not used.

In addition, preamplifiers could improve sensitivity
of counters and power meters. The PA-103 and PA­010 can also be used to increase the available power
from your sweeper or signal generator.
