A fully equipped electromagnetic
compatibility (EMC) laboratory
requires a wide variety of
instruments, equipment, and
accessories to allow measurements to be made accurately
and efficiently. On a smaller
scale, design engineers and test
technicians also need an
assortment of measurement
tools to evaluate their product
designs prior to formal EMC
compliance testing.
This EMC accessories catalog
helps you quickly find the
equipment you need to make
your EMC measurements.
You’ll find a large selection of
antennas, current probes, LISNs,
cables, tripods, preamplifiers,
and other accessories. Each is
designed to enhance your EMC
measurement capabilities and
provide lasting value.
Hewlett-Packard is continually
expanding its line of EMC
accessories to ensure the most
comprehensive line of EMC test
equipment available. Be sure to
check with your local HP sales
representative if you need an
item that is not listed in this
product overview.

HP 11966A Active Magnetic
Loop Antenna
The HP 11966A active loop
antenna was designed specifically
for three-meter VDE 0871 Limit
B magnetic-emissions testing.
A built-in preamplifier in the
antenna base matches the low
impedance of the loop with the
50 watt input of the EMI receiver
and provides a consistent, linear
antenna factor over the frequency
range of the antenna. A built-in
saturation indicator alerts the
operator to overload conditions.
The standard unit is supplied
with a 120 VAC/60 Hz battery
charger. Option 220 replaces the
standard battery charger with a
220 VAC/50 Hz unit.
HP 11966B Active Monopole
Antenna
This broadband active rod E-field
antenna has a preamplifier
built into its base. This design
provides sensitivity, high
dynamic range, and a flat
antenna factor, yet eliminates
the need for manual tuning or
bandswitching. A built-in
saturation indicator alerts the
operator to overload conditions.
The standard unit is supplied
with a 120 VAC/60 Hz battery
charger. Option 220 replaces the
standard battery charger with a
220 VAC/50 Hz unit.
