PR-261 - Near Field "Sniffer" Probe Set
The PR-261 is the ideal tool kit for the investigation of RF electromagnetic
fields. It is indispensable for EMI pre-compliance testing during productive
development, prior to third party testing. The set includes three hand-held
probes with a built-in pre=amplifier covering the frequency range from
10 kHz to 100 MHz. The set includes one magnetic field probe, one electrical
field probe and one high impedance probe. All have high sensitivity
and are matched to the 50W inputs of spectrum analyzers. The power can
be supplied either from the batteries or through a power cord directly
connected to B+K Precision Model 2630. Signal feed is via a 1.5 meter
BNC-cable. When used in conjunction with a spectrum analyzer, the probes
can be used to locate and qualify EMI sources. They are especially suited
to locate emission "hot spots" on PCBs and cables, as well as evaluate
EMC problems at the breadboard and prototype level. They enable the
user to evaluate radiated fields and perform shield effectively comparisons.
Mechanical screening performance and immunity tests on cables and components
are easily performed. Faulty components and poor bonding locations can
be isolated. The magnetic probe incorporates a high degree of rejection
of both stray and direct electrical fired, and provides far greater
repeatability than with conventional field probes. Measurements can
be made on the very near field area that is close to components or radiation
sources. The electric field (monopole) probe has the highest sensitivity
of all three probes. It can be used to check screening and perform pre-compliance
testing on a comparative basis. The high impedance probe is used to
measure directly on the components under test or at the conductive trace
of a PC board. It has an input capacitance of only 2 pF and supplies
virtually no electrical charge to the device under test.

TE-26 - 50-ohm Feedthru Termination
 The
output levels of the tracking generator of the Models 2620 and 2630
are correct only when terminated into 50 ohms. The Model TE-26 provides
a 50 ohm termination and a BNC feedthru connection so that the tracking
generator output may be fed into a high impedance circuit at a calibrated
level.

ZTF-1 - 50-ohm to 75-ohm Matching Network
Most RF networks (except cable TV) have an impedance of 50 ohms.
The spectrum analyzers also have a 50 ohm input impedance, which allows
direct connection. Cable TV networks have an impedance of 75 ohms. To
use the spectrum analyzer with 75 ohm networks, Model ZTF-1 will match
the 75 ohm network to the 50 ohm input impedance of the spectrum analyzer.
