Safety Instructions
Symbols
These symbols alert you to important safety considerations.
WARNING, HIGH VOLTAGE. Risk of electric shock or burn.
CAUTION of damage to probe or instrument, or WARNING of hazard to
health. Attend to the accompanying information to protect against
personal injury or damage. Do not proceed until conditions are fully
understood and met.
General Precautions
To avoid personal injury or damage to your equipment:
Use only as specied. Using the probes and/or the equipment it is connected to in a
manner other than specied may impair the protection mechanisms.
Keep the probe body and output cable away from the circuits being measured.
Only tips are intended for contact with electrical sources.
Do not use the probe for measurements on Mains circuits. The probes do not
have a CAT rating for use on these types of circuits.
Use only indoors. Do not use in wet or explosive atmospheres.
Keep product surfaces clean and dry.
Do not operate with suspected failures. Before each use, inspect the probes and
accessories for damage such as tears in insulation or other defects in the body, cable
jacket, etc. If any part is damaged, cease operation immediately and sequester the
probes from inadvertent use.
WARNING
Do not use the probes to make measurements on circuits with voltages higher than
70 V DC or 46.7 V peak AC.
Probes are insulated with solder mask, conformal coating and rubber coating. Avoid
probing devices with sharp metal edges that might damage the probe insulation and
result in lethal electric shock.

Product Description
The T3NFP3 probe set comprises of a set of three magnetic eld probes (H) and an
electric eld probe (E) for radiated emissions pre-compliance tests of printed circuit
boards and other devices including components, connectors, wiring, power supplies,
etc.
The T3NFP3 probe set is used to measure the magnetic elds and electric elds in
the area of the device to determine the source and level of disturbance emissions.
The probes act similar as wide bandwidth antennas, picking up radiated emissions
from components, PCB traces, housing openings or gaps and from any other parts
that could be emitting RF.
Scanning the probe over the surface of a PCB assembly or housing quickly identies
locations which emit electromagnetic radiation. By changing to a probe with smaller
size, the origination of the emissions can be further narrowed down. Rotating the
probe over the device will enable the orientation of the magnetic elds to be
determined.
Additional applications are RF immunity tests by feeding a RF signal into the probe
and radiating it into potentially susceptible circuit sections. Furthermore the probes
can be used in the eld of repair or debugging to track down issues in RF signal
chains by contactless measurement of RF signal levels. One more application is non-
invasive measurement of RF building blocks such as modulators or oscillators.
Frequency, phase noise and spectral components can be measured in conjunction
with a low noise preamplier.
The passive near eld probes are connected to the 50 Ohm input of a spectrum
Analyzer such as the Teledyne Test Tools T3SA3200 or T3SA3100, or to the input of
a VNA such as the Teledyne Test Tools T3VNA1500 or T3VNA3200, or to the input of
a high sensitivity oscilloscope such as the Teledyne LeCroy high denition 12 bit
HDO and WavePro HD families, or to a regular oscilloscope such as the Teledyne
Test Tools T3DSO range. The probes can also be used with other brands of spectrum
Analyzer or oscilloscope.
The probes can then make comparative measurements of magnetic elds and
disturbance currents in the frequency range from 300 kHz to 3 GHz, though they can
be used well beyond 6 GHz.

Application
The probes are used to detect magnetic eld intensity and detect disturbance
emissions sources.
Spectrum Analyzer
or Oscilloscope
DUT
T3NFP3
Near Field Probe
There are two methods of connecting the probes to the spectrum Analyzer or
oscilloscope, either directly or via a wideband preamplier (not supplied) as shown
above. If a wideband preamplier is used then ensure that the model chosen covers
the 300 kHz to 3 GHz bandwidth.
If the probes are used without a wideband preamplier, then set the spectrum
Analyzer input attenuation to 0dB and turn on the internal preamplier if available on
your spectrum analyzer. Furthermore you can increase the dynamic range and
sensitivity by reducing frequency span, resolution bandwidth and video bandwidth.
If the probes are used with an oscilloscope then adjust the oscilloscope’s input
sensitivity to give a suitable waveform amplitude on the oscilloscope display.
Note that if the spectrum Analyzer or oscilloscope does not cover the entire 3 GHz
bandwidth then the results will be limited by the bandwidth limit of the spectrum
Analyzer or oscilloscope.

If the probes are to be used with an oscilloscope
then a SMA to BNC adaptor may be required (not

use BNC input connectors.

Compliance and Certications
EC Declaration of Conformity – Low Voltage
The probes meet the intent of EC Directive 2014/35/EU for Product Safety.
Compliance was demonstrated to the following specications as listed in the Ocial
Journal of the European Communities:
IEC/EN 61010-031:2015 Safety requirements for electrical equipment for
measurement, control and laboratory use – Part 031: Safety requirements for
handheld probe assemblies for electrical measurement and test.
Restriction of Hazardous Substances (RoHS)
The product and its accessories conform to the (EU) 2015/863 RoHS3 Directive.
