Teledyne T3NFP3, User Manual, Page: 5 / 13

Application
The probes are used to detect magnetic field 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 preamplifier (not supplied) as shown
above. If a wideband preamplifier is used then ensure that the model chosen covers
the 300 kHz to 3 GHz bandwidth.
If the probes are used without a wideband preamplifier, then set the spectrum
Analyzer input attenuation to 0dB and turn on the internal preamplifier 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.
