Application
The probes are used to detect magnetic field intensity and detect disturbance
emissions sources.
DUT
T3SA3000-NFP
Near Field Probe
There are two methods of connecting the probes to the spectrum analyser 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 30 MHz to 3 GHz bandwidth.
If the probes are used without a wideband preamplifier, then set the spectrum
analyser 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 oscilloscopes' input
sensitivity to give a suitable waveform amplitude on the oscilloscope display.
Note that if the spectrum analyser or oscilloscope does not cover the entire 3 GHz
bandwidth then the results will be limited by the bandwidth limit of the spectrum
analyser or oscilloscope.
