2.4 Probe Test jig
The probe test jig is used with a spectrum analyzer or measuring receiver and tracking
generator to verify that the magnetic probes have not been damaged in use. Connect
the probe test jig, label side up, to the output of the tracking generator and the probe to
the input of the spectrum analyzer or measuring receiver and insert the probe fully into
the probe test jig. Of the two ways to insert the probe the one with the maximum output
should be used.
With the tracking generator output set to -10 dBm and the spectrum analyzer or
measuring receiver set as appropriate, a plot similar to Fig. 6 should be displayed.
Typically, the plot should be within 3 dB of those shown, large changes, e.g. 10 dB or
more, indicate a damaged probe.
