Conclusion
Using PrecisionProbe provides the highest level of accuracy without requiring
additional equipment. PrecisionProbe will help with accuracy in the following
ways:
– Characterize the impedance of your probe
– Remove probe to probe variation
– Remove insertion loss caused by cables
– Correct custom probes
– Correct for browser variability caused by span and length variation
– Correct for solutions such as switch matrices
The N2807A PrecisionProbe Advanced Kit provides the same award winning
software and features as the original PrecisionProbe (N2809A). While the original
PrecisionProbe was limited to a maximum of 33 GHz characterization bandwidth,
PrecisionProbe Advanced extends this functionality out to 63 GHz by including
Keysight’s N2806A Calibration Pulse Generator.
