09 | Keysight | PrecisionProbe for Bandwidths up to 33 GHz - Data Sheet
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

Need PrecisionProbe for Bandwidths >33 GHz?
The N2807A PrecisionProbe Advanced kit allows for full
characterization and insertion loss removal of cables,
probes, and other circuit elements to 63 GHz of bandwidth
High bandwidth is enabled by Keysight’s N2806A cali-
bration pulse generator, included in the PrecisionProbe
Advanced kit, capable of producing rise-times of less
than 7 ps.
Using this external hardware the “Cal Out” edge of the
oscilloscope can be accelerated to speeds necessary
to characterize and remove insertion loss at > 60 GHz
measurement bandwidth using the same PrecisionProbe
software.
