Conclusion

Using PrecisionProbe provides the highest level of accuracy

without requiring additional equipment. PrecisionProbe will help

with accuracy by doing the following:

– Removing insertion loss caused by cables

– Characterizing the impedance of your probe

– Removing probe to probe variation

– Correcting for loss and non-linearities in custom probes

– Correcting for solutions such as switch matrices
