The software quickly (less than five minutes in most cases) and accurately

characterizes the desired element in the system without adding more equipment.

PrecisionProbe

– Characterizes probe input impedance

– Properly Creates Custom Probe Transfer Function = VOut / VIn or VOut/VInc =

VOut/VSrc

– Removes unwanted cable loss

Now every probe and cable in the system can have the exact same response

probe to probe or cable to cable, without the inaccuraies that using one model

can produce. Custom probes can now be properly characterized and unwanted

responses can be removed.

Not only does PrecisionProbe characterize the cables, it allows for immediate

use on the same instrument. When combining PrecisionProbe with the 90000

Q-Series, 90000 X-Series, and 90000A Series oscilloscopes, one can characterize

their measuring system and be using it within five minutes without adding more

complicated, expensive equipment. PrecisionProbe saves time and money while

increasing accuracy.

When combining InfiniiMax probes with switches between the amplifier and the

probe head, PrecisionProbe allows for full correction and automation of each

probe’s path. Full automation is then available to allow for quick swapping of the

inputs.
