Teledyne LeCroy WaveLink Differential Probe Series (8-13 GHz) - Manual (Page 21)

Operator's Manual
replacement, Teledyne LeCroy recommends that you return the probe platform/cable assembly and
amplifier module to the factory for a complete calibration and test to ensure guaranteed
performance. This is because there may be small differences in performance of interconnect leads
supplied at different times.
If a positioner tip is purchased at time of original shipment of the other probe components, this is
also calibrated and serialized with the other components. If it is purchased at a later date and you
have provided Teledyne LeCroy with the original probe serial number the tip is used with, Teledyne
LeCroy calibrates the positioner tip to your existing components and supplies a file on a
USB memory stick for installation on your oscilloscope. Follow the instructions provided with the file
and memory stick in order to load this file and ensure proper calibrated performance with your
existing probe components.
Finally, if the spring-loaded tips and tip sockets need to be replaced on your positioner tip, see
"Replacing Spring-Loaded Tips and Tip Sockets on the Positioner Tip" on page 34 for more
information.
De-Embedding Probes
Teledyne LeCroy probes are calibrated at the factory using a Vector Network Analyzer (VNA) to
measure a system (probe plus test fixture) frequency response. The test fixture is de-embedded
from the measurement using Teledyne LeCroy's Eye Doctor tools so the remaining frequency
response is due to the combination of the test signal and the probe loading on the test circuit. The
system frequency response is then calculated for these remaining circuit elements.
If you wish to de-embed the effect of probe loading on your circuit, you can use the appropriate
equivalent circuit model in "Probe Input Impedance and Loading" (on page 1) and Teledyne LeCroy's
Eye Doctor tools to accomplish this.
You can also use Teledyne LeCroy’s Virtual Probe option. This option allows you to select the probe
tip from a list of supported tips. Your selection applies a corresponding s-parameter file that is
derived from the equivalent circuit model of the tip.
Handling the Probe
The WaveLink series probe is a precision test instrument. Exercise care when handling and storing
the probe. Always handle the probe by the platform/cable assembly. Avoid putting excessive strain
on any cable or interconnect lead or exposing the probe cables to sharp bends.
ESD Sensitive: The tips of the probe are sensitive to ElectrostaticDischarge (ESD). Avoid
causing damage to the probe by always following anti-static procedures (wear wrist strap,
etc.) when using or handling the probe.
