Using the 86100C
Optional Features and Licenses
In Oscilloscope, Eye/Mask, and TDR/TDT instrument modes, you can write
MATLAB Measurement scripts that perform scalar measurements. Measure-
ment results are listed on the results table. You can edit and assign up to four
scripts to the available toolbar buttons.

Option 202, Enhanced Impedance and S-Parameter
The Enhanced Impedance and S-Parameter software, option 86100C-202,
adds the ability to measure S-parameters in TDR/TDT Mode. S-parameters
(scattering parameters) are power ratio measurements that describe how a
test device modifies a signal. Typical S-parameter measurements include
return loss, insertion loss (attenuation), near-end cross talk (NEXT), and far-
end cross talk (FEXT). This software provides the following capabilities:
• Fast-Fourier Transform of the TDR time-domain data into the frequency do-
main. The resulting S-parameter data is displayed on a Cartesian logarithmic
magnitude graph.
• Export S-parameter data (including phase information) to Touchstone format
files. Touchstone files can be imported into Agilent's Physical Layer Test Sys-
tems (PLTS) for further analysis.
• Correct the impedance profile (peeling) of TDR traces.
