S-parameter information
The S-parameter files for the probe are unique to each serial numbered probe and accessory tip. The files are stored on the
oscilloscope in a file structure that corresponds to the probe, tip, and serial numbers. The root path for the folders containing
the S-parameter is C:\ProgramData\Tektronix\TekScope\Instrumment (where Instrument is the
instrument model, such as DPO73304). Starting in this folder, look through the folders for the probe, tip model numbers, and
serial numbers. At the lowest level, there are .s3p files unique to the probe and tip.
The S-parameter files for the probe are unique to each serial numbered probe and accessory tip. The files are stored on the
oscilloscope in a file structure that corresponds to the probe, tip, and serial numbers. The root path for the folders containing
the S-parameter for Linux OS is:
/calibration/probecal/ac/<probe_nomenclature>/<probe_serial>/
and for Windows OS:
D:\calibration\probcal\ac\<probe_nomenclature>\<probe_serial>\
Where probe_nomenclature is the probe model, such as TDP7708. Starting in this folder, look through the folders for the
probe, tip model numbers, and serial numbers. At the lowest level, there are .s3p files unique to the probe and tip.
The S-parameter file names
correspond to the various
settings of the TriMode feature
and the gain setting of the probe.
For example, if the file name is
x_1X_A_0_25X.3Sp, the TriMode
setting is: single-ended A mode,
Gain setting = 0.25 (4x
attenuation).
Choose a .s3p file that matches
the TriMode setting that you are
using, single-ended (A or B),
differential (D), or common mode
(C). Note that for browser tips,
only D mode is supported.
CAUTION: Changing or deleting the S-parameter files can cause the probes to not operate properly. To avoid
problems, do not change or delete the S-parameter files.
