In time domain measurement modes (e.g. TDR, DTDR) the zoom can
be locked to the Oscilloscope Window zoom by pressing the toolbar
button with the lock symbol.
•
The impedance tolerance mask can be set via the Extra
items. For further information see section
Measurement Properties Window.
•
Optional: For an increased accuracy the TTC should be applied. If
TTC measurements have been performed, the corrected impedance-
/TDR-traces can be displayed by checking the Correction checkbox
in the Result Visualization Window. For a detailed description about
working with TTC, please refer to chapter
•
Please note: other rise-times than the predefined 65 ps can be sim-
ulated. This option is capable of characterizing systems with lower
and higher bandwidths. For simulating higher bandwidths (lower rise
time) an appropriate number of averages is recommended.

5.1.2 Reference Measurement

A Reference Measurement can be taken in addition to the TTC/12TC. The
software will move the zero point of the spatial axis (x = 0cm) to the position
of the open-end (the coaxial cable or the TDR-probe tip).
The measurement is performed by clicking the
of the Main Window, by pressing F6 or by using the menu item Extras
Reference Measurement. The presence of the measurement is indicated by
a yellow LED below the TTC/12TC indicators.
