General Recommendations - Teledyne T3SP Series Operator's Manual

5.1.1 General Recommendations

•
It is highly recommended to activate (D)TTC in order to achieve the
highest possible accuracy (see chapter 4).
•
A suitable probe and 50 Ω coaxial cables (SMA or RPC-3.5) must be
used for performing high-performance impedance measurements.
•
Single-ended measurements can be carried out either on channel 1
(positive step) or channel 2 (negative step). The polarity of the step
is only relevant for a step response trace, but not for impedance or
S-parameter measurements.
•
In case of differential measurements, a set of phase-matched coaxial
cables must be used. It is recommended to use the cables delivered
with the unit, otherwise the full performance cannot be guaranteed.
•
Prepare your Samples in the Sample List according to point
quick start chapter.
•
The results of the impedance measurements are displayed in the Re-
sult Visualization Window (see Fig. 5). The impedance is displayed vs.
traveling time, complying with the time axis in the Oscilloscope Win-
dow. The tolerance mask can be defined in the Impedance Measure-
ment Properties Window (for more details read section 5.1.3).
•
In (D)TDR mode some important values (averaged & min./max. im-
pedance in the impedance mask region) are shown in the right upper
corner of the Result Visualization Window as well as in the yellow re-
sult display of the Main Window (see Fig. 1).
•
The green check-mark in the upper-right corner (PASS indicator) of the
Main Window indicates whether the measurement passed the toler-
ance check. Otherwise the cross (FAIL indicator) indicates that the
