5. Measurement Modes

In this chapter the specific measurement modes of the T3SP-series devices

are described. The availability of measurement modes can be checked by

pressing the Main Windows toolbar button MODE. A dialog showing all avail-

able measurement modes is raised.

5.1 Impedance Measurements (Modes TDR & DTDR)

Using the impedance measurement mode is a common task in printed cir-

cuit board design and signal integrity testing. This mode allows for measur-

ing single-ended and differential controlled impedance traces. The user can

define tolerance masks and the characteristics of the line by means of the

Impedance Measurement Properties Window (section 5.1.3).

For performing impedance measurements the standard (D)TDR measure-

ment mode must be used. The difference between impedance and TDR

(step response) traces is observable in the Result Visualization Window, show-

ing (TTC corrected) impedance traces instead of TDR traces. When selecting

the impedance visualization mode, a tolerance mask can be enabled.
