6. Measurement Modes

In this chapter the specific measurement modes of the S/DTDR-65 and DTDR-

800 devices are described. All measurement modes are optional and must

be ordered separately

1

. The availability of measurement modules can be

checked by pressing the toolbar button

MODE

in the

Main Window

. A dia-

log showing all available measurement modes is raised.

Please note for devices with firmware version older than 5.0.0:

For each measure-

ment mode a corresponding sce-file must exist in the Config subfolder of the instal-

lation path. The sce-based measurement mode authentication becomes obsolete

in the future.

6.1 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 mea-

suring single-ended and differential (DTDR-65/800 only) controlled impe-

dance traces. The user can define tolerance masks and the characteristics

of the line by means of the

Impedance Measurement Properties Window

(section

6.1.3

).

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.

6.1.1 General Recommendations

•

It is highly recommended to activate (D)TTC in order to achieve the

highest possible accuracy (see chapter

5

).

1

The measurement mode

Ω

plus

(Impedance Measurements) is an exception. This mode

is basically integrated in the standard TDR/DTDR mode. However the user has no access
to the impedance data if this mode was explicitly excluded in the purchase order.
