6.7 Permittivity Measurements (optional, not for DTDR-800)

The permittivity measurement mode is designed to work with an open-en-

ded coaxial line sensor (e.g. SDM-10G of Sequid GmbH ). This mode was

developed for material measurement applications and it is essential to acti-

vate the

TTC

(see chapter

5

).

•

Right-click an existing sample and select the permittivity mode. In

case it is not available, please
