FEATURES

Complete thermal converter module using the MJTC thermal

converter as a core device.

Dedicated high-frequency chassis with input and output

connectors.

Employs the virtual-TEE configuration ("internal" or "built-in")

TEE

Evaluation of frequency characteristic of the ac-dc transfer

difference possible at 10-6 level up to 1MHz.

APPLICATIONS

For high-precision AC-DC transfer standards.
