FEATURES
Input Connector Type
R = Receptacle Connector
P = Plug Connector
Complete thermal converter module using the MJTC thermal
converter as a core device.
Dedicated high-frequency chassis with input and output
connectors.
High Frequency Thermal Voltage Converter
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.
TVC1 = Mounted SMA Connector
TVC2 = No SMA Connector
INTERNAL SCHEMATIC
APPLICATIONS
For high-precision AC-DC transfer standards.
