TEE
Evaluation of frequency characteristic of the ac-dc transfer
difference possible at 10-6 level up to 1MHz.
Input Connector Type
R = Receptacle Connector
P = Plug Connector
High Frequency Thermal Voltage Converter
TVC1 = Mounted SMA Connector
TVC2 = No SMA Connector
INTERNAL SCHEMATIC
APPLICATIONS
For high-precision AC-DC transfer standards.
