1395D – Thermal Voltage Converter – Ballantine Laboratories

Test and Measurement

Introducing the new 1395D series of Thermal Voltage Converter, with Dual Thermal Element technology. The 1395D offers double the output voltage (typically 14 mV instead of 7 mV). This higher output voltage means better resolution and increased accuracy. It can be used to measure AC Voltages between 20 Hz and 100 MHz and it can serve as a primary AC voltage standard and/or standard for calibration of AC calibrators and voltmeters.

Input Impedance:

50 ohms ± 0.3% to 12MHz
75 ohms ± 0.3% to 10MHz
93 ohms ± 0.5% to 10MHz

Thermoelement:

Couple Output: 14mV ± 12 %
Couple Resistance: less than 20 ohms.
Maximum DC Reversal Error: ±0.04% standard; ±0.005% optional.
Couple Output Voltage to Heater (ground): ± 50V (dc+ ac pk-pk) max.

Connectors:

Signal Input
