1. Overview

The TE3000 is designed based on TUNKIA's latest IPMA⁽¹⁾ technology. The complete system consists of a main unit, a current range expander (optional), and supporting software. The main unit is comprised of a main control board, an I/O board (optional), a standard voltage source board, a current source and small-signal voltage source board, and a small-signal measurement board (optional). The accuracy for DC voltage and DC current is of Class 0.005 / 0.01.

(Note IPMA (1): — a proprietary technology trademark of TUNKIA, is the abbreviation for Integrated Precision Measurement Architecture. IPMA is a new generation of high-precision, modular, and highly reliable measurement instrument architecture introduced by TUNKIA. It integrates precision electromagnetic measurement technology with high-speed bus technology, effectively addressing the challenges of achieving ultra-precision measurement with conventional modular instruments.)
