TA1000 Transconductance Current Standard Source
The TA1000 is a high-precision and high-stability wideband current source, designed for advanced calibration, power measurement, and high-accuracy testing applications. With its built-in signal generator, the device can directly output wideband current without requiring external equipment.
Additionally, the TA1000 operates as a high-performance wideband transconductance amplifier, allowing input of AC or DC voltage/current signals from external equipment such as calibrators, signal generators, or power supplies. This versatility makes the TA1000 suitable for laboratories, metrology centers, and industrial calibration facilities requiring precise and stable current output.
