TA1000

• Accuracy: Class 0 .01

• Operating frequency: DC ~ 10 kHz

• Maximum output current: 120 A

• Short-Term stability: 0.001%

• LCD touch screen

• Can be used as wideband current standard source with the built-in signal generator

TA1000 is a high-precision and high-stability wideband current source. It can output wideband current with the built-in signal generator directly. It can also be used as a wideband transconductance amplifer to accept AC/DC Voltage/current signals from any calibrator, signal generator or power supply.
