Product overview: 52120A Transconductance Amplifier
The 52120A is designed for users whose ability to address their calibration workload may be
limited by the output current, accuracy and drive capability of their present test equipment,
including:
- Calibration professionals in a calibration/standards lab or an electrical utility
- Manufacturers of power/energy instrumentation and meters, power quality analyzers or power converters
- Users of electrical test and measurement equipment
The 52120A operates as a transconductance amplifier with:
- 5522A/5502A/5520A/5500A Multi-Product Calibrators
- 5730A*/5700A/5720A Multifunction Calibrator
- 6105A*/6100B* Electrical Power Standard
- 5080A Multi-Product Calibrator
- 9100 Universal Calibration System
- Any calibrator, signal generator or power supply capable of sourcing 2 V or 200 mA, dc or ac
*Special closed-loop operating mode
You may also operate your 52120A in closed-loop mode, seamlessly communicating with your Fluke Calibration 6105A or 6100B Electrical Power Standard to deliver enhanced 52120A accuracy.
