Description
Tektronix AM503B Product Description
The Tektronix AM503B is a high-performance current probe amplifier and a core component of the AM503S current measurement system. It supports use with the A6302 (100 MHz bandwidth) or A6303 (50 MHz bandwidth) current probes, integrating voltage outputs from AC transducers and DC Hall-effect devices to enable DC-to-100 MHz bandwidth current measurements. This makes it ideal for high-precision testing in power supply systems, avionics, medical electronics, and other applications. The device is compatible with oscilloscopes featuring 10 mV/div sensitivity and 50 Ω or 1 MΩ input impedance, outputting signals via BNC connectors. It comes standard with a GPIB interface for automated programming control.
Key Features
-
High Bandwidth and Flexible Configuration: Achieves 100 MHz full bandwidth with the A6302 probe or 50 MHz bandwidth with the A6303 probe, meeting diverse testing requirements.
-
Automated Calibration and Operation: Supports rapid self-calibration without special probe adjustments; enables forced demagnetization and DC balancing via bus commands to streamline testing.
-
High Precision and Low Noise: The attenuator provides 12 calibration steps in a 1-2-5 sequence with illuminated knob skirts for clear division indication, ensuring measurement accuracy; low-noise design enhances signal fidelity.
-
Intuitive Display and Control: Features a bright LCD for real-time current and scale display; reliable front-panel controls support GPIB interface programming (IEEE-488.1 standard) for automated test systems.
-
Safety and Stability: Includes overvoltage protection (OVP) to prevent accidental device damage; power supply design ensures stable operation in complex testing environments.
-
Modular Design: As the core of the AM503S system, it can be combined with TM500/5000 power supply chassis and A63×× series probes to create multi-channel current measurement solutions.
