The Tektronix MDO4AFG is a hardware key module that adds arbitrary function generator capability to the MDO4000C series mixed-domain oscilloscope. This one-time upgrade enables signal simulation, waveform generation up to 50 MHz, and noise injection for margin testing—all integrated directly into the oscilloscope’s interface. Users can generate standard waveforms, load custom arbitrary waveforms up to 128,000 points, and edit signals on-screen or via Tektronix ArbExpress software.
Technical Specifications
Output Characteristics:
• Maximum output frequency: 50 MHz

– Key Features
• Sensor signal simulation for design validation
• Noise injection and perturbation for margin testing
• Tight integration with MDO4000C oscilloscope UI
• Permanent, one-time hardware key activation
• Extensive built-in waveform selection
– Typical Applications
• Emulating real-world sensor outputs during design verification
• Performing stress testing with controlled signal degradation
• Custom waveform generation for specialized test scenarios
– Compatibility & Integration
The MDO4AFG module is designed exclusively for Tektronix MDO4000C series oscilloscopes. Installation activates the arbitrary function generator as a native instrument within the host oscilloscope’s measurement suite, eliminating separate software or external hardware requirements.
