China Tektronix Active Power Rail Probes TPR1000 and TPR4000 Suppliers, Product
Tektronix TPR1000 and TPR4000 are high-performance active power rail probes designed to solve critical measurement challenges in modern electronic systems—specifically targeting the accurate detection of AC ripple, noise, and voltage fluctuations on DC power rails.
TPR1000 and TPR4000 are high-performance active power rail probes designed to solve critical measurement challenges in modern electronic systems—specifically targeting the accurate detection of AC ripple, noise, and voltage fluctuations on DC power rails. Tailored for power integrity engineers, hardware designers, and test professionals in automotive, industrial, consumer electronics, and high-speed digital industries, these probes address the limitations of traditional oscilloscope probes (e.g., insufficient offset range, high noise, poor bandwidth) when measuring low-voltage, high-frequency power rails.
Core Positioning: Solving Modern Power Rail Measurement Pain Points
As electronic devices become more compact, high-speed, and low-power (e.g., 5G chips, EV controllers, mobile processors), DC power rails operate at lower voltages (often <5V) with tighter tolerances. Traditional probes struggle to:
Isolate small AC ripple (200 μVp-p to 800 mVp-p) from large DC offsets (up to ±60 VDC);
Capture high-frequency noise (up to 4 GHz) without introducing probe-related interference;
Minimize loading effects on sensitive power rails.
The TPR1000/TPR4000 resolve these issues with a low-noise, high-offset, wide-bandwidth design, enabling precise characterization of power rail integrity—critical for preventing system instability, data errors, or component failure.
Compatibility with Oscilloscopes
The TPR1000/TPR4000 integrate seamlessly with a wide range of oscilloscopes to maximize usability:
Compatible models: 6 Series MSO, 5 Series MSO, 4 Series MSO, 3 Series MDO, MDO3000, MDO4000C, MSO/DPO5000B, DPO7000C, DPO70000C/DX/SX;
Special Notes
MDO3000/MDO4000C: Software incompatibilities reduce measurement accuracy at vertical scales <2 mV/division (full accuracy maintained at ≥2 mV/division);
DPO70000 Series: Requires the optional TCA-VPI50 adapter for connection.
Typical Applications
These probes excel in scenarios where power rail integrity directly impacts system performance or safety:
Automotive & EV: Probing power rails for ADAS chips, EV battery management systems (BMS), and infotainment controllers to detect ripple that could disrupt sensor signals or communication.
Industrial Electronics: Testing power supplies for PLCs, motor drives, and industrial sensors—ensuring noise does not affect precision control.
Consumer & Mobile Devices: Characterizing power rails for smartphones, laptops, or IoT devices, where low noise is critical for battery life and signal integrity (e.g., memory, Ethernet connectivity).
High-Speed Digital Systems: Analyzing noise coupling between power rails and high-speed data paths (e.g., PCIe, DDR5) to prevent data corruption.
