TPR1000

Overview

The TPR1000 is an active power rail probe designed for low-noise measurement of power supply ripple and noise. It provides a bandwidth from DC to 1 GHz, enabling precise analysis of high-frequency switching components in modern power electronics. The device features a DC coupling mode with a frequency range of 10 kHz to 1 GHz and supports a maximum AC RMS value of 1 V. It offers a bias range of ±60 V and maintains a DC linearity of less than 0.1%. The probe operates within a temperature range of -40 °C to +85 °C with standard accessories.

Feature Summary

• Provides ultra-low noise performance for accurate power integrity testing
• Features wide bandwidth extending up to 1 GHz for high-speed signal analysis
• Includes integrated bias capability for measuring signals superimposed on DC rails

Applications

• Characterization of DC-DC converter output ripple and noise
• Analysis of power delivery network (PDN) impedance and stability
• Debugging electromagnetic interference (EMI) sources in switching power supplies

Procurement Notes

Verify compatibility with the specific oscilloscope model before purchase, as software integration is required for full functionality. Confirm that the operating environment remains within the specified temperature limits when using standard accessories. Ensure the input voltage does not exceed the maximum DC bias rating to prevent damage to the probe front-end circuitry.

Selection Notes

Select the TPR1000 when measurements require a bandwidth up to 1 GHz with minimal added noise floor. This probe is suitable for applications involving fast transient events or high-frequency switching regulators where passive probes introduce excessive capacitance. Consider the TPR4000 if frequencies exceeding 1 GHz are necessary, noting potential software compatibility constraints with certain older oscilloscope series.

Part Context

The TPR1000 belongs to the TPR series of active power rail probes manufactured by Teledyne LeCroy. These probes are engineered specifically for characterizing power supplies and digital circuits. They complement the company's oscilloscope portfolio by providing specialized measurement capabilities that standard passive probes cannot achieve due to bandwidth and loading limitations.

Replacement Considerations

The TPR4000 serves as a higher-bandwidth alternative within the same product family. Users requiring greater frequency response should evaluate the TPR4000, while those needing lower cost or simpler setups might consider passive differential probes, though these will lack the active amplification and low loading characteristics.
