Teledyne LeCroy at APEC: 1000A Current Probe with Industry-Leading Bandwidth

At APEC, Bryan DeLuca from eeVids stopped by the Teledyne LeCroy booth with Jason Lemke to take a closer look at what’s new—highlighting a powerful new tool designed for engineers working with high-current systems.

Introducing the CP1000 Current Probe

One of the key announcements at the show is Teledyne LeCroy’s new CP1000 current probe. This probe is capable of measuring up to 1000 amps with a bandwidth of 1.5 MHz, positioning it among the highest-performing current probes available.

This level of performance is becoming increasingly important as industries like electric vehicles and data centers continue pushing higher power levels.

As Lemke explained, measuring power means accurately capturing both voltage and current—and as systems scale, measuring higher current becomes a critical challenge.

Why High Bandwidth Matters

It’s not just about measuring high current—it’s about doing it accurately at high speeds.

Modern systems are switching faster than ever, with higher frequencies and faster rise times. That means engineers need probes that can keep up without losing signal fidelity.

The CP1000 addresses this by combining:

• High current measurement (up to 1000A)
• Wide bandwidth (1.5 MHz)
• Compatibility with modern high-speed power systems

Seamless Integration with LeCroy Oscilloscopes

The CP1000 is designed to integrate directly with Teledyne LeCroy oscilloscopes using the company’s ProBus interface.

Once connected, the oscilloscope automatically detects the probe and enables built-in features such as:

• Auto zeroing
• Degaussing
• Automated setup and control

This tight integration simplifies setup and ensures accurate measurements right out of the box.

Multi-Channel Power Analysis

At the booth, the system was demonstrated using an eight-channel oscilloscope configured for three-phase power analysis.

This type of setup allows engineers to:

• Measure voltage and current across all three phases
• Analyze pulse-width modulated (PWM) signals
• Observe system behavior during dynamic conditions, such as motor startup

By capturing both voltage and current simultaneously, engineers can gain a complete picture of how power is being delivered and consumed in real time.

Advanced Measurement and Analysis Tools

Once the data is captured, the oscilloscope provides a wide range of automated measurement capabilities, including:

• Voltage RMS
• Current RMS
• Power calculations

Results can be displayed in organized tables for quick analysis, allowing engineers to immediately understand system performance.

For deeper analysis, users can zoom in on specific portions of a waveform to examine detailed behavior—such as current spikes during motor startup or switching transitions.

Built for Modern Power Applications

As power systems continue to evolve, engineers need tools that can keep up with increasing demands. The CP1000 current probe and Teledyne LeCroy’s oscilloscope platform are designed to provide:

• High-current measurement capability
• High-bandwidth performance
• Integrated, automated workflows
• Flexible analysis tools for custom measurements

Together, these capabilities help engineers better understand and optimize systems in applications like EV powertrains, industrial drives, and data center infrastructure.
