High Bandwidth Current Probe for Aerospace and Marine Power Testing
Measure fast current transients, DC bus current and high-reliability power electronics waveforms in aerospace, aviation and marine electric power systems.
Aerospace and marine power systems require reliable current measurement across complex operating conditions. Test engineers often need both waveform fidelity and durability in harsh environments.
Challenges in Aerospace & Marine Power Testing
Aerospace and marine power systems require reliable current measurement across complex operating conditions. Test engineers often need both waveform fidelity and durability in harsh environments.
Fast Switching Currents
High-frequency switching current in aviation power electronics.
High-Current DC Buses
High-current DC bus and propulsion system measurement in marine electric platforms.
Harsh Environments
Need for stable measurement under vibration, temperature variation and long test cycles.
Limited Space
Limited space around power modules, harnesses and cabinet conductors.
Repeatability
Strict requirements for repeatable waveform data during validation and troubleshooting.
Mission-Critical Reliability

How ACP Probes Help
ACP AC/DC current probes provide non-invasive measurement for high-reliability power systems. With ranges from ±300A to ±3000A and bandwidth up to DC–50MHz, they help engineers select the right balance between bandwidth and current range.
Fast Switching Capture
Capturing high-speed switching current in power modules.
Propulsion & Bus Measurement
Measuring propulsion, DC bus and converter current.
Wide Temperature Range
Supporting wide temperature operation from −40°C to +85°C.
Simplified Wiring
Reducing wiring complexity with oscilloscope direct supply or USB Type-C supply.
Custom Configurations
Supporting customized configurations for special test platforms.
Durable Design
Stable sensor structure for demanding test environments.

Frequently Asked Questions
Which ACP model is best for aerospace power electronics?
ACP300 is recommended when high bandwidth is the main requirement. ACP1000 or ACP3000 should be considered when testing higher-current converters, buses or propulsion-related systems.
Can ACP probes be used for marine electric propulsion testing?
Yes. ACP1000 and ACP3000 are suitable for higher-current marine power and propulsion test scenarios, depending on the required current range.
What makes ACP probes suitable for harsh test environments?
ACP probes support a wide operating temperature range from −40°C to +85°C and use a stable sensor structure designed for demanding use.
Can a probe be customized for a special aerospace test platform?
Yes. Custom current range, bandwidth, jaw size, cable length and protection requirements can be discussed for special test platforms.
How do I choose between bandwidth and current range?
Start with the maximum current and highest waveform frequency you need to measure. ACP300 prioritizes bandwidth, ACP1000 balances current and bandwidth, and ACP3000 prioritizes high-current range.
