The Tektronix TCP404XL is a very high-current AC/DC current probe for engineers who need the TCPA400 amplifier system for demanding measurement environments. It delivers DC to 2 MHz bandwidth, 500 A continuous current, and up to 750 A peak pulse capability for heavy-current waveform analysis. This model is the strongest fit for inverters, high-current power supplies, motor drives, and other applications where maximum current capacity matters more than bandwidth or direct-connect convenience.

Best for very high current testing up to 500 A with the TCPA400 amplifier.

Ideal Applications

• High-current power supplies and power inverters

• Semiconductor and power device validation

• Industrial electronics and motor drives

• Transportation systems and heavy-current troubleshooting

In The Box

• TCP404XL AC/DC current probe

• Probe cover

• Instruction sheet

• Certificate of traceable calibration

FAQ: Frequently Asked Questions

1) How do I know if the TCP404XL is the right TCP Series model for my application?
The TCP404XL is the best fit when you need very high-current measurement capability and are already using, or plan to use, the TCPA400 amplifier system.

2) What current and bandwidth performance does the TCP404XL provide?
The TCP404XL provides DC to 2 MHz bandwidth, 500 A continuous current capability, and up to 750 A peak pulse handling when used with the TCPA400 amplifier.

3) Does the TCP404XL connect directly to an oscilloscope?
No, the TCP404XL requires the TCPA400 amplifier as part of the Tektronix current measurement system.

4) What features support measurement usability?
Its split-core design, automatic scaling support, low insertion impedance, and visual status indicators help improve day-to-day measurement workflow.
