$2,450.00
The Tektronix TCP2020 is a high-performance AC/DC current probe with 50 MHz bandwidth and 10 mA sensitivity, designed for precise current measurement in high-speed and power-sensitive applications.
Tektronix TCP2020 – 50 MHz AC/DC Current Probe (20 A RMS, 100 A Peak Pulse).
The Tektronix TCP2020 is a precision AC/DC current probe designed for engineers working with dynamic current signals up to 20 A RMS or 100 A peak pulse. With DC to ≥50 MHz bandwidth and ≤7 ns rise time, this probe enables accurate measurement of fast transients and small current variations, making it essential for power supply validation, semiconductor device testing, and motor drive diagnostics.
Thanks to its 10 mA minimum sensitivity, the TCP2020 accurately captures low-level current activity, while maintaining high fidelity in demanding environments. Its split-core design allows non-intrusive clamping around conductors without disconnecting the circuit — an advantage for both lab and field measurements.
For full flexibility, the TCP2020 is compatible with oscilloscopes via BNC interface and powered by an external AC adapter. If you\’re using portable scopes, explore options in our Portable Oscilloscopes article for real-world field testing insights.
This model is widely used alongside advanced Oscilloscope Probes and Mixed Signal Oscilloscopes, particularly when high accuracy and low noise performance are essential.
