Tektronix Oscilloscope Current Probe TCP404XL, 2 MHz Bandwidth, BNC Connector

The Tektronix TCP404XL Oscilloscope Current Probe delivers advanced current measurement capabilities for a wide range of electronic and electrical testing scenarios. Designed for engineers and technicians requiring precision and reliability in laboratory and industrial environments, this probe combines transformer and Hall Effect technology within a split-core construction.

With a bandwidth of 2 MHz, the TCP404XL enables accurate detection of rapidly fluctuating currents, making it suitable for high-speed applications in power electronics, communications, and semiconductor testing. Its 175 ns rise time ensures fast response and minimizes distortion in signal capture. The probe's low insertion impedance minimizes circuit loading, preserving the integrity of the device under test.

Connection to oscilloscopes is facilitated by a BNC interface, providing secure and robust compatibility with TEKPROBE Level II, TekConnect (with TCA-BNC), or TekVPI (with TPA-BNC) equipped scopes. Automatic scaling and units, along with on-screen magnitude display, reduce manual calculation errors and streamline measurement workflows.

Status indicators are integrated to communicate operational status and signal potential error conditions, such as probe open, overload not terminated into 50 Ohm, and non-compatible probe types. Degaussing is supported for enhanced probe performance and reduced noise. The probe maintains low DC drift, enabling improved low-level current measurements, critical for sensitive applications.

Safety is assured with certifications for CAT I, CAT II, and CAT III up to 600V, complying with standards such as CAN/CSA C22.2, IEC61010, UL3111, and EC Council Directives. The TCP404XL is suitable for development, analysis, and troubleshooting of power supplies (switching and linear), semiconductor devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs), power inverters/converters, electronic ballasts, motor drives, industrial and consumer electronics, and mobile communication systems.

This versatile current probe is an essential tool in laboratory, manufacturing, telecom, and industrial test environments, providing reliable performance and safe operation when measuring AC and DC currents in circuits requiring precision and rapid response.
