Tektronix Oscilloscope Probe Amplifier TCPA300 for AC/DC Measurement System, DC to 100 MHz, Screen Display TCPA300

Tektronix TCPA300 Oscilloscope Probe Amplifier is a high-performance amplifier designed for use with the TCPA300 AC/DC Measurement System. It supports current measurements over a wide frequency spectrum, from DC up to 100 MHz, providing precise and reliable results.

This probe amplifier integrates with Tektronix oscilloscopes featuring TEKPROBE Level II, TekConnect, or TekVPI interfaces. Its oscilloscope screen readout displays magnitude and current in amps, which helps reduce manual calculation errors.

The device incorporates automatic scaling with AC/DC input coupling and features low insertion impedance to reduce loading impact on tested devices. Its split-core construction facilitates convenient circuit connections without the need for disassembly.

Status indicators visually confirm operating conditions and alert users of potential errors such as probe overload, improper termination, or open probes. Its low DC drift and noise floor enhance low-level milliampere current measurements, making it suitable for detailed development and analysis tasks.

Applications span various industrial and commercial sectors, including power supplies (both switching and linear), semiconductor devices (SCRs, IGBTs, MOSFETs), power inverters and converters, electronic ballasts, industrial consumer electronics, mobile communications, and motor drive systems for transportation like electronic vehicles and avionics.

The TCPA300 requires compatible Tektronix current probes like TCP305 or TCP312, sold separately, for complete current measurement solutions. Operates from DC to 100 MHz frequency range suitable for current probe amplification.

Features an oscilloscope screen display for magnitude and current readings to reduce calculation errors. Automatic scaling and units for accurate AC/DC input coupling measurements. Low insertion impedance minimizes loading effect on devices under test.

Split-core design enables easy connection to circuits without disassembly. Status indicators provide clear notifications for operating status and error conditions. Low DC drift and noise improve the accuracy for low-level current measurements.

Compatible with Tektronix TCP305 or TCP312 current probes (sold separately). Ideal for power electronics, telecom, semiconductor testing, and industrial applications. This product is certified to ISO 9001, CE, and ISO 14001 standards, ensuring quality and environmental compliance. It is manufactured in China for Tektronix.
