Applications

TCP0020, TCP2020 and TCP202A

The TCP0020, TCP2020, and TCP202A are a family of high-performance, easy-to-use AC/DC current probes designed for use with a variety of oscilloscopes. The TCP0020 is designed for direct connection to oscilloscopes with the TekVPI™ probe interface and the TCP202A is designed for direct connection to oscilloscopes with the TekProbe™ probe interface. The TCP2020 is designed for use with any instrument with BNC inputs and >100 kΩ input termination.

These AC/DC current probes provide sufficient performance to support 50 MHz measurement system bandwidth. The TCP0020 and TCP2020 provide a maximum 20 A_RMS measurement range, while the TCP202A provides a maximum 15 A_{DC + Peak AC} measurement range. These probes also provide excellent accuracy to current levels as low as 10 mA, important for meeting today’s challenging current measurement needs.
