Datasheet
TCP0020, TCP2020, 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 kΩinput termination.
These AC/DC current probes provide sufficient performance to support
50 MHz measurement system bandwidth. The TCP0020 and TCP2020
provide a maximum 20 ARMS measurement range, while the TCP202A
provides a maximum 15 ADC + 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.
