The TCP300 and TCP400 Series AC/DC Measurement Systems are extremely advanced current measurement systems designed to meet today's current measurement needs. These slide-in probes utilize transformer and Hall effect technologies to offer wide bandwidth measurements from DC to 100MHz, with measurable currents as low as 1 mA and as high as several thousand amps (with the CT4 converter). When connected to a Tektronix TDS oscilloscope with a TEKPROBE Level II or Tek Connect (with TCA-BNC) interface, current measurements and calculations can be performed simply and easily. By adding plugins such as TDSPWR2 power measurement software, users can gain additional measurement capabilities. With these measurement capabilities, current measurements have become easier than ever before.
The TCPA300/TCPA400 current measurement family provides broadband AC/DC measurement from DC up to 100 MHz using transformer and Hall‑effect technology. The system covers a wide current range—from 1 mA to several thousand amperes—when paired with the appropriate probe, and integrates directly with Tektronix TDS oscilloscopes via the TEKPROBE interface.
The document lists technical specifications, safety certifications (UL, CSA, EN), power requirements, mechanical and environmental characteristics, and complete ordering information including optional accessories and service options. It also explains how the probes and amplifiers can be combined for various current ranges and how to order parts using the provided part numbers.
| Bandwidth (‑3 dB) | DC‑100 MHz (TCPA300/TCPA400) |
|---|---|
| Typical DC Accuracy | ±1 % of reading |
| Input Impedance at 1 MHz | 0.08 Ω (TCPA300) |
| Minimum Measurable Current | 1 mA |
It offers a –3 dB bandwidth of DC to 100 MHz.
The TCPA300 amplifier works with the TCP312, TCP305, or TCP303 probes.
It is listed on the UL3111‑1 and UL3111‑2‑032 certifications, as well as Canadian CSA and EU EN61010 standards.
Order the TCP312 probe (DC‑100 MHz, 30 A) which requires the TCPA300 amplifier.
