DC to 50 MHz, 50A DC, 50A PK AC/DC input coupling Low insertion impedance reduces device under test loading Split-core construction allows easy circuit connection Requires TCPA300 Amplifier All TCP300/400 probes include: compliance and safety instructions, certificate of traceable calibration. The TCP300 and TCP400 Series AC/DC current measurement family is a highly advanced current measurement system for today's current measurement needs. When connected to Tektronix oscilloscopes with TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC) interfaces, current measurements and calculations are simple and easy
