Product Information

  • Accessory Type: Current Probe Amplifier
  • Features: Instruction/service manual, TEKPROBE interface cable, Male-to-Male BNC cable (50?), 50? feedthrough termination, Certificate of Traceable Calibration
  • For Use With: Tektronix TCP312A, TCP305A & TCP303 Probes
  • SVHC: To Be Advised


The TCPA300 from Tektronix is a current probe amplifier. This amplifier when used with TCP312A, TCP305A and TCP303 probes, provides a wide range of current measurement capability and spans the gap between low level milliamp measurements to very high current levels. These three probes provide current measurement capabilities of 30A, 50A and 150A DC continuous and for even higher current levels. Higher frequency performance is available with TCP312A providing greater than or equal to 100MHz bandwidth and maximum current of 30A DC. The TCPA300 is approved by UL3111-1 first edition, CAN/CSA C22.2 number 1010.1-92, EN61010-1:2001, EC Council Directive 89/336/EEC, FCC Part 15, Subpart B class A and AS/NZS 2064.1/2 standards.
