TCP0030A is a high-performance, easy-to-use AC/DC current probe designed for use and direct connection to oscilloscopes with the TekVPI? probe interface. This AC/DC current measurement probe provides greater than 120 MHz of bandwidth with selectable 5 A and 30 A measurement ranges. It also provides exceptional low-current measurement capability and accuracy to current levels as low as 1 mA, important for meeting today's challenging current measurement needs.

KEY FEATURES

• Easy-to-use and accurate AC/DC current measurements
• Intelligent communication with TekVPI? oscilloscopes provides:
  • Units scaling and readout. Automatic, on-screen readout of amps and magnitude. Manual setup is not required. Hand calculation from volts to amps is unnecessary
  • Push button degauss and Autozero functionality
  • Probe status and diagnostic indicator LEDs
  • Remote GPIB/USB probe control
• Split-core construction allows easy circuit connection
• High accuracy with typically less than 1% DC gain error
• Low noise and DC drift
• 3rd party safety certification
