Tektronix TCPA300

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.

Key performance specifications

AC/DC measurement capabilities

• DC - 100 MHz, Current Probe Amplifier (TCPA300) uses:
  • DC - 100 MHz, 30 A DC (TCP312A)
  • DC - 50 MHz, 50 A DC (TCP305A)
  • DC - 15 MHz, 150 A DC (TCP303)

1Derated with duty cycle

Key features

• Automatic scaling and units 1 - Oscilloscope on-screen readout of magnitude and amps reduces measurement errors with no more hand calculations
• AC/DC input coupling
• Low insertion impedance reduces device under test loading
• Split-core construction allows easy circuit connection
• Status indicators provide visual operating status and notification of potential error conditions - degauss, probe open, overload, not terminated into 50 Ω, noncompatible probe type
• Low DC drift and noise allows improved low-level current measurements
• 3rd party safety certification

1Requires a TDS TEKSCOPE oscilloscope or a TekConnect oscilloscope with TCA-BNC adapter

Applications

• Development and analysis solutions for designers, installers, and service personnel in telecom, data comm, computer, and semiconductor power electronics environments for:

  • Power supplies (switching and linear)
  • Semiconductor devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs)
  • Power inverters/converters
  • Electronic ballasts
  • Industrial/consumer electronics
  • Mobile communications (phone, satellite, relay stations)
  • Motor drives
  • Transportation systems (electronic vehicles, electric trains, locomotives, avionics)

Meets today's AC/DC current measurement applications

The TCPA300 amplifier, when used with TCP312A, TCP305A, or 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 30 A, 50 A, and 150 A DC continuous. For even higher current levels, the TCPA400 amplifier with the TCP404XL current probe measures 500 A DC continuous and 750 A DC continuous, derated with duty cycle.

Higher-frequency performance is available with the TCP312A w/TCPA300 providing ≥100 MHz bandwidth and a maximum current of 30 A DC.

Measurement errors and manual calculations are now a thing of the past

With this new series of current measurement tools, automatic control and on-screen scaling and units is provided for users of Tektronix TDS3000, TDS500, TDS600, TDS700, TDS5000, TDS6000, and TDS7000B series oscilloscope systems (the DPO3000, MDO/MSO/DPO4000, MSO/DPO5000, and DPO7000 series oscilloscopes, the TPA-BNC adapter is required).

The TCP300/TCP400 current measurement systems seamlessly integrate with your TDS series oscilloscope.

Even non-TEKPROBE systems can use the TCPA300/400 series to make proper current measurements by simply multiplying the measured output voltage on the oscilloscope by the TCPA300/400 series range setting.
