Tektronix Current Probe Amplifier, TCP300 and TCP400 Series and Probes
Brand: TektronixA range of Tektronix AC/DC Current Amplifiers and Associated Accessories from the TCP300 and TCP400 Series. 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.
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 30A, 50A, and 150A DC continuous. For even higher current levels, the TCPA400 amplifier with the TCP404XL current probe measures 500A DC continuous and 750A DC continuous, derated with duty cycle.
Higher-frequency performance is available with the TCP312A w/TCPA300 providing ≥100MHz bandwidth and a maximum current of 30A DC.
The TCP300/TCP400 current measurement systems seamlessly integrate with your TDS series oscilloscope.
- Automatic scaling and units - 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
- Available probes TCP312A, TCP305A, and TCP303
- Available Current Probe Amplifiers: TCPA300 and TCPA400
