Tektronix TCPA300/TCPA400 AC/DC Current Measurement System | Probe Arus
The TCP300 and TCP400 Series AC/DC current measurement family is a highly advanced current measurement system for today's current measurement needs.
Available models include TCPA300, TCPA400, TCP303, TCP305A, TCP312A, TCP404XL.
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.
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.
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).
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.
The TCP300/TCP400 current measurement systems seamlessly integrate with your TDS series oscilloscope.
Key Features
- 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 – 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
