Product Details

Tektronix TCP Series

The Tektronix TCP300 Series of split-core current probes incorporates transformer and Hall effect technology. The TCP300 models TCP303 (796-2683 ), TCP305A ( 781-0810 ) and TCP312A ( 781-0801 ) are used with amplifier TCPA300 ( 764-4391 ), available separately, to provide high performance capability from low level milliamp measurements to the measurement of very high current levels. The TCP0030A ( 781-0807 ) is powered directly by oscilloscopes with the TekVPI interface.

Easy-to-use and accurate AC/DC current measurements
Connects to some Tektronix oscilloscopes using the TekVPI™ probe interface
Provides automatic units scaling and readout on the oscilloscope display
Split-core construction allows easy circuit connection
Typically less than 1% DC gain error
Low Noise and DC Drift
Easy to Degauss and Autozero
Setup controls and probe status/diagnostic indicators on probe hardware and via oscilloscope UI display menu

Tektronix Oscilloscope Probes

The Tektronix current oscilloscope probe offers current measurement capabilities of 30ADC continuous. The amplifier, when used with provides a wide range of current measurement capability and spans the gap between low-level milliamp measurements to very high current levels. This oscilloscope onscreen readout of magnitude and amps reduces measurement errors with no more hand calculations.
Requires TCPA300 amplifier available separately
