Product Details

Tektronix Oscilloscope Probes

The Tektronix current oscilloscope probe offers current measurement capabilities of 50DC continuous. The amplifier, when used with Tektronix provides a wide range of current measurement capability and spans the gap between low-level milliamp measurements to very high current levels. The oscilloscope onscreen readout of magnitude and amps reduces measurement errors with no more hand calculations.
Requires TCPA300 amplifier available separately

Features and Benefits

Bandwidth is DC to 50MHz
Lowest measurable current is 5mA
Insertion impedance is 0.35ohm at 50MHz
Rise time is 7ns
Typically less than 1% DC gain error
Bare insulated maximum wire voltage is 150V CAT II and 300V CAT II
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 ohm
Low DC drift and noise allows improved low level current measurements
