TICP Series IsoVuTM Isolated Current Probes make accurate, low-noise, dynamic current measurements using shunt and current viewing resistors, even in the presence of fast-changing common mode voltages that occur on floating devices in power circuits.  Available with three bandwidths - 1 GHz, 500 MHz, and 250 MHz - the TICP Series is compatible with Tektronix 4, 5 and 6 Series MSO oscilloscopes, including the latest B models.

Complete galvanic isolation eliminates ground loops and enables very high common mode rejection with common mode voltage rating of 1000 V CAT II; Pollution degree 2 (see datasheet for additional information).  In a 1X configuration, the probe measures ±0.5 V range and its 50 O input offers extremely low noise of less than 150 µVRMS at 1 GHz – ideal for measuring low voltage drops on current shunts. Different attenuation tips are available to extend the differential voltage range. Depending upon the shunt used, these probes can perform current measurements from microamperes (uA) for low-power mobile design, to hundreds of amperes for industrial and mobility systems.
