RF isolated Current Probe for Oscilloscopes
29 November 2024 - Tektronix announced the new TICP Series IsoVu isolated current probes. TICP IsoVu probes are the industry’s first current shunt probes to use RF isolation, providing complete galvanic isolation between measurement systems and devices under test, delivering high-bandwidth, low-noise current measurements in high-voltage applications compared to existing probes on the market or alternative shunt measurement techniques. Available in bandwidths up to 1 GHz, these probes enable engineers to capture accurate measurements of fast-changing currents on their oscilloscopes across a wide voltage range in nanoseconds – from microamps to kiloamps.
“The wide measurement range covers previously inaccessible high-voltage environments, from fast-switching SiC and GaN power converters to low-power applications like battery performance testing in mobile devices – all with a single probe,” said Daryl Ellis, Tektronix’s General Manager of Entry and Mainstream Portfolio. “As the global demand for power innovation accelerates, we're setting new benchmarks in precision, safety, and scalability, empowering customers to push the limits of what is possible in industries ranging from automotive to renewable energy.”
Key features:
- Complete galvanic RF isolation, eliminates ground loops
- More than 30X higher common-mode rejection (CMRR) than traditional differential voltage probes: 140 dB CMRR at DC, up to 90 dB at 1 MHz
- Ultra-low noise contribution – in a 1X configuration, the 50 Ω input offers extremely low noise of <4.7 nV / √Hz (<150 μV at 1 GHz)
- Available in 3 models with bandwidths of 1 GHz (TICP100), 500 MHz (TICP050), and 250 MHz (TICP025)
- Uses TekVPI probe interface to integrate with Tektronix 4, 5, and 6 series MSO oscilloscopes
