IsoVu™
Isolated Current Probes
Measure fast-changing current in both
low- and high-current systems
A New Level of Visibility in Current measurements.
A Breakthrough in Oscilloscope Current Measurements
IsoVu isolated current probes enable measurements from DC to hundreds of MHz when paired with high-performance shunts or CVRs. Choose from three models to fit your application and budget.Complete RF isolation between the probe tip and the scope eliminates ground loops and dramatically reduces common mode noise.Low attenuation, 50 Ω input impedance, and shielded tips ensure low noise contribution.
-
Three bandwidths: 250 MHz, 500 MHz, 1 GHz
-
Up to 90 dB CMRR @ 1 MHz
-
Noise contribution < 4.7 nV/√Hz (<150 µV at 1 GHz)
Gain New Insights into SiC and GaN Power Converters
For measuring fast-changing currents in wide bandgap switching devices, shunt probes can deliver more bandwidth than clamp-on probes. IsoVu isolation eliminates ground loops, enables measurements on high-voltage circuits, and provides extremely high CMRR.
This makes IsoVu isolated current probes ideal for current measurements on shunts and CVRs on high-side SiC and GaN switching FETs.
-
250 MHz, 500 MHz, or 1 GHz bandwidth
-
1800 VRMS Common mode voltage
-
Up to 90 dB CMRR @ 1 MHz
-
1000 V CAT II Safety rating
Measure Current Draw in Nanoseconds and Microamps in Low Power Designs
Accurately measuring low-level, dynamic currents can be critical for optimizing power management in IoT and mobile devices. With IsoVu isolated current probes and wideband shunts, you’ll be able to see current consumption during specific system activities, like transitions from sleep to active states, memory accesses and I/O activity. Tektronix wideband shunts work with IsoVu current probes for real-world current measurements as low as 30 μA with unmatched bandwidth, isolation, and protection.
-
Probe bandwidth up to 1 GHz
-
Noise contribution < 4.7 nV/√Hz (<150 µV at 1 GHz)
-
Easily measure 12, 24 or 48 V rails, or higher
-
250 MHz bandwidth shunts: 5 mΩ ,50 mΩ, 500 mΩ, or 5 Ω
Minimize Connection Hassles
Flexible probe tips and cables minimize connection hassles while limiting noise. They bend easily to reduce strain for making reliable connections to your DUT. Tektronix wideband shunts use standard square pins for high performance with low cost per test point.
-
Probe tips terminate in shielded, high-bandwidth MMCX connectors; compatible with off-the-shelf SMA or BNC adapters
-
Easily connect to 25 mil square pins for on-board shunts and test points
-
Scopes automatically recognize tip attenuations and shunt values
-
Included bipod and tripod adapters provide stability
Seamless Integration with 4, 5 and 6 Series MSO Oscilloscopes
4, 5 and 6 Series MSO oscilloscopes are known for their advanced power analysis capabilities. IsoVu current probes are designed to work seamlessly with these instruments. The TekVPITM probe interface powers the probe, and automatically detects the probe and tip, allowing you to adjust probe parameters from the scope user interface. This also enables test automation using the oscilloscopes’ programming commands.
Perform Validation Testing Across Extreme Temperature Ranges
These optional extreme temperature tips enable IsoVu Isolated Current Probes to perform measurements across a wide temperature range from -40°C to +125°C.
Featuring six foot reach (1.8 m), these tips provide convenient MMCX connectivity between a DUT inside a temperature chamber and the current probe located outside the chamber. These tips are available in 1X, 10X, and 100X attenuation options and offer bandwidth performance up to 700 MHz.
