Size reduced to 1/5 compared to existing products
1 GHz isolated probe
Achieves industry-leading common mode rejection ratio


Tektronix announced on the 3rd the launch of the TIVP series, the second-generation IsoVu isolated probe.
Since its initial market introduction in 2016, this product has undergone significant improvements in form factor and functionality. The new second-generation IsoVu probe, like its first-generation counterpart, utilizes patented electro-optical technology to capture signals and power the probe, eliminating the need for electrical connection to the oscilloscope. Unlike conventional high-voltage differential probes, the IsoVu probe delivers high bandwidth, dynamic range, and industry-leading common mode rejection ratio (CMRR) across the probe's entire bandwidth.

The CMRR rating of non-isolated probes degrades rapidly as frequency increases, making high-frequency measurements impossible. Additionally, by using optical cables, long cable runs are supported and the probe is largely unaffected by EMI.

The TIVP series probe is 80% smaller than the first-generation, and this compact size advantage allows easier access to measurement points that were previously unreachable. Additionally, the controller box that was previously required as a separate bundle has been eliminated and integrated into the probe itself.

The new probe delivers higher visibility and voltage sensitivity when measuring ±50V in wide bandgap designs thanks to increased sensitivity and reduced noise.

Accuracy has also been improved in various aspects including DC accuracy, gain accuracy across the entire input range, and temperature drift compensation. This enables more in-depth characterization of wide bandgap designs with greater energy efficiency.

In addition, the expanded dynamic range of the sensor head requires fewer tips to handle the same voltage range as the first-generation IsoVu. This reduces the time required to perform device testing, eliminating the possibility of errors during tip swapping, and eliminates the need to purchase multiple tips as with the first-generation IsoVu, thereby reducing costs.

Srinivasan Nuthikatla, Director of Mainstream Solutions Division, stated, "This second-generation IsoVu will enable a wider range of customers to leverage cutting-edge isolated measurement technology for R&D, verification, and EMI troubleshooting work."
