Tektronix Raises the Standard for Isolated Measurements

Tektronix is extending its line of isolated measurement systems. In 2016, Tektronix introduced IsoVu, a high performance, isolated measurement system with 120 dB (1 Million-to-1) common mode rejection. Tektronix is adding products to its IsoVu portfolio with a large differential voltage range and a higher input impedance.

Featuring six new models, the IsoVu family portfolio now includes products with both large differential and common mode voltage ranges. Users can now accurately measure a wide range of differential signals (5 mV to > 1,000 V) from DC to 800 MHz in the presence of large common mode voltages up to 60 kV.

The new IsoVu products also include high input impedance. The differential input resistance is up to 40 MΩ and the differential input capacitance can be as low as 2 pF. A large input impedance allows users to make measurements anywhere in their circuit without concerns about loading the signal under test. The combination of large differential voltage and high input impedance allows designers to completely characterize their systems and eliminates the need for conventional probes tied back to ground through the scope.

IsoVu models with these capabilities are available with 200 MHz, 500 MHz, 800 MHz bandwidths with either 3-meter or 10-meter fiber optic cable lengths. The 10-meter cable option offers the same performance specifications as the 3-meter option and allow users to move their test system away from the interference and radiated emissions of the device under test. The previous 1 GHz model continues to be available.
