Tektronix Inc., a leading provider of measurement solutions is extending its leadership in isolated measurement systems. After introducing IsoVu system in 2016 with revolutionary 120 dB common mode rejection, the company is raising the standard again by adding new products to the IsoVu portfolio. These products feature a higher input impedance as well as larger differential voltage range. 

 

The IsoVu portfolio now features 6 new models 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.

 

 

Moving on, the differential input resistance is up to 40 MΩ and the differential input capacitance can be as low as 2pF. Owing to this large input impedance, users can make measurements anywhere in their circuit without concerns about loading the signal under test. 

Moreover, 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 the ground through the scope. 

 

“The high bandwidth and high isolation voltage capability of the Tektronix IsoVu Probe is a tremendous tool, aiding in accurate verification of various EPC eGaN FET based high side gate driver power supply designs,” said Michael de Rooij, Vice President of Applications Engineering.  “The Tektronix team understood the needs and challenges for a new way to measure high performance differential voltages when it designed IsoVu,” added David Reusch, Executive Director of Applications. 

 

“The ability to measure with the extraordinary performance of this probe is so impressive that EPC has decided to include IsoVu compatible connections on all new development boards such as the EPC9063 and many more. And now with IsoVu’s large differential voltage range and high input impedance, this will open up even more measurement capability. “

 

 

The updated IsoVu models will be available for order after its shipping in the late Q3 of 2017.
