Differential Voltage Probes
DP150/DP200pro
The DP differential isolation probes are an important accessory for any laboratory involved in power electronics and high voltage systems. These probes allow isolated and floating measurements with any oscilloscope or data recorder, whilst the oscilloscope can remain grounded. Using a DP150 or DP200pro probe, differential and floating measurements can be made on a variety of ac power systems like 230V/110V ac input power supplies, chopped and switching power supplies, thyristor controllers, variable speed motor drives (PWM signals), motor inrush current and measurement across current shunts. The isolated input is made via two 4mm/banana safety sockets. The BNC output allows easy connection to an oscilloscope. The DP probes can be powered from a 9V battery or external power supply.

High Voltage Differential Probes
A high voltage differential probe is used for measuring the voltage difference between two test points where neither test point is at ground. High voltage differential probes from Tektronix can be used for signals up to 6000 V. These probes are the best choice for making non-ground referenced, floating or isolated measurements in large part due to their common mode rejection capability. These products are designed, manufactured, and serviced by Tektronix.

Optically Isolated Measurement System
IsoVu
IsoVu offers complete galvanic isolation and is the industry’s first measurement solution capable of accurately resolving high bandwidth, low voltage differential signals in the presence of large common mode voltages. The stand out feature of IsoVu™ is its best in class common mode rejection across the entire bandwidth. Accurate differential measurements rely on a measurement system’s bandwidth, rise time, common mode voltage, common mode rejection capability, and the ability to connect to smaller test points to characterize devices that are shrinking in size and increasing in performance. Despite these requirements, advancements in test and measurement for power testing, EMI testing, ESD testing, and remote measurement capability have been minimal at best and have not kept pace with changing requirements. While differential voltage probes have had modest performance gains in regard to bandwidth, these probes have failed to make any substantial improvements in regard to common mode rejection, and connectivity. IsoVu is a leap forward in technology and is the only solution with the required combination of high bandwidth, high common mode voltage, and high common mode rejection to enable these differential measurements.
