The DP9030-Z is an important accessory for any laboratory involved in power electronics.  It allows isolated and floating measurements with any oscilloscope whilst the oscilloscope can remain grounded. Using a DP9030-Z 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 DP9030-Z is powered from a 9V battery.
