The 700924 high voltage differential probe is an active voltage probe with high speed capabilities for measuring floating and high-speed differential signals in combination with single-ended input oscilloscopes. This differential voltage probe's attenuation ratio is switchable between 100:1 and 1000:1.

With increases in the speed of measured signals in recent years, it has become necessary to make floating measurements over a wide frequency band. The 700924 differential probe lets you make wide-band (100 MHz) differential input measurements by just connecting the probe to the input of a single-end input digital oscilloscope.
Oscilloscope input amplifiers are normally single-ended. They do not provide accurate measurements when used in combination with a 10:1 passive probe for measuring the gate-to-source voltage of a switching power supply, or potential difference with a common mode voltage in elements such as Insulated Gate Bipolar Transistors (IGBTs).
Furthermore, there is a risk that current will enter through the oscilloscope ground line and damage the oscilloscope.
