Lecroy AP030

SI 9000 and SI 9000A are active differential probes. The differential techniques employed permit measurements to be taken at two points in a circuit without reference to ground.

This allows the oscilloscope to be safely grounded without the use of opto isolators or isolating transformers.

The two signals are processed in the probe and the resultant output is fed to a single channel of the oscilloscope.

The output from the probe is a coaxial cable equipped with a standard BNC connector.

The probes are compatible with all 1 M input oscilloscopes.
