Differential probes are a type of oscilloscope probe based on the differential amplification principle. They convert a signal floating between two points into a signal to the ground to observe differential signals.
1. Have the probe and a digital oscilloscope with a probe interface ready.
2. Insert the probe interface completely into the oscilloscope input, and confirm that the BNC connector and interface pin are securely fastened. You will hear the latch click when the connectors lock into place.
3. When you connect the probe to a digital oscilloscope with a probe interface, the probe’s attenuation ratio and input coupling are set automatically.
4. Attach any of the provided attachments or attachments that you constructed to the probe head signal input terminals.
