Differential Oscilloscope Probes, High Voltage

Differential Probes allow you to view differential signals.

Differential signals are signals that are referenced to each other rather than to ground.

While a matched pair of single-ended oscilloscope probes can be used, a true differential probe typically gives higher performance, providing high CMRR, broad frequency range, and minimal time skew between inputs.

Differential signaling transmits data over two complementary wires. The signal pair is routed together to a receiver, which subtracts them from each other to recover the original signal.

Differential signaling is becoming more common as rates increase. Differential signaling eliminates common mode noise, It also reduces the need for a common reference voltage between the transmitter and the receiver against which the signal is compared to determine its logic level, eliminating some signal integrity issues such as "ground bounce".
