Differential active probes are like two probes in one. Instead of measuring a test point in relation to a ground point (like single-ended active probes) differential probes measure the difference in voltage of a test point in relation to another test point. Featuring high bandwidth, excellent common-mode rejection ratio (CMRR) and low noise, the LeCroy ZD Series differential probes are ideal for applications such as automotive development and failure analysis, together with wireless and data communication design. With its ProBus interface, the ZD Series probe becomes an integral part of the oscilloscope.

Probe gain and offset controls are transparent to the user, making it easier to probe the circuit without concern for which gain setting to choose. When used with a LeCroy digital oscilloscope, no external power supply is required. Teledyne LeCroy also offers PK111 ( 7898337 ) which is a replacement accessory kit for ZD500, ZD1000 & ZD1500.

CMRR (typical) 80dB @ 60 Hz (ZD200), 60dB @ 50/60 Hz (ZD500, ZD1000, ZD1500)
