The LeCroy ZD1000 is an active differential probe engineered for signal integrity measurements in high-speed digital systems. It delivers 1 GHz warranted bandwidth with typical performance extending to 1.2 GHz, capturing fast transients with 375 ps rise time (10%-90%, typical). The probe’s 1.0 pF differential input capacitance and 1 MOhm differential input resistance minimize circuit loading, preserving signal fidelity during measurement. An 18 Vp-p differential range with ±8 V offset capability accommodates diverse signal environments. Common mode range extends from -10 V to 20 V nominal, while 60 dB CMRR at 50/60 Hz rejects power-line interference. System noise of 1.75 mVrms typical supports detailed low-level signal analysis. The probe integrates directly with Teledyne LeCroy oscilloscopes via ProBus, drawing power from the instrument without external supplies or batteries. Transparent control of gain and offset occurs at the oscilloscope—no probe-side adjustments needed.
