200 MHz, 3.5 pF, 1 MOhm Active Differential probe
ZD200 - Teledyne LeCroy
With the ProBus interface, the ZD200 becomes an integral part of the oscilloscope. The probe sensitivity and offset are automatically optimized based on the oscilloscope gain settings, so control is transparent to the user. When used with a LeCroy digital oscilloscope, no external power supply is required.
