• Full control from oscilloscope through ProBus interface
• DC to 100 MHz bandwidth
• Outstanding 100,000: 1 Common Mode Rejection Ratio (CMRR)
• Gain of X1 or X10
• Industry-leading overdrive recovery
• Low noise
• Selectable BW limiting
• Two gain control modes when connected to a LeCroy oscilloscope
• Built-in Precision Voltage Generator (PVG)
• Comparator and true differential offset modes
