Features: 2.5 GHz bandwidth Small size makes probing easier 100 k-ohm, 0.8 pF, non-resonant input impedance +/- 15 V offset 5 V peak-to-peak dynamic range; for waveforms with edges >3nsec, dynamic range is >12Vpp Accessories designed for minimal loading on your device and optimum response AutoProbe interface compatible The Keysight 1157A active probe offers R & D engineers the performance they need to probe small geometries in hard-to-reach areas on the DUT. This probe is designed specifically for the Infiniium Series, and InfiniiVision 5000, 6000 and 7000 Series oscilloscopes (except for 6000 Series 100MHz models).
