1157A Active Probe, 2.5 GHz

• 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 1156A, 1157A, and 1158A family of active probes offers R & D engineers the performance they need to probe small geometries in hard-to-reach areas on the DUT. These probes were designed specifically for the Infiniium Series, and InfiniiVision 5000, 6000 and 7000 Series oscilloscopes (except for 6000 Series 100MHz models).

As the speeds in your design increase, you may notice more overshoot, ringing, and other anomalies when connecting an oscilloscope probe. Probes form a resonant circuit where they connect to the device. If this resonance is within the bandwidth of the oscilloscope probe you are using, it will be difficult to determine if the measurement anomalies are due to your circuit or the probe.

The Keysight 1156/7/8A probes optimize performance to make your job easier.

Notice: The Keysight 1157A/58A was discontinued June 1, 2014. End of support life for these products is Sept. 1, 2019. The N2750A-52A InfiniiMode differential probes or N2795A/96A single-ended active probes are the recommended replacement probes. For use with Infiniium 548xx, 8000, 80000 models, order InfiniiMax 1131A with InfiniiMax probe head.
