Keysight 1157A Active Probe, 2.5 GHz – Probe Only

The Agilent 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 54800 Series oscilloscopes. As the speeds in your design increase, you may notice more overshoot, ringing, and other perturbations 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 perturbations are due to your circuit or the probe. Agilent is the only company that has overcome the resonance formed by the connection of a probe to a device. The Agilent 1156/7/8A probes optimize performance to make your job easier.
