Keysight N2804A N2805A High-Voltage Differential Probes
The Keysight N2804A and N2805A differential probes provide superior general-purpose differential signal measurements that are required for high-speed power measurements such as measuring characteristics of switching power devices, DC-DC converters or class D amplifiers, vehicle bus measurements, and high-speed digital system designs. Both probes are powered by the oscilloscope’s AutoProbe interface.
The Keysight N2804A 300-MHz differential probe offers a 100:1 attenuation ratio, allowing it to be used adequately for high voltage signal measurements. The differential probe has a differential input resistance of 4 MΩ and a low input capacitance of 4 pF to minimize circuit loading. The probe comes with a pair of extension leads (30 cm long) with a damping resistor built in to damp out the in-band resonance and provide a flat frequency response even while using the extension leads and probe tip accessories.
The Keysight N2805A is a 200-MHz differential probe designed to provide superior differential signal measurements with a long cable length (5 m), making it ideal in an environment where extended cable length is required. This probe comes with an extensive set of probe tip accessories for use with small and large components in tight spaces.
Both probes allow conventional earth-grounded Keysight oscilloscopes to be used for safe floating signal measurements. Because of the outstanding common-mode rejection ratio of the probes across the full frequency ranges, probes allow the measurement of small differential signals in the presence of much larger common-mode signals typically found in power measurements.
