The N2804A 300-MHz differential probe provides the superior differential signal measurements required for today’s high-speed power measurements such as measuring characteristics of switching power devices, DC-DC converters, class D amplifiers or automotive buses. The probe offers 100:1 attenuation ratio, allowing it to be used adequate for up to +/-300V DC+peakAC of high voltage differential measurements with high CMRR. The differential probe has a differential input resistance of 4 M? and 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 flat frequency response even with the extension leads and the probe tip accessories used. The probe is powered by Keysight’s oscilloscope AutoProbe interface.
