High-voltage Differential Active Probes (Continued)
N2804A/N2805A high-voltage, high-speed differential probes
The N2804A and N2805A differential probes provide the 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.
The N2804A 300-MHz differential probe offers 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 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 while using the extension leads and probe tip accessories.
The 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.
