Wide Linear Dynamic Range allows access to today's logic voltage levels. Variable DC Offset allows correction for DC levels, to bring the signal into the probe's linear dynamic range. Probe Offset is controlled by a compatible instrument or externally by the probe itself. Truer Signal Reproduction and Fidelity Ultra-low Input Capacitances and High Input Resistances allow making measurements at unknown impedance test points by maintaining higher probe input impedance across a wider bandpass and reduce ground lead loop effects allowing the use of longer ground leads than a standard passive probe. Bandwidths allow improved AC and DC signal characterization and testing.
Active probes maintain a higher input impedance throughout their frequency range.
R combination allows the acquisition of the fastest rise times and accurate amplitude measurements and provides less signal drian than a conventional passive probe. Small signal circuit analysis P6201 with its 1X sensitivity or P6249, P6245, P6243, P6204 and P6205 with 11 K high resolution mode. The use of active probes or low capacitance probes is recommended. The specific model depends upon the frequency and measurement response required. Low input C and high input R minimize circuit disturbance by reducing any additional impedance to the circuit.
