    摘要: A method for setting voltage resolution in particle beam measuring devices wherein band width of a measured signal processing is modified. In order to set a desired voltage resolution simply, reliably, and with high precision, a signal noise of the measured signal is measured. This signal noise is compared to a desired value for the measured signal resolution, and the band width of the measured signal processing is modified such that the signal noise of the measured signal is less than or equal to the desired value for the measured signal resolution.

    摘要: An electron beam testing device system for stroboscopic potential measurements of a test subject utilizes a scanning electron microscope having a beam suppression or blanking system. The blanking system deflects the electron beam across an aperture during each edge of a blanking pulse connected to control the blanking system so that two electron pulses are generated for each blanking pulse. A detector produces a signal responsive to a secondary electron beam resulting from impact of each of the electron pulses on the test subject. A signal processing unit with an associated gate circuit all preferably incorporated in a boxcar integrator processes only one of the two electron pulses associated with each blanking pulse. A phase control preferably within the boxcar integrator is connected to control the gate circuit and a blanking pulse generator for producing the blanking pulse.
