Digital storage oscilloscope

Fig. 7.3 Experimental setup for the nanosecond laser Flash Photolysis with a white light continuum. A Brilland-Quantel Nd YAG laser delivers the fundamental pulses (355 and 532 nm). A pulsed XBO lamp is used as white light source. The laser signal is split in order to trigger the digital storage oscilloscope (DSO) utilizing a second photodiode (PD). Two separate detection units in different geometries—photomultiplier (PMT) in front face and a PD in side face—detect the signal in the UV/vis and NIR region, respectively. The monochromator is operated by a standard PC...

The electrode configuration was stressed with a voltage impulse of nearly a sine-half-wave shape. This waveform was used to avoid thermal influence on the pollution layer that would occur on a permanently stressed sample. The leakage current was measured by a digital storage oscilloscope. 

Special equipment for transient and impedance measurements consists of a digital storage oscilloscope and a frequency response analyzo. A suitable oscilloscop>e should have at least two channels with 1 kB (1024 measurement points) storage capacity. A frequency response analyzer is usually a complete unit which can produce the excitation signal, make naeasurements, process and analyze the measurement data.
