The digital storage oscilloscope (DSO) samples the measurement voltage and displays it as a curve with respect to time. Up to four different signals can be picked up, displayed, compared, and evaluated simultaneously. The simultaneous display of synchronous measurement signals allows for a fast and accurate survey of recurring and transient interfering impulses in the setting of crosstalk within a bus. Moreover, results may be displayed and stored prior to triggering.
The DSO is used mostly for experimental set-ups for research and development of challenges of computer and telecommunication industry. In this regard, it is an essential tool and provides a variety of measurement data that is of interest to the researcher. Low and high frequency signals on printed circuit boards and connectors can be measured and verified even at low levels.
A variety of settings and aspects is to be considered for qualified measurements. These include attenuation and amplification at the input, time basis, and a useful triggering. Tiny probes are required for a characterization of packed elements and conductive paths. These probes as well as connecting cables must match the settings and requirements of the DSO.
A calibration is mandatory prior to any measurement. A compensation of the probe can be done using the reference signal available from the front terminal. It is mandatory to wear a wristband for electrically grounding the user to prevent possible damage due to electrostatic discharge. Equivalent measures may be used.
Periodic signals are triggered and traced statically on the display of the DSO. Different triggering functions allow for an acquisition of periodic as well as transient signals. Triggering a slope is a basic function that is used very often. The X/Y-setting allows for displaying of characteristic curves and transfer functions of elements under test. All data may be stored digitally for a subsequent processing.
