Which measuring instrument should be chosen? A multimeter is suitable for basic measurements of voltage, current and resistance. An oscilloscope lets you see the waveform and changes as a function of time, while a logic analyzer is particularly suitable for examining digital buses and signals. A spectrum analyzer, on the other hand, is used to analyze the frequency content of signals.
In Partcon's current selection of measuring instruments, Rigol, Owon and PeakTech are highlighted, and the multimeters also include Fluke and Kyoritsu models.
