Which measuring device should you choose? A multimeter is suitable for basic measurements of voltage, current and resistance. With an oscilloscope you can see the waveform and its changes as a function of time, while a logic analyzer is particularly suitable for examining digital buses and signals. A spectrum analyzer is used to analyze the frequency content of signals.
In Partcon's current range of measuring instruments, Rigol, Owon and PeakTech are emphasized, and multimeters also include Fluke and Kyoritsu models.
