Portable oscilloscopes of the HPS series of the Belgian company Velleman are not graphing multimeters, but modern portable single-channel oscilloscopes at the price of a good multimeter. The high sensitivity of the devices and the extended set of functions make them ideal for both radio amateurs and industrial applications.
Fully auto-swept waveforms greatly simplify analysis of any waveform.
