Oscilloscopes

Oscilloscopes are grouped here by form factor: benchtop digital storage scopes, handheld and battery-powered units for field work, PC-based instruments that use a laptop for display and storage, and the probes that determine what the scope can actually see.

The range covers Keysight, Tektronix, Teledyne LeCroy, RIGOL, Siglent and Pico Technology. Bandwidth is the headline number but rarely the deciding one. Sample rate, record length and the number of channels usually matter more, especially for serial bus decoding or capturing an intermittent fault over a long window. Probe selection is the most commonly overlooked part: a 200 MHz scope fitted with a 100 MHz passive probe is a 100 MHz measurement, and current, differential and power-rail probes each change what is measurable. Tell us the signal, the fastest edge you need to resolve and whether the work is on a bench or in a plant.
