This mini scope is more than a plaything and would be quite useful as a second scope, especially when retro-fit regulators have been added to the power supply. At around €30 the unit is really low cost when you consider that includes shipping from the Far East. This value is above the EU tax-free limit for imported goods so expect to pay import tax.


Square Wave
Edges of the 1 kHz calibration signal (DSO150) are not as steep as you would expect from a quality scope.
