Great little scope with big features on the inside for a great price.
Very stable views, great triggering options, great storage and compare of previous measurements.
Replaces my larger, slower, much more expensive FL**K 123 A scope.
This scope is very difficult to understand, not recommended for automotive applications.
This is NOT a 72MHz bandwidth scope. It is rated at 72Msps or 72 mega samples per second, but it is really two 36Msps ADC channels. That is shared between the active channels, so if you have all four channels running, it is down to only 18Msps.
I gave this only 1 star because it is NOT a "72MHz analog bandwidth" scope. As a 4.4MHz scope, I would give it 4 stars. I'd leave off the last star because of the rotten documentation, nonstandard connectors, crappy sine wave on the built-in function generator, and difficulty in figuring out how to update the firmware.
An analog signal like a sine wave requires -at- -least- 8 samples per cycle, which puts this at about 4.5MHz with all four channels going.
This is born out by the antialiasing filters on U17 and U18 on the two analog channels which have a -3dB cutoff of about 4.4MHz. That goes for -everyone's- DSO203.
It is important to know that channels 3 and 4 are digital only. I think they...
