* Not actually 4 channels. 2 O-scope channels, 2 digital inputs. * Asylum has one, as well as a pile of the single-channel version. * Distortion is terrible. 72 MS/s is an egregious enough exaggeration of something that is technically true that I would be tempted to punch their marketing guy in the snoot. * Better than nothing. Marginally.
