The Cherry Audio / MRB VM2500 module 1019 Oscilloscope is a versatile dual-trace scope modeled after analog units of the 1970s. The 1019 is one of several modules ARP planned to add to the 2500 line, but unfortunately never did. There is no detailed description of what this scope might have been like, so this is our take on it, and it's likely far better than what was planned. The 1019 has features found on high-end scopes such as AC/DC coupled inputs, calibrated sweep and vertical amplifiers, single-sweep mode, and variable level triggering from either of the two input channels or an external source.
