• M1 Oscilloscope Tools supports more Tektronix scopes than JIT3 does, and of course, more LeCroy, Agilent and Yokogawa scopes.
• Some Rj/Dj capability is included. But it doesn’t do error calibration, does not calibrate instrument noise out, is not validated over a broad jitter space, has no convergence/divergence detection and does not specify it’s typical error in detail as M1 OT does with the Decomposition Performance Explorer (DPE).
• Eye-diagram package: $7500
• Compliance tests are “extra” - $995-$7500 each.
• Debug – very limited compared to M1 OT.
• Automation - No ability to automate sequences of measurements or add measurements. M1 OT has ScriptBuilder™, a great graphical tool for doing this easily.
• Productivity – nope.
• Portfolio – no offline analysis or no client/server (M1 Reader), no LabView.
• Product philosophy things – No scalable pricing, proprietary, not portable, fine-grained á-la-carte-ing (i.e. you pay for the sugar), and it costs more to own because of these things.
• Not shown here – Wave Inspector adds some additional but limited debug (2 limited and 1 unlimited cell in debug area), and is available only on select scopes.  
• Summary vs M1 Oscilloscope Tools: JIT3 costs more, does less
