Keep seeing some of the ARM based scopes (agptek, jyetech, others): does anyone have any experience with anyone of these? Should I bypass these and just get an OWON or something similar?

Requirements are 2 channels, < $200, no PC needed, fast enough to watch PWM outputs going to servos and/or motor controllers, ability to trigger (as opposed to freerunning).

(or does anyone have a good working HP or Tekt looking for a new home?)

Did you see the DAQ for NI
Data acquisition (DAQ) is the process of measuring an electrical or physical phenomenon such as voltage, current, temperature, pressure, or sound with a computer. A DAQ system consists of sensors, DAQ measurement hardware, and a computer with programmable software. Compared to traditional measurement systems, PC-based DAQ systems exploit the processing power, productivity, display, and connectivity capabilities of industry-standard computers providing a more powerful, flexible, and cost-effective measurement solution.
