I am curious if someone would be able to write a custom firmware for the DSO201/DSO203 mini oscilloscope so it can be used as a a mains power analyser (with appropriate divider probes), with the following features:
* Measure frequency and voltage as well as harmonics and noise with or without a current clamp attachment (current clamp can be configured) - power factor can be measured with a current clamp attachment (again, user configurable).
* Record as many harmonics as possible (ideally, 50 at least) in a table with THD and noise and graphically.
* Measure mains frequency deviation against a user set frequency.
* Log to memory card on power disturbances (power failure, sag, surge, undervoltage, overvoltage, transients, line noise, frequency deviation, harmonic distortion etc. with user-configurable thresholds) and/or during preset periods of the day of the parameters mentioned above.
