"good" is a subjective term. I would say it is superior to the Chinese version of some software that many FY3200S users initially received, but in reality it is far from complete. It is more like alpha software thrown together for a targeted user base to provide feedback to its developers.
I have been experimenting directly with the device sending commands via a terminal program in order to better understand how to control the device and what can and cannot be done via the front panel and the USB interface. I am using information gleaned from this post and several other sources. I am discovering all sorts of interesting behaviors. For example:
1) Is is not possible to set the phase angle of the CH1 waveform via the USB interface, but it can be done set though the UBS interface.
2) The internal counter rolls over at 268,435,456 (2**28-1).
3) ... the list goes on.
Right now I am trying to understand the trigger options. I am stumbling around trying to understand what these options do and how to to use them. I would appreciate if someone could provide some clarity. What is the relationship between the counter and the triggering options?
