at time periods longer than 20msec/div, it seems that it automatically engages rolling mode and you can no longer set a trigger value hence a trigger event only can capture a max of 0.2secs
no ability to finely adjust vertical axis;
no rise time measurement;
cannot select specific probe settings other than from the 4 main configuration settings you can store
trace buffer limited to 60,000 samples
hence at 10msec/div which gives 0.1secs of capture, acquisition is 50000 per 0.1 sec (10 divs x 10msec = 0.1 sec capture) hence 500KSa/s is automatically used
and at 20msec/div which gives 0.2secs of capture, acquisition is 50000 per 0.2 sec (10 divs x 20msec = 0.2 sec capture) hence 250KSa/s is automatically used
no maths functions
no demodulation of signals - ie. no support for UART
high end scopes can be set to recognize the hex and even
ASCII content of serial data and can even trigger from a given hex value - this scope cannot do any of that
the simple FFT display does not offer any measurements you have to guess the frequencies based on position in the grid
the signal generator has limited output to only 5V and other limitations
spectrum analyzer has limited resolution at ~29kHz
reviewers have stated there are some software issues with spectrum and frequency response analyzers
