Despite its utility, the firmware is limited by the hardware's 200kHz bandwidth and 2.5MS/s sampling rate. Experienced users on All About Circuits note that while the firmware manages basic "noisemaker sniffing" well, it is not a replacement for a professional lab oscilloscope. Comparison with Successors
