Impressive feature set for entry level low cost oscilloscope.
I got it to view I2C communications in decoded trace through protocol analyzer. I was not putting a lot of hopes, but now I find it impressive as a replacement of any analog scope in everyday lab for signals running at below 50MHz. The feature and measurements included are great, the analog persistence on display is appealing, and best of all, it can be remotely controlled through National Instrument tools over Ethernet. A less convenient remote scope panel is also available and may be very handy.
The scope does not have a trigger input and operates its triggering exclusively from the samples of ADC.
When not all memory is used for a single shot, the scope combines several traces for "better resolution". They are using some post-acquisition trace alignment, so in this mode one may see weird pictures on display in some corner cases, but for baseline measurements it is fine. I thought it was using a more sophisticated front end amplifiers as in other 1xxx series, but this one is pretty baseline. The sampling rate with 3 or more channels is 250Msa.s, so it is good that the bandwidth is limited by ~70-100MHz.
In summary - this is a great instrument for hobbyist, student, maker and everywhere when working with mid-speed analog and digital circuits and Arduino-style microcontrollers.
