Siglent SDS 1202X-E sampling anomaly?
Performa01:
Screen height is just 200 samples, the rest is overhead. As a consequence, there are 25 samples per division. At 500 mV/div we get 500/25 = 20 mV per LSB. Unsurprisingly, we get one LSB per division at 20 mV/div. Neither does this look pretty nor does it make much sense for any measurement.
Vector display mode has two sub-modes:
* linear interpolation
* sin(x)/x reconstructionMake sure you have sin(x)/x selected instead of linear.
Average acquisition mode combines several acquisitions into one single data set. With 4x averaging we gain two additional bits of resolution. In higher class scopes we have a limit of 16 bits at the moment. If the same is true for the SDS1202X-E, then averaging up to 256x can be used in order to get a 16 bit acquisition. This will take some time though, because this acquisition mode is not HW-accelerated in the SDS1000X-E series.
