Feature request:
1. Bode plot - Speed
The speed of the bode plot is awful, especially compared to other scopes on the market. Hopefully the implementation can be improved to increase the speed.
2. Bode plot - Phase unwrap
When measuring a circuit with output inverted compared to input, the phase jumps from -180 deg to 180 deg frequently, polluting the graph. Would be nice if the phase can be unwrapped.
3. Acquisition - Low/High/Band pass filters
My first oscilloscope, the Rigol DS1052E, which I believe is more than 10 years old, had fast Low/High/Band pass filtering performed (I beleive) in hardware, and is extremely helpful for characterising analog signals, which I believe is what 12-bit scopes are really for. I really hope some form of LP/HP/BP filtering function can be added to the scope.
4. FFT - Logarithmic X axis
Would be very helpful to get an option to display the frequency scale in log scale, so that lower frequency content can be viewed more clearly on measurements spanning multiple decades.
5. FFT - Power/voltage density Y axis units (dBm/rt Hz, V/rt Hz)
Given how low noise the front end is, and with a 12 bit ADC + hardware 3-bit ERES, makes this instrument great at analysing noise - potentially. Having the ability to display Y-axis in units like dBm/rt Hz, V/rt Hz in addition to the Log X axis feature requested above, would turn this instrument into an alternative to dynamic signal analysers (DSA). Hopefully Siglent can be the first to be able to do this, given their recent launch of multiple 12 bit scopes, I'd actually happily pay for such a software option
