--- Quote from: Fungus on October 03, 2022, 08:46:29 pm ---Another option would be a modern Micsig oscilloscope combined with Analog Discovery for the bode plots. :popcorn: Micsigs are a joy to use. (it's what I own) Analog Discoverys have a 14-bit ADC for the bode plots and can also do logic analysis for your Arduino. Edit: You can download the Analog Discovery software and use the "analog" part for free with your PC sound card. It does oscilloscope, spectrum analysis, bode plots... --- End quote --- Micsig scopes don't even have statistics in basic measurements. Or segmented capture in their lower priced models. It is very nice and useful portable scope and that is it. To be honest, what is all this high recommendation for AD2 as a FRA device. I know it has Bode plot functionality but despite it's nominal 14bit resolution, it has only 2 measurement ranges. What is actual performance of it performing stability analysis on a switcher PSU? Dynamic range and complete amplitude range? How well it performs in presence of noise? I searched and found no real performance figures in real world scenarios.. I also found some claiming problems : https://ashwinschronicles.github.io/analog-discovery-2-labview-home-bundle-review So what is real performance of AD2? |

I can't say I've missed having it since I traded in my Rigol. :-// The Micsig is way faster/easier to use, I don't regret the loss of a few "checkbox" features at all. |

I wasn't aware anybody here was considering it for stability analysis on a switcher PSU. I was thinking more that OP wanted Bode Plots and had mentioned wanting to do it on his 27" PC monitor. |
