| Cheap and Small Dynamic Signal Analyzer? |

NanoDSA! |
| maxwell3e10:
AD4003 ADC and OPA828 input amplifier. Anyone has better suggestions? |
| Berni:
Sounds like a pretty good fit alright. Perhaps also add a DAC to also let it do frequency response or distortion measurement. Pair it up with a ST MCU with hardware floating point to do the FFT. The more gruntry ones are fast enough to do live real time FFT with no gaps at a few MSPS. Slap a LCD on the front and you got a NanoDSA. |
| electrolust:
always best to start from requirements. THEN decide the components. The hard part is going to be the software. |
| Berni:
Well if you are making something similar to the NanoVNA then the number one requirement is cost. Hence you just pick the best components that the BOM budget will allow and squeeze the best specs possible out of those. But yeah most of the work here is indeed the software. Its not difficult to do but a lot of work to give it all the useful features of a DSA. |
