The s(M)exoscope also contains a tool that can be used to analyze the waveform currently in the display.
SMEXOSCOPE ANALOG SOFTWARE
Now a conventional sound card will be limited in measurement range, may not be well referenced for absolute measurements, and doesn't have the input/output protection test equipment usually provides, but it could be a free plus whatever software you choose option to accompany and augment your scope purchase.S(M)exoscope is a free oscilloscope VST, Audio Unit plugin developed by Smart Electronix. If you want high resolution, low noise audio equipment, a lot of dedicated equipment for it will be very, very overkill, and performance of even a decent sound card will probably be better in the audio band (probably 16+ effective bits) than most scopes or similar.

SMEXOSCOPE ANALOG PC
That said, if you're sticking to audio frequencies, you may be fine off with a decent PC sound card (USB, often) and some measurement software. If you don't have a scope then getting one is probably a higher priority than measurement resolution/noise floor - it's a versatile tool that will be widely applicable beyond this application. It's a dynamic signal analyzer, purpose designed for sound and vibration testing, but they've basically been discontinued given the availability of audio analyzers on the high end and simple sound cards on the low, so you can find older ones for fairly cheap, but there's few new direct comparison products. I would be glad if you could give me some advice on the mentioned models or could possibly give me alternatives that meet the desired requirements. In addition to the SDS1202X-E I found two videos that show signal distortions at low frequencies: The low-frequency range is definitely relevant for my application. On paper, the Siglent SDS2202X-E looks like a clear winner, but the device is pretty new (means buggy?). With these specifications in mind, I've selected the attached models. Therefore, in my preselection, I have included only models that have this feature.
