Hey guys, I am currently looking for a cheap audio anaylzer and oscilloscope to quantify results of amplifier and dac design. Aswell to mesuer the impact of Bluetooth Aptx HD codecs.
Unfortunately I am on a really tight budget so instead of buying the correct tools like a real audio anaylzer. I want to minimise my risk and buy things that have a dual purpose like an audio interface. Worst case is I fail at designing, then the interface can just default back to a normal audio interface for my audio tecnica condenser mic.
Enough introduction here is the short list of audio interfaces I have compiled.
MOTU M2
120 USD
DNR: 115db
THD: -97db
Noise: -128db EIN
Max Input:VRMS 2.449V
Focusrite Solo gen 3
111 USD
DNR: 111db
THD: 102.5db
Noise: -128db EIN
Max Input: VRMS 2.183V
Komplete Audio 1
109 USD
DNR: 109db
THD:
Noise: -128db EIN
Max Input: VRMS 2.4524V
Focusrite Clarett 2Pre USB
296 USD
DNR: 119
THD:
Noise: -129 EIN
Max Input: VRMS 8.7014

449 USD
DNR:
THD: 108.5 db
Noise: -113 db
Max Input:VRMS19.95V
I'm leaning more towards the focusrite products. Again I don't want to spend much money so the solo seems to be winning right now. The 2pe is at a very good price locally so I'm getting tempted. Does anyone have any other recommendations? Is the 2pre really worth 3x the price of the solo?
I will need to aquire a audio attenuator and a decent oscilloscope.
More research needs to be done on audio attenuation. There doesn't seem to be much discussion on ASR. Does anyone have some useful information on this?
For oscilloscope I have a short list aswell
OWON XDS2102A 12 Bit Oscilloscope
Hanmatek DOS1102 Oscilloscope
OWON XDS3064AE 14 bit
Hantek 5072P
I currently own a really terrible hantek USB oscilloscope (6022be). It's absolutely awful, full of noise and terrible software. Ideally I would avoid USB scopes, I looked at the picoscopes as they can apparently get to 16 bits but I have little evidence of there noise floor so I'm not sure on them plus they are crazy expensive but if they can do everything in 1 package then they might be worth it. Also I'm ideally looking for a Higher vertical resolution and a low noise floor on my oscilloscope to do basic fft measuernts to check for oscillation, measuer power supply ripple and do basic fft analysis. I think I will need up to 100mhz but I might need 200mhz for dac design. Some of these dacs such as the new ess dacs need a external 100mhz crystal oscillator.
Any recommendations would be welcome aswell.
