Feb 19, 2018 · Sampling rate and FFT bandwidth, number of points are all very different for the two plots. You are comparing a plot of 50 kHz bandwidth at 100 kS/s and 131,072 points to one of 5 MHz bandwidth at 10 MS/s and 1M points.

Oct 5, 2018 · There's a 1000 USD 16-bit PicoScope presented by atomicbob@ here: https://www.superbestaudiofriends.o...analysis-systems-technical-measurements.4465/. There are also other measurement tool in there as well. Regarding the audio measurement usage, I personally find a scope perfect for: - finding phase delay for both sine and square waves

Feb 28, 2018 · First measurements were done with my Picoscope that showed a 35mV DC voltage on output. This is a respectable value for an amplifier that is able to push over 30V RMS on 8-Ohms speakers. I've seen headamps with 20-30mV of DC.

Aug 18, 2017 · Nelson updated Forte with more of the audiophile tweaks in later versions. 1a, while operating in pure class A mode, has a significant amount of negative feedback compared to its younger siblings. I had the amp on the bench to try to measure ultrasonic and RF interference from DACs into the amp...

Dec 29, 2020 · I usually test this with my PicoScope 2204A. It has a built-in generator and I compare 10 Hz square-waves from the generator vs. the DAC-output. With all of the DC-coupled DACs tested the 10 Hz was perfect or almost perfect.

Aug 6, 2018 · Note: I used a battery-powered laptop ans a step-down 230V-120V transformer to be able to use my PicoScope there and do this measurement. Usually, for our safety, we should never use standard probes when measuring AC mains, instead differential probes should be used...and authorized technicians too.
