Just a bit of fun…I try use an oscilloscope to measure / calculate the speed of sound. I also conduct a hearing test during the video.

A catch for some new folks – Performance (waveform updates per second) drops off if you have a large enough horizontal offset / delay – this happens on most scopes.

The Keysight / Agilent struggles to Auto trigger on less frequent pulses. This is due to their Auto trigger rearm timer being very short…because the scope is fast.

The Keysight has a set of 5 GSa/s ADC’s and MegaZoom IV ASIC’s paired and hardwired behind channels 1 & 2 , 3 & 4 respectively.
This means that if you are only using two channels and you select 1 & 2…the sample rate is halved to 2.5 GSa/s and so is the waveform update rate. You need to select channels 1 & 3 to maintain the higher performance and sampling rate.
The Tektronix MDO3000 series allow you to select any two channels and maintain the higher sampling rate.

The new time correlated FFT (frequency domain) feature (FFT Gating) with a time domain signal suffers from a harware problem. If too much data is being parsed in the zoomed mode with FFT Gating, the FFT funcion will stop / hang / freeze.
