Your videos on this Fluke scopemeter are extremely helpful. Can you please answer a couple of simple questions about the functionality that I have not been able to find anywhere including talking to Fluke customer support? 1. When in the FFT mode does it compute and update the FFT in real time based on the continuous input signal? 2. What is the actual sampling rate when it is doing this -- I need 44 Khz for my application. Thank you.
