Slow UI response for large FFT size

Slow UI response for large FFT size

Postby suktan » Fri Aug 14, 2020 12:08 pm

Hello Virtins team,

I downloaded the trial version and evaluating the software. One thing I notice is that the UI response will be very slow for large FFT (> 256k). Is it expected?

Thank you!

In our test on a DELL XPS 8900 desktop computer (Intel Core i7-6700 CPU@3.4GHz, 8GB RAM, 64-bit Windows 10), the screen refresh rate is 0.9 second/frame when [FFT Size] = 262144. The trigger mode is set to AUTO so as to eliminate any delay caused by not-satisfying the specified trigger condition. The sampling duration (Oscilloscope Frame Width) is set to 10 ms to make sure the delay is not caused by sampling duration.
