Hi All, I was trying to continuously log some signals using an FX2 demo-board. And I noticed a big difference the number of samples recorded on Win7 and Fedora23, 250kS and 200MS respectively.
This was at a sample frequency of 200kHz, using a sample frequency of 500kHz, around 650kS were received. Trying the same on a i3 Win7 laptop resulted in roughly the same the numbers. A 7inch Acer with an Atom cpu wasn't able to compete. Then I tried an old i7 desktop, it receives 410kS, and 1MS respectively. This was all recorded using a python script which repeatedly called sigrok-cli with a new filename. So this is where I thought the problem was maybe my python script, so I tried manually on the old i7. But manually was worse!, 320kS and 810kS respectively. Note that I just reinstalled sigrok-cli and the zadig driver. So I would think the new libusb patch would be included. So is 't possible to get the performance I got using Fedora 23 on Windows? Maybe some simpler questions: Why is a sample limit of 1T invalid using the command-line, but it is selectable in PulseView? And is 't possible to 'continiously' measure (like my script) with sigrok-cli, i.e. without restarting sigrok and overhead associated with it? -- Greetings, Henk Hendricks ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
