I want to take continuous trace data every 500 ms. I go to level? -> trigger -> and turn on auto save and set the interval to 500 ms. I believe this should give me what I want. However I do NOT get a new save every 500 ms.? I get a new save about every 30 seconds. Why is this? What settings should I change?

Thanks,

Any input on how to save traces every 500 ms would be greatly appreciated. I've messed with all the settings to no avail. My best guess to to try to write a python program to tell the tinySA to save every 500 ms. Again any thoughts on solving this issue is appreciated.

0.5 s is too quick, slower is possible

The fastest I have been able to get it to save is in 30 second intervals. Is faster possible? Would this require going into the internals settings? I can manually press save twice faster than 30 seconds, so I know the system has the capability to save data faster than 30 second intervals. Thank you for your response.?

Basically I want to save continuous traces as fast as the TinySA ultra allows until the SD card is filled. With the autosave function the fastest it goes is 1 save every 30 seconds. When I manually press trace to SD I can create a new save about every 3 seconds. My scan time for the desired data is 270 ms.? What settings can be used to make the autosave function run as fast as possible? I am not worried about using up the entire SD card rather quickly. I actually expect this.??

Best to you and thanks,

James

Hi Erik,

?

I have tried to all options that I know of to get the TinySA Ultra ZS405 to auto save traces as fast as possible. The best I can get is every 30 seconds. There seems to be a hard cutoff in the code that doesn't allow the autosave to work any faster. Would an old firmware not have this issue and allow continuous autosaving? If I can get the autosave function to work every 3-5 seconds (faster would be better) I would like to buy 10 or so tinySA's for a fun project. If you have any knowledge of how to make the autosave function faster your input would be greatly appreciated.

Thanks again. You developed a very interesting device.?

The source of the tinySA is on github.

You can change this value in the code and build a new FW

Thank you. I think I found the line in the code to edit.?

Thanks again.?
