DSOX2024A stuck in endless bootup loop

I just acquired a used DSOX2024A that has a behavior I've not seen before: the scope starts its power up routine normally, with the sequential flashing LEDs, the splash screen with the MegaZoom chip in front of the outdoor scene, and then the black screen with the Agilent name and logo and the copyright notice. Then the screen goes blank and the boot sequence restarts from the beginning. It does this repeatedly until I power off the scope.

I suspect corrupted firmware may be the culprit, but I can't seem to find anything in the literature about how to reload the firmware if the scope doesn't first complete its bootup normally. Is there a way to force a firmware reload? Is this behavior indicative of some other problem?

Thanks in advance for any advice!

Stan

Correct Answer

Please try and re-boot the scope 5 times (if it's still stuck in the mode you describe, turn off and try again).

If you can re-boot, update firmware to latest version, v2.41, link below. This should stop it happening again.

If it does not re-boot, return the unit under warranty.

Have you seen this thread on Eevblog?

Even though your scope is out of warranty (I'm assuming it's the one that sold on Ebay June 6th) you might be able to get it fixed for free. Note the responses from Daniel, a Keysight representative.

Hi Jay,

Thanks for the pointer to EEVBlog.

Yes, you’re right. This is the scope that was on eBay. I posted a reply on the EEVBlog, so I hope Daniel will read it and have some encouraging news for me. Is there someone else I should talk to at Keysight about this, or should I just wait to hear from Daniel?

Regards,

Stan

Thanks for the info! I tried cycling the power many times, and also leaving the scope to run through its boot sequence for at least 10 or 15 cycles. Nothing I did would get it past the constant rebooting, so I sent it to Keysight last week for a "technical evaluation." I am waiting to hear back from them.

Regards,
Stan
