The 60-second Flash mystery has yet to be solved.
So, I decided to contact Siglent via email and hope to receive an answer any time soon.
I emailed the European headquarters at: info-eu@siglent.com
There is also the Asian headquarters at: sales@siglent.com

Subject: Concern Regarding Firmware Update V3.2.2.6.2R5 for SVA1000, SSA3000X Plus, SSA3000X-R Series Spectrum Analyzers
Dear Siglent,
I would like to share my concerns with you regarding the firmware update V3.2.2.6.2R5 for the spectrum analyzer series SVA1000, SSA3000X Plus, SSA3000X-R.
In the firmware release notes, the following new functionality is mentioned:
“Save the configuration every 60 seconds, and load it when Power On is turned Last.”
On the EEVblog, users have expressed their concerns about the meaning of this statement.
The only reason to save data every minute would be for power-down purposes, which must be done in non-volatile memory, such as flash memory. The concern is that flash memory has a limited lifespan and will degrade after approximately 100,000 write cycles.
This would mean:
100,000 write cycles / (24 x 60 minutes) = 69 days of operational time.
It would be quite unusual for Siglent to write data to flash memory every minute, so I hope this was simply a case of poorly worded release notes that are being misunderstood.
Currently, many users are refraining from installing this update until more details about this issue are clarified.
I look forward to your response, which I will gladly share on the EEVblog forum.
Kind regards,
