Quite the opposite.

I'll see what I can find out.....if not immediately, in a few weeks when I visit HQ.
However, I personally deal with many NAND failures worldwide and have a multitude of recovery packages to repair problems with NAND management which are getting less by the day.
I can in no way see Siglent changes to SVA/SSA SW impact on NAND wear as they are very conscious of these issues.
I like you highly value SVA and it's my fav RF instrument yet have never had or seen problems with NAND wear in any Siglent analyzers.

I would like to come back to the topic of saving for 60 seconds.
A few months have passed now, but there is still no official statement about what exactly that means.
@Tautech
Were you able to find out anything about this at HQ?
EE4all:
Any update on the flash writing every 60 seconds? I am holding off on the firmware update until this is clarified.

I too am hoping for a response here. Mine has been, for the most part, unplugged since I did this upgrade to make sure it does not damage my 1032x. I assume one way around this is to not have the power on option set to "Last", and if the feature is wanted, it could be switched on just prior to turning off the unit. PITA though, always having to go switch it on and off.
antenna:
I just turned mine on to change it from last to user and noticed it would freeze in SA mode after one sweep. The little red crossshair would get to the end and all functionality just stops. I had to quickly change it to VNA mode before the sweep finished and then find the factory reset in the menu. After the factory reset, a SA sweep between 1 and 30MHz resulted in a sawtooth noise floor. Thankfully after powering down and restarting again, it seems to be good. This is ridiculous though, I still have 53 hours on my trial features. Barely used and already having issues.
IM3:
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
And the American headquarters at : support@siglentna.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,
