Siglent SVA1015X and SVA1032X 1.5, 3.2GHz Spectrum & Vector Network Analyzers
antenna:
Anyone know the size of the file it writes? If it is like they say and writes to a new address each time, I imagine by the time it cycles through whats left of that 2Gb of storage and repeats that 100k times, we will all be dead anyhow.
Johnny B Good:
Actually, that highlighted in bold statement was precisely what I was trying to get across to IM3. I thought rewording it might help convey the meaning of Siglent's message.
dmytre:
After several months of operation, the reflection coefficient at the startup of the device looks as shown in the attached photo. The device in VNA mode can still be calibrated, but the dynamic range has decreased to S11 levels of -15...-20 dB. Has anyone encountered a similar issue?
IM3:
Try checking if you have the correct levels in spectrum analyzer mode. It's possible that the input is blown.

I think you misunderstood and missed the highlight portion below:
This file system has a balanced management of Flash, which means it is NOT writing to the same physical address.
Our application determines whether the configuration has been modified, and if not modified, it will not be saved.

I’m genuinely trying to understand this.
It seems to me that the configuration changes almost immediately after powering on. The settings are probably adjusted right away—that's just how it goes.
I’m willing to believe that the configuration is stored in RAM, although Siglent doesn’t say that at all in their response. And how do you quickly save it to Flash during a power-down?
After that, I don’t understand what problem Siglent thought they were solving with this option. I could already choose to use the last configuration at startup.
And now Siglent is even saying that in the next update, this new feature can be turned off again.
( sake of the discussion, nothing more.)

A reverse variant of all the alternative descriptions used by the disgruntled customer in the Monty Python "Dead Parrot" sketch as in "This flash won't be joining the choir invisible any time soon". :)

Tone can be hard to discern in written text, and it’s possible you intended it as humor rather than criticism. But it might also carry an undertone of "explaining things to someone who doesn’t get it."
And that doesn’t feel right, especially when Tautech follows up with a “Thanks.”
That shouldn’t be the tone we have here.
