JonP:
Been quite a while since last FW update,  just did the following and have the same positive experience,  though haven't given it a good shakedown yet....

But,  wondering about the following statement, regarding the changelog comment.  Has this been verified?

So,  my question,  I had everything unlocked,  from long ago,   and thought I wanted to set to DSER, to turn off the 500uV feature.  Sure enough after the firmware update everything was still turned on,  went to the site, got a key for DSER,  applied and...   everything is still set on,  including the 500uV.   I'm forgetting if you need to re-unlock features after a FW update.

Did I miss something,  or does the 00.04.05.SP2 FW remove the ability to change what features are set? (after turning them all on?)

Fungus:
DSER won't re-lock anything.

What you need to do is remove all options first then apply DSER.

Connect via telnet and type ":SYStem:OPTion:UNINSTall" to remove everything.

RoGeorge:
When you added the 500uV option, the already existing options were preserved.  Once unlocked, the options will remain unlocked after a firmware update.  It is not needed to re-unlock after a firmware upgrade.  Firmware updates does not disable the existing options.

The only thing needed after a firmware upgrade is to run a self calibration (from Utility -> Self-Cal).  Before doing a self calibration, unplug all the probes from their BNC connectors, and let the oscilloscope running for at least half an hour for internal temperatures to stabilize.

JonP:
Figured...  Never saw it explicitly stated in my reading around,  but was starting to get the idea.  Kind of expected that setting the DSER would overwrite the original,  but that's what happens when you expect vs experiment...

I take it that having the 500uV feature on doesn't cause any problems, other than unreliable vertical readings when you use it?  I'll still clear it out,  of course.  Probably recal again too,  so it doesn't try to cal the "500uV" setting.

Off to do some Telnetting...

It's obvious if you think about it: When you buy a code to add a new feature you don't want it to remove any existing features when you apply it.

I think the whole problem with the 500uV setting is that self-cal doesn't calibrate it. That's why some people say it works and some people say it doesn't.

It's not a good idea to enable it though, IMHO.
