New firmware for Keysight 3000T and 4000 series scopes - version 7.11

[mikeselectricstuff]

Another bug - the horizontal scale offset is incorrect  when you set the time reference to left or right.

[TheSteve]

Mike - you can try the newer version of 7.10 - maybe the second bug was fixed.

Will there ever be an FRA option available for the 2000X series? All the other MZ4 InfiniVison series have one now!

[mikeselectricstuff]

Just updated to 7.10.2017042905 ( was 7.10.20171130), no difference

I can confirm this issue, I have noticed it as well after FW update.

[mikeselectricstuff]

The custom splashscreen function seems to no longer work - attempting to load a 800x480 image (MSOX3104T) , it displays about the top 384 lines of the image, immediately, vertically stretched and says "do not know how to load the selected file".
The display is then garbled - with parts of the image overlaying where the traces should be

Wondering if maybe it's looking for a different resolution?
Have tried PNG and BMP

Do you mean boot screen image? Custom image still looks fine for me.

Boot-up time seems to take less time. IMHO MSOX3T booted a bit slower with previous FW.

I'm talking about adding a custom screen to a unit that did not previously have one ( e.g. after secure erase), not a previous image after a FW update

Is this a bug?

Digital channels seems to be shifted to the left.
WaveGen set to Pulse, 2.5Mhz, 50nS width and feed into channel 1, D0 and D1.
Trigger set to rising edge on D0 and in center.
The trigger seems to trigger right but the digital waveforms is shifted to the left by about 144nS and there is something strange going on to the right of the screen.
If I change the timebase the signal is still 144nS before the triggerpoint.
Don't know if this was there before the update but I haven't seen it before.

Have you checked the analogue probe skew setting?

[rattnallen]

Yes, it's 0.0s and the thing is that the analog channel is on the triggerpoint but the digital is not and the trigger is on D0...
And there is a 144nS difference between analog and digital channels and the max skew settings is +-100nS.
And the strange right part of the digital channels? The scope is in autotrigger and in run mode.
If I stop it, the strange right part goes away, but the digital signals is still 144nS to the left of the triggerpoint.

[Amazing]

Wow, I am really glad that I held off on applying the firmware update.

Thanks to those brave souls who did the upgrade and found these bugs.

I'm still hoping to hear back from Daniel about whether the new manchester encoding option will decode and trigger on SMPTE LTC timecode.

And still not happy about being asked to pay full price for a new serial decode after buying the full package of options in December, when the full options package price has not changed at all.  At least make the new options available for a small package upgrade fee ($200?).

Am I unreasonable to be annoyed by this?

I could understand it if it was some completely new complex feature like e.g. a jitter analysis package (which would be awesome to get on the 3000T, by the way).

[mikeselectricstuff]

Just confirmed I see the same thing - digital channels 130nS early. My scope has just been calibrated by Ketysight, so not a drift over time

[rattnallen]

Thank you, mikeselectricstuff 

A rather serious bug, I think.

[mikeselectricstuff]

I just plugged in my 1152A active probe and it's now saying "unsupported probe".
I have a feeling this probe had some mods and possibly an eeprom tweak, but I'm 99% sure it worked on an earlier firmware version

Does anyone have a copy of the previous firmware version ?

Just tried my other probe and it appeard to work, so could be an issue with that probe.

[TheSteve]

The 1152A isn't natively supported, the scope reads it as a 1157A or 1158A - the scopes can be a little picky at times. You can always try cleaning the contacts or worst case connect the probes and then power the scope on.

[D3f1ant]

Yeah 144ns early here too >sigh<

[Amazing]

I have a copy of FW version 4.08 (3000XSeriesT.04.08.2016071801.ksx), ~53MB. Would it possible and safe to downgrade?

Were any of you able to successfully downgrade your firmware?

[Keysight DanielBogdanoff]

The bugs have been reported to R&D, I'll update as appropriate. Thanks!

[Keysight DanielBogdanoff]

7.11 will release next week and fix this issue along with a couple other reported bugs, I'll post the update and release notes as soon as they're finalized.

Great news, thanks for the update.

[adranp]

I can confirm 100% downgrading works between 7.10 and 4.08. I did it and it was painless..

7.11 has now been posted on the Keysight website.

Also seems to have fixed the custom splashscreen issue.
But the grid scale text is still too dim.
