Comment List
  • Hi All, and all roadtesters:


    Keysight has uploaded a new firmware for the E36300 series power supplies. You can download it here:




    Release DateVersionVersion Description2019-04-032.0.8-1.0.4-1.12Firmware revision 2.0.8-1.0.4-1.12 for models E36311A, E36312A, E36313A


    The release notes to the new version:



    Best Regards



  • Gerrit,


    You are right. I should share selection criteria when I receive it. I thought I had for this one. Maybe I didn't. My apologies.


    Most of the time, I am not give the criteria, just the selections. But I will make a point of sharing it with everyone when I do receive it.



  • Wow this would be amazing... I am currently using a 13.7v electric fence PS with some hand built boost bucks that allow me some control.



  • , this supplier information is very valuable, shouldn't this be communicated to all roadtest winners, It certainly will help to adapt the review to the expectations of the supplier.

    I also see value for those who are not selected, since it will help to write better applications in the future.




  • Thanks for the insightful and helpful response Randall.


    I'm not at all put off by not being selected for the Keysight E36313A Road Test. 

    I have been extraordinarily fortunate to have been selected for several competitive Road Tests over the last 6 years. Including, of course, the current R&S FPC1000 review that I am nearly ready to post.  No complaints whatsoever.

    My comment was an admonishment of what I thought was a strategic error on my part and a signal to others to think carefully about revealing purchase intentions.  Perhaps it was not a factor in this Road Test, but it could be a factor in decisions made by other vendors.


    Looking at the derision criteria identified by the supplier I'd say fell behind because of my nearly non-existent social media habits.

    Perhaps I view social media differently than many others,  In general, I have been unable to identify how I would derive personal value from most social media sites.  I sure can see how vendors look at this differently though.


    All the best.


    Mark A.

  • It's hard to say what goes through a supplier's mind when he or she makes the final selection for official roadtesters, There was only 1 time since I've been managing roadtests that I thought a possible direct sale played a role. But even that's a guess. Most of the suppliers are really focused on wanting to get a sound review. I don't think your desire to purchase worked against you. I had several interactions with the supplier. The person making the roadtester decision is very professional, customer-focused and I got the impression was looking at the big picture of how this new product would be viewed in the larger marketplace.


    For the benefit of you and any other roadtesters, I hunted for the email where she articulated her selection criteria. Here it is: "The criteria I used was based on how thoughtful/thorough they were in how they would use the power supply, whether they would appeal to the target customers, whether their application catered to the capabilities of the E36313A, and if my impression is that they would be on social media.  I also included quite a few runner-ups that were highlighted in yellow – just in case. You were right in that there were many good candidates!  It was really difficult to select the top five.


    I want to thank you for your purchase. We value your business. If you have a problem, make sure to contact me and I'll help resolve any issues.

  • You admission of willingness to purchase should not be held against you since it clearly indicates a willingness to use the device.


    My experience has been a mix bag as far as applications go and I believe there is no right formula for applications. In the past I have spent days writing an application only to be foiled later, perhaps for 'trying too hard'.


    The Keysight E36313A has it's share or issues as did the RnS RTB2K scope that has firmware bugs. RnS released firmware updates soon after we demonstrated the problems and I think Keysight will be able to do the same. As for the transients, those will be resolved in B,C,D... editions I guess. image This scope has a lot of niche features and I think you are in for a lot of fun. I will be sharing the Python library for controlling it in the next week as we are testing it and cleaning up the code.


    Good luck image

  • I hope it wasn't a factor, because I like the honesty - that should be rewarded.

  • Well, I didn't win this road test, so I followed through as stated in my earlier comment and bought an E36313A from Newark.

    It should arrive in a few days.


    I have been reading the E36313A reviews posted by ,, ,,and

    I am a little concerned with some of the transient mis-behavior, chassis handle damage, and firmware glitches that have been reported.  Hopefully Keysight is reading the reviews and is hard at work on a firmware revision.

    Maybe everyone's review efforts will contribute to the design of a new and improved E36313B. image


    Note to future road test applicants:  In my road test application for the E36313A I made it clear that if I did not get selected as a road tester I was going to purchase one of these supplies anyway.

    Although completely honest on my part, strategically, this admission likely caused my application to be excluded from further consideration.  From the vendors point of view it makes better sense to not send me a free E36313A when I have admitted I would buy one if I didn't get a free one.  Still, I think honesty is the best policy.

  • Hi,


    Yes, i understand you. I'll check it.

    I've seen also this but i didn't realize it first, thanks.
    But I must check some other things before.
    I think, Rachael have very fine images postet in her review, that's would describe a bit what you found out.


    Can you please also check this?

    -> It seems there is a software bug if i press the "back" button two times in a condition.

    This is what i checked afternoon during checking the functions of the buttons.

    - >> Preamble: the buttons normally are checked during a loop routine.
    So, if i press in "forward" condition the software works well. But if i press in "backward" condition (going upwards) the last "Back" pressing brings the software out of the loop into an "nirvana" -- seems into the endless loop.
    I've made a video for the documentation in my review.


    (Please, please, please.. sorry for my very badly English. I'm a bit nervous, excited.)



    This problem is not every time. Yesterday morning i found this error. Then i checked this some times but the PS worked many hours correct.

    I think, this error is coming out if you work with it together with the BenchView, also, or after disconnecting the USB cable. I don't know actually in details.

    So we have to check it a bit closer.


    Thank you.

    Best Regards
