That song is getting old. --- End quote --- Is this link spamming is happening on other Keysight threads? --- End quote --- Where someone suggests that individuals may be interested in a product but the company does not support individuals, I think a single warning is appropriate. That's similar to warning people not to use float scopes every time someone suggests doing that. N.B. as someone that was very appreciative of HP support policies, and who worked happily for HP for 13 years and loves HP kit, the Keysight attitude pains me. I think it deserves to be mentioned when appropriate. --- End quote --- The thing is that only a few people have reported this who all seem to be in the UK while others (like me) have no trouble at all getting support from Keysight. You have to keep in mind that this could be single incidents related to people's attitude and/or the question being asked. And even if Keysight doesn't give direct support, you can always get in touch with the dealer that sold you the equipment. IMHO there is a lot of parroting from some very vocal people and very little substance. No need to pollute other threads with stories that could even be classified as 'fake news'. |

I prefer less belligerent terms whereever possible. There is no known reason precluding Keysight extending their policy to other countries. If, OTOH, they become forthcoming about why they (abruptly and without warning) changed their policy, then I will be delighted to change my opinion. Absent that, our opinions will differ. |

Switchers also do constant power trick. 80 A PSU is not going to be linear, and noise proves it.. --- End quote --- I agree. It is nice to see though that Keysight brings this old concept back to life. In the HP days they used to have a whole bunch of these kind of supplies that have a power limit. It makes a PSU much more versatile. I have a pair of HP6012As which are excellent for when a lot of current or high voltage is needed (and the power limit is kind of a conservative estimate). Still, I would like some more modern metering though. --- End quote --- This looks like a very close competitor to the Aim TTI QPX750SP, continuing their range of "powerflex" supplies. Pricing will be key as always. --- End quote --- Yes and no. For the Aim TTI PSUs it seems you need to use PC software for the more advanced functions while the Keysight PSUs allow to do all the programming on the PSU itself. Personally I'm a great fan of test equipment that can be used to the fullest extend without needing PC software. Recently I needed some voltage sequencing and that is easy enough to configure on the Keysight E3631x series PSU. |

Especially when it doesn't apply to everyone. |

Especially when it doesn't apply to everyone. --- End quote --- Agreed. But I don't see it on every thread, only on occasional threads where amateurs are directed towards new Keysight equipment. The difficulty is the whole thing is a big grey area. Other examples: * the maxim "friends don't let friends use Maxim". Very difficult to provide an unassailable justification for that one, nonetheless experienced engineers repeat it! * "never float a scope", which is sometimes written in large unfriendly red letters |
