Unfortunatly we can see this kind of stuff happening with basicially all big players when it comes to the modern, digital driven testgear. Tens of thousends of dollars for an MSO Series 4, RTM3004 or whatever - the first firmware releases were spicked with bugs. Pressure to release new products seems to be to bug to hold back until this kind of stuff is fixed... ;/

But in the end rushing out new equipment is doing nobody any good because people will be wary of new equipment and postpone purchases.

You previously claimed that you get something that Just Works and meets specs when you buy A brands.  That they do proper QA and fundamental functional problems thus get caught before release, and that this justified their higher price.  Do you still stand by that?   Because it looks to me like that's becoming less true as time goes on, if this thread is anything to go by.

Well, one of the lines I wanted to add to my previous posting is 'If A-brands are going to be consistent in this behaviour then people might as well buy gear from Rigol or Siglent'. It is already a fact that A-brands push out equipment ahead of schedule and need about a year to fix firmware bugs. IMHO it is still worth buying an A-brand due to pedigree; the core of the instrument usually is based on old & well proven designs / methods so it will also work in the corner cases where gear from Rigol & Siglent typically fails. Due to the latter I decided to leave the line out.

Have Keysight responded this at all?

Nctnico made some valid points, however the MXR last year was another case in point of being released far to early at that point in time imho

Haha  ;D

I'm passing this along to the team for feedback!

Makes sense.  Do you have some examples of where an A brand handled a corner case where the B brands failed?

I also get the sense that the A brands tend to be constructed better than the B brands, though I think the B brands have been improving their game a bit on that as well.

Siglent SDG2000xyz function generator versus Tektronix AFG31000 for example. The latter stays in phase with an external reference when doing modulation. Also the Tektronix AFG31000 is a true stand-alone unit. You don't need any PC software to edit / import arbitrary waveforms.
