Will make sure we post this on the Keysight thread
Why? Releasing equipment with multiple bugs fixed through multiple firmware updates is not something their target customers envy
Siglent’s response time is impressive though. They work really hard to win our hearts and minds
If you think Keysight has no bugs you are sorely mistaken.
I found a bug in MSOX3000T network stack where certain series of Internet routers would respond to scope with some weird packet during DHCP process where scope was trying to get IPv6 address while router had IPv6 protocol disabled.
Instead of scope ignoring it and not configuring IPv6, scope configured network stack into some weird state that it would hard reset the scope when trying communicate over network.
First time it happened it looked like something was wrong with memory on mainboard and that scope is done...
Response from Keysight was that they know the problem and they couldn't be bothered to fix it, or even to put in a config option to disable IPv6 for people that don't use it (99% or people on internal networks).
"
The lab team will look into if it’s technically feasible to add an option to Disable IPv6 on the scope, however it’s not a priority and will most likely not happen.
As far as how to proceed, we appreciate Your offer to capture router-scope traffic, however since our labs team are busy with other priorities, we won’t be pursuing this further at this time.
"
So yeah, Keysight has bugs and they are fixing them when it is
their priority.. My fix was that I had to buy a separate router and add it to the network... Scope bug is still there.
Releasing equipment with multiple bugs fixed through multiple firmware updates is exactly what Keysight and R&S and othe A brands do, like many others today...
The firmware release document for 3000T is 18 pages long... Read it to see how many bugs were there and how long it took to fix them.
In everybody's defence, scopes are so complicated today and they cannot have time to market of 10 years..
What matters is that bugs are fixed. And A tier manufacturers are not that perfect in that as many think.. At least not if you are not on multi million contract with them...
OTOH, on other occasion I mentioned that MSO 3000T was missing pulse count measurement on digital channels (it had it only on analog ones) and they added that measurement on next firmware (some 10 months later, when they pushed it for some other reason)...
So Keysight are not bad but far from perfect.
OTOH I find Siglent's effort to be first class and they are working harder than anybody else including many A brands...
