Why software do the 168xx frames use? Do they use Agilent LPA?
There’s info on this forum to generate your own licenses to enable whichever options you require.
This is easier than dumping the EEPROM’s, but that’s also a valid technique.
I think on the 16910A’s it was U102.
I’ll have a root around for the EEPROM dumps if they’re of any use. I had two 16910A’s with a variety of configs. But I definitely upgraded one to the max mem and speed with enough perseverance.

Yes, 168xx do use Ag LPA.
There are some differences between those families. In example 168xx MB bios is locked, so you can not replace motherboard, different eeprom content? for the same HW option and propably many others.
Did You mean "generic flexlm crypt generator v0.5 by haldir"?
Do You have one? I can not find it. All links that i could find are dead.
Gerald:
same question here!

The Agilent {16804A, 16806A, 16821A, 16822A, 16823A} analyzers are essentially exactly same hardware as an Agilent 16901A mainframe which is populated with {(2x) 16911A, (2x) 16910A, 16912A + 16720A, 16911A + 16720A, 16910A + 16720A} modules. (A 34-channel 16912A module does not exist as a standalone 16900-series product). They both use the same Intel D915GUX, ADLINK M-880, or ADLINK M-890 motherboards. The only real mechanical difference is that the 16901A has a module shroud for removable modules with ejectors, while the {16804A, 16806A, 16821A, 16822A, 16823A} analyzers have a module shroud for two modules screwed in without thumbscrews or ejectors.
The Agilent {16801A, 16802A, 16803A} analyzers are essentially exactly same hardware as an Agilent 16901A mainframe which is populated with {16912A, 16911A, 16910A} modules, except that in addition to the main 600W power supply, the 16901A has a second 175W power supply while the {16801A, 16802A, 16803A} have a second 15W power supply, and the 2-slot module interface board (MIB) of the 16901A is replaced by a 1-slot module interface board in the {16801A, 16802A, 16803A}. The module shroud also has a single slot opening.
As the hardware is essentially the same, they use the same logic analyzer application.
In theory, a {16804A, 16806A, 16821A, 16822A, 16823A} analyzer could be turned into a more flexible 16901A analyzer. More flexible in that a 16900-series mainframe supports older {16740/41/42A, 16750/51/52A, 16750/51/52B, 16753/54/55/56A} modules, which may be easier and/or less expensive to acquire.
In practice, I don't know if anyone has figured out how to do that yet, or at least I haven't seen anyone post here that they have. As far as I know, swapping a standard 16910A module into a 168xxA analyzer results in an unrecognized module, and swapping a 16803A/16823A 16910A module into a 16901A also results in an unrecognized module.
My guess is that there are some bits in the {16912A, 16911A, 16910A} module EEPROMs that indicate whether they are standard 16900-series modules, or 168xxA-series specific modules, and the logic analyzer application will reject modules that are swapped between the two series.
And probably some bits somewhere in the hardware that distinguish between a 16901A mainframe and a 168xxA analyzer. Maybe a tag somewhere in the motherboard BIOS? Or maybe somewhere in the MIB? A 168xxA analyzer needs to know the difference between a 1-slot MIB and a 2-slot MIB, maybe that would be a good place to store model specific information.

There is a "xmas gift" in this forum.
Gerald:
Successfully upgraded a 16804A from 250MHz sampling rate to 500MHz, but no way to upgrade the sample memory. Whatever option used (4Meg / 16Meg / 32Meg) it stays at the original 1Meg.
Any clues ?
