Anritsu/Wiltron 68369A signal generator - FW update possible?
« on: October 06, 2022, 10:55:07 pm »
Hi all,

I am looking into seeing if there is any way to update the FW on these older Wiltron designed/Anritsu branded signal generators. The specific unit I would like to update is an 68369A, but there are many models in this series that also run the same computer.

I found a service manual that makes mention of different FW revisions, but there is nothing on how to perform updates. I do not see any FW files floating around online as well.

If anyone has some insight into these units I would appreciate it.

Thank you,
Kevin

lil bump

Also posted the same question an anritsu-wiltron groups io: https://groups.io/g/anritsu-wiltron/topic/94171676#472

One person indicated that FW is stored on an internal rom. Looks like the unit needs to be opened and this rom accessed to do FW stuff.

Does anyone have one of these and possibly poked around in the past? Even just general pics of CPU board would be useful.

It was an easy process. The FW chip is socketed and it used an ultraviolet programmer. It will be difficult to get the FW files and figure it out though.

Also just noticed. Is that photo of your unit? That is a 68369A/NV and there would not be a FW update as it's specific to the Navy.
