Did so with some expensive DACs and HV amps, over $3K in just two part types!! But they are here in my hands  :phew:

'Just in time' has always been horse-crap.  The manufacturer where I had my first full-time job decided to save money by moving to producing exact component counts and JIT supply chains.  No order could ever be completed on time, and some were cancelled due to failure to meet contract.  So they ended up warehousing expensive finished product until they could find a buyer.

You always have a reject / failure rate, and letting a sales dweeb order your manufacturing supply instead of a production engineer is never going to work smoothly.  Particularly when they find a cheaper supplier, and order a load of counterfeit components.

mawyatt:
Agree, always thought JIT was a recipe for disaster, so many opportunities for a kink in a single component delivery to stop the entire product production. Unless you build up an inventory of all components to allow for a issue with JIT you are at risk, then why bother with JIT if you maintain a backup inventory!!!

This is a developmental control system to support a new technology for Phased Array Systems, hopefully leading to a full custom chip design. So not exactly a case for JIT, but the shortage is very real and causing lots of issues. This has caused the design approach to shift from using the best design & components for the purpose, to designing for a generic solution which just mets the needs and uses generic components, or worse having to alter the requirements to met the available components.....not exactly the best design approach IMO :o

Best,

Note this is completely untested! I wouldn't try it without tv84 verifying it first.

Thanks, I'll wait for verification since I don't understand how this firmware works. I've already messed things up enough :P

Best,

The file is correct.  :-+

For future reference, both files are attached. As blurpy said, untested.

Just did the downgrade to the X-E from the X version and the CC offset remains. Tried a couple cal routines all unsuccessful in removing the offset. So will just have to live with this unit having a CC offset of 100ma for now I guess.

Thanks for the help.

Edit: Forgot to mention that both files work and allow transitioning from X-E to X and from X to X-E versions for the 07R2 firmware.

Best,
