Hello Mark, At the moment it would seem the Burst problem is healed, but it might be interesting to see how this would play out (Page 10.6-7) I was also hoping you might help me go through this, so I can get a working knowledge of my (HP 5005A Signature Multimeter) while verifying the work is done. My son bought me this piece of test gear, I have never used it, I have the manual and the basic bootup and functions all seem to be ok with no errors.
I believe the Error light is working as intended. leaving the intermittent BER light I am going to attempt to find what's up with that, it's off more than its on, and looking at U20 as on Pg. 10.6-7 with the Address decoder and my Rigol 16 channel Logic Probe on my scope would go a long way in my understanding of how to use this equipment and the confidence to use it in the future. I realize this is unnecessary, look at how far you got with a voltmeter! I really want the understanding you have, to be able to look at a circuit understand how it's supposed to work, like understanding ECL logic and knowing what the inputs should be and what to expect at the outputs and where to look if it's wrong.
You have been great at explaining things to me, very easy to understand and pointing me at the right literature to supplement that. Please note, your time is not wasted on me.
