Just a quick update; I took apart the front panel module for the 8569A Someone repaired the switch rotor with epoxy, I'll post pictures later on, I have to get the day started and will have pictures up later today or tomorrow. EDIT; Here is a picture of the glue job that was done on this rotor. I think I can make this work........ This is good news. I have some fresh JB Weld and my trusty hair drier.... For the time being I am going to get one good front panel assembled for my partner in this project and get him a working analyzer. I should be able to make one good front panel from the remaining parts. Sometimes I like Mondays :-+ :-+ |

Use a little silicon oil or Vaseline on the tap. You want it to cut and not stick. Depending on what is on the other side, it might be easier to just drill thru and use a bolt and nut instead of small screws. |

I know some of those systems are not that precise, but couldn't a laser 3D printer make a new part (if the file could be created) with new posts for the contacts? I don't know ... :-// |

I got an Agilent E4411B Spectrum Analyzer last year - great unit. It's B&W, but it actually can display colors if you go into the right menu and change all the assignments for traces and this and that different colors. Takes a while. 'Cept the problem is it won't store all those colors and next time you turn it on - it's back to B&W. I looked at what it would take to make it remember the colors. It takes a firmware upgrade - but to do that you have to get the software from Keysight, and then before that, you must upgrade the memory, and to do that would cost somewhere between $1k and $2k. All to make it display colors. The thing didn't even cost me that much. Grrrr. |
