We're running through the calibration on our 067-0587-10 Standardizers and they're failing frequency response. All points lead to the
067-0655-00 fixture going bad, which we only have one of. We tried to substitute the 067-0589-00 fixture in place of it and pull the + & - signals off of it, but the frequency response was even worse, on the order of -12% at points. What is the main difference between the 067-0655-00 and the 067-0589-00? The 0655 looks like they've spent significant effort shielding the pickoff points, and the 0589 has a little more unshielded coax showing. However, the flexible extender board has a similar amount of unshielded coax to the 0589 and seems to pass the signals just fine. Is it just the rolloff of the coax used in the 0589?Are there any engineers out there that worked on the 7000's still around?
Thanks for any help,
Steve
