Hi I have the original CLIP manual for 8753D and I have done a PDF and uploaded at ? To download ? ? Regards Yves De?: [email protected] <[email protected]> De la part de Colby Burkett

Objet?: Re: [HP-Agilent-Keysight-equipment] I'm officially lost now with this 8753ES ? It's available on eBay listed as 8753D CLIP. I bought mine that way. Artek doesn't seem to have it. Not sure if the eBay seller is licensed to sell it or not, but it's been years since I bought, and it's still listed by the same seller. ?

have changed.? What is the part number for A11 in the 8753D?? In my ES it is
08753-60162.
What I'm seeing is that the YTO is over 200 MHz too high on the lower
frequencies (under say 1-1.5 GHz) so the test 48, generate proper pretune
voltages, fails.? The output at P1-1 to P1-2 is somewhat higher at the low end
than the manual shows, being 4.0 volts in mine vs. 3.5 volts stated in the
manual.? U18-6 voltages (not shown on the schematic shown below), out of the
DAC, look good.? The drive signal from A11 is current rather than voltage so a
slight difference could be attributed to tolerance of my YTO coil resistance
(45.2 vs. 44.4 ohms?? Not enough for that difference).? I also tried swapping
the YTO for another and the replacement behaved exactly the same.
The instrument PLL locks nicely when using an external source.
Where did you find the CLIP you sent?? I'd like to see the rest of the A11
board, and maybe more, as it may be closer than the A/B CLIP I have.? And I'd
*love* to see a CLIP for the A3 source PCB!
