Can anyone provide me a maintenace manual of the Wiltron 67xxA sweeper.
I can scan it. My unit gives signal and the unlock led is flashing.
Hello,
No luck, I don't get the manual, but I have got this prob already.
to help you, two ways:
==> Does this led blinking on analog sweep mod ? if yes, that is normal
==> Does this led blinking on digital sweep mod ? if yes, that is not normal
==> Does this led blinking on CW mode ? if yes, that is not normal
==> Does this prob appears over all the bands (10- to 2 Ghz, 2 to 8, 8 to 12,4 and 12,4 to 20 Ghz ) ?
If it appears only on one band or two bands : perhaps you have to calibrate it: for that, You need a Ghz counter (EIP or other) and using mix Keys (shift + trigger key + number): if you want, I can give you the correct numbers.
==> if the prob appears over all bands: for me, it is a hardware prob.
That I have got on two 6759A : The A6 were defective (on the twice) and the A3 board (one time)
---> more probably the A6 boards if defective (COARSE LOOP) and drives the VCO Board (A3)
---> after, it is possible that is the A3 boards is defective ( VCO), and after other boards.
I have seen the manual on Ebay, but he does not sell outside of America :-(, and I can't get it...
You can looking-for "Wiltron 6737A 6737A-20 Maintenance Manual" on Ebay
