Title: Diagram needed HP8753A CRT assy boards Post by: PM3295 on December 11, 2011, 05:50:13 17:50 I have this network analyzer which developed a problem with the vertical drive to the CRT.
The problem seems to be on the X-Y drive board (A18) mounted on the CRT assembly. The service manuals for the instrument are available on the net, but all of them lack the diagrams for the A18 board. The manual refer to adjustments on this board but strangely provides no circuit diagrams. I am not sure if this even exists. Sometime they use another manufacturer for the CRT module in their equipment, but this board seems to be from HP themselves. I searched on the Agilent yahoo groups as well but no luck thus far. |
