I have no experience with this type of display that is used in the 3458A. I am not sure exactly what the technology is called. You used the term "VFD", so what does that mean? Agilent/HP CLIP calls the display an "IC Display - FIP". I am not sure what the "FIP" means. The original display I took out was made by Noritake. It is obviously a custom display for HP. There is a DC/DC converter to power the display and it is obvious that this is supplying a higher voltage to the IC, maybe 50 volts or so. There are two caps on the high voltage supply lines that are 47 ufd/63v.
