Re: 8702A service manual [SEC=UNOFFICIAL]
|
Found the service manual for the 8753, thanks ,didn't see anything regarding the video, will delve deeper into it today. One of the 8702's has arcing in the eht but haven't taken
the covers off yet. The other seems to be working fine, but with old age( mine), the display is getting harder to read.
IS there any advantage I over the 8702 n installing the 8753 firmware as I am only doing RF work, not optical. I have 3 different S parameter test sets, including 1 x 75 ohm model(
still in storage so can't remember the model number).

I believe the 8702A is an 8753C with different firmware (display is color).? Find the video, pick it off and feed it into a Gonbes video converter (or similar) from eBay.? You may need to add an LM1881 sync seperator
depending on which scan converter you choose.
I don¡¯t know of a dedicated service manual for the 8702A. These units are essentially a 8753A with modified firmware for fibre testing with the additional light bridge. ?
There are 8753A service manuals online.?
After having a search, it appears that connecting a external monitor won¡¯t be easy. You may have to use something like a Simmconn Lab LCD conversion to get external monitor capabilities.
