If the 16500A power supply is dead an upgrade to a 16500C would replace everything except for the internal chassis frame, top, bottom, and side skin panels, the CRT, and the CPU board/power supply/module backplane. You can't just swap the CPU boards. In addition to replacing the 16500A CPU board with a 16500C CPU board, you also need to replace the front and rear panels, the front floppy drive and mounting bracket, the side fan/hard drive mounting bracket, and all of the internal ribbon cables. If you factor in the time it takes to strip all of the necessary parts out of a donor 16500C and then strip the parts out of the recipient 16500A and reassemble it with the 16500C transplant parts you would almost be better off paying the extra cost of shipping the entire 16500C. An exception might be when the shipping cost is crazy expensive. A few years ago I stripped the necessary upgrade parts out of a 16500C to ship to Alexandre in Brazil to upgrade a 16500A because in that case the shipping cost was crazy expensive. The 16500A or 16500B upgrade to 16500C kit was the E2497A. Here are the instructions for doing the A->C or B->C upgrade: /g/HP-Agilent-Keysight-equipment/files/16xx%2016xxx%20Logic%20Analyzers%20Accesories//E2497A-16500-Upgrade.pdf |
