Please help I want to find the connection point between the mainboard and the dc-dc red wire in 4 pin connector. Which device on the mainboard (in the red circle in the first picture) does it connect to and what is the voltage? Where does it connect to? I can't see the circuit in the middle layer. (Left side in last picture ) where connect to component Thank you for help |

Here's the pinout from my 4263B: Left to right (viewed from front of instrument) - Red, Black, Yellow, Black. Voltages: Red - 2.68V (DC Bias supply?) Black - GND Yellow - 16.0VDC Black - GND (GND pins are connected together) Also, check out my unlock program if you want to activate options 001 and 002 if not already activated on your instrument. :) https://github.com/JaredCabot/HP-Agilent-4263B-Option-Unlocker |
