13. When you connect multiple driver boards and switches at a distance from the 87130A voltage drop limitations due to switch drive requirements switch quiescent current drive transistor drop cable resistance and LED current must be taken into account Agilent 24 volt switches are guaranteed to work with a minimum drive voltage of 20 volts The 87130A puts out a minimum of 22 5 V and the open drain DMOS output drivers of each channel on the driver board have a drop of 1 0 V Thus 1 5 V is left for the total voltage drop for the driver board cables and switch wires For example a seventh external driver board fully loaded with seven 87104A switches maximum 350 mA quiescent current plus 400 mA actuating current located at the end of the sequence of 70611 60010 Agilent 87130A Operating and Service Manual 2 11 Installing the 87130A Attenuator Switch Driver Connecting Switch Drivers to Switches and Attenuators 70611 60011 and 70612 60011 cables of 28 AWG wire size at a total cable length of 32 8 feet from the 87130A would have a voltage of 20 3 volts available at the driver board 21 5 V 750 mA X 0 065 ohms per foot X 32 8 feet X 0 75 This leaves 0 3 V that can be dropped in the wires from the board to the switches Thus if each switch has 400 mA actuating plus 50 mA quiescent current a combined length of 16 6 feet of 26 AWG wire would be the maximum length permissible to meet switch specifications 450 mA X
