Installation
Installing the E5250A
96-output multiplexer (1-BIAS input, 1-IV input, 4 modules)
To make this multiplexer, you need four E5255As, eight wires (furnished), five
BNC open caps (furnished), and three BNC cables. The example uses the SMU
INPUT 1 connector as the IV input, and uses 0 Ω resistors.
1. See "24-output multiplexer (1-BIAS input, 1-IV input, 1 module)" and make
four 24-output multiplexers. Then the IVin1 cable on all modules must be
connected to the SMU1 input connector.
2. Install the modules into the mainframe. For installing module, see "To Install
Plug-in Card" on page 2-8.
3. Connect BNC open caps to the BIAS INPUT 51 connector of the module in the
slot 1 and all BIAS INPUT 52 connectors.
4. Connect BNC cables between the following connectors:
• BIAS INPUT 51 (slot 4) and BIAS INPUT 53 (slot 3)
• BIAS INPUT 51 (slot 3) and BIAS INPUT 53 (slot 2)
• BIAS INPUT 51 (slot 2) and BIAS INPUT 53 (slot 1)
So, the BIAS INPUT 53 connector of the module in the slot 4 will be the BIAS
input.
96-output multiplexer (1-BIAS input, 1-IV input, 4 modules)
Do not forget to connect the BNC open caps to the unused BIAS INPUT connectors.
Otherwise, you will be shocked if you touch the connectors while bias is applied.
DO NOT connect the BNC short cap to the connectors. If you do, the E5255A and
the Bias Source will be destroyed when the bias is applied.
