Installation
Installing the E5250A
5. Connect wires between BIASout1 and BIASin2, also between BIASout2 and
BIASin3.
6. Install the module into the slot 1 of the mainframe. For installing module, see
“To Install Plug-in Card” on page 2-8.
7. Connect BNC open caps to BIAS INPUT 52 and 53 connectors. So, the BIAS
INPUT 51 connector will be the BIAS input.
This example internally connects all BIAS INPUT connectors together. So, when
bias is applied to a BIAS INPUT connector, the bias will also be applied to all the
other BIAS INPUT connectors.
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.
To connect BIAS inputs externally.
You can use the BIAS INPUT connectors instead of the BIASin/out internal
connections shown above. See Figure 2-5. This example uses three BNC cables and
two BNC-T type (f-m-f) adapters. Recommended parts for the BNC-T type adapters
are listed below.
• Agilent part number 1250-0781: female(side)-male(center)-female(side)
• Agilent part number 1250-2405: male(side)-female(center)-female(side)
