To Modify BIAS Input

Each multiplexer block has an independent BIAS input. You can change the BIAS

input internally using the BIASin/BIASout terminals shown in Figure 2-2, or

externally using the BIAS INPUT connectors. For actual examples of modifications,

see “E5255A Configuration Examples”.

To Use Multiplexer Blocks on another E5255A

When a module is installed in a mainframe slot, six module pins are connected to

the mainframe internal bus. So, if multiplexers on different E5255As use the same

module pin, the IV inputs are connected together via the internal bus.
