Multiplexer Card Numbers
Agilent plug-in modules installed in an Agilent VXIbus mainframe are
treated as independent instruments each having a unique secondary GPIB
address. An instrument may be composed of a single plug-in module or
multiple plug-in modules. The card number identifies the module within a
switchbox or scanning voltmeter configuration. The multiplexer module
with the lowest logical address is always card number 01. The multiplexer
module with the next successive address is 02, and so on. Figure 2-1
illustrates the card numbers and logical addresses of typical single-module
switchboxes. Figure 2-2 illustrates the card numbers and logical addresses
of a typical multiple-module switchbox. Figure 2-3 illustrates the card
numbers and logical addresses of a typical multiple-module scanning voltmeter.
