16 Agilent 34980A Mainframe User’s Guide
1 Introduction to the 34980A
The Digital Modules
The 34950A and 34952A digital modules add two additional measurement
input capabilities to the system: digital input and event totalize. For more
information, see the individual User's Guides included with those
modules.
Digital Input
The digital modules have multiple non- isolated 8- bit input/output ports
which you can use for reading digital patterns. You can read the live
status of the bits on the port or you can configure a scan to include a
digital read. Each port has a separate channel number on the module
and contains 8- bits. You can combine ports to read 16- or 32- bit words.
