HP E1418A - Manual (Page 18)

As shown, there are four major assemblies that make up an HP E1418A:
– Channels 1 through 8 main board and VXIbus backplane circuitry.
– Channels 9 through 16 expansion board.
– Isolated or Non-isolated plug-on modules.
– Terminal Module.
Channels 1–8 main board and VXIbus backplane circuitry.
This assembly contains all the VXIbus interface and decoding circuitry.
Isolated and Non-Isolated plug-on modules for channels 1–8 connect to this
assembly. The panel connectors for the terminal module are also mounted
on this assembly.
The optional Channels 9–16 expansion board is electrically connected and
mechanically mounted to the main board. Isolated and Non-Isolated
plug-on modules for channels 9–16 connect to this assembly.
Isolated or Non-isolated plug-on modules are required for every channel.
Eight plug-on modules mount to the main board and 8 plug-on modules
mount to the expansion board. Any combination of isolated or non-isolated
plug-on modules may be used, but every channel must have a plug-on
module installed.
The Terminal Module shown in Figure 1-2 is the standard screw-type
terminal module. This module provides screw connections for each channel
output, the calibration connections, and the external trigger in connections.
This module also contains two jumpers for each channel; one, called the P/J
Jumper, to enable or disable VXIbus programming of the channel mode
(either voltage or current) and one, called the V/I Jumper, to set the channel
mode when the P/J Jumper is in the Jumper position.
