Operating Modes
Configuration
The board provides 64 filtered (10kHz nominal cut-off) differential inputs for four IP-ADC-8411 boards mounted on an 8004 Carrier Board
Links
Links allow the isolated analogue grounds of each group to be connected to digital (VME) ground.
Excitation
Four 8912 DC-DC converter options supply +/-12V to each front panel connector.
