Additional options
Digital inputs
This option allows the user to acquire additional digital channels synchronous and
phase-stable along with the analog data.
Therefore the analog data is filled up with the digital bits up to 16 Bit data width. This
leads to a possibility of acquiring 4 additional digital bits per channel with 12 bit res-
olution boards, and 2 additional digital bits per channel with 14 bit resolution boards.
The connectors for these digital inputs are mounted on an additional bracket. The fig-
ures show the option on boards with either one or two modules.
Extra I/O (Option -XMF)
With this simple-to-use enhancement it is possible to control a wide range of external
instruments or other equipment. Therefore you have 24 digital I/O and the 4 analog
outputs available.
The extra I/O option is useful if an external amplifier should be controlled, any kind
of signal source must be programmed, an antenna must be adjusted, a status informa-
tion from external machine has to be obtained or different test signals have to be rout-
ed to the board.
The additional inputs and outputs are mounted on an extra bracket. The figure shows
the allocation of the two connectors. The shown option is mounted exemplarily on a
board with two modules. Of course you can also combine this option as well with a
board that is equipped with only one module.
It is not possible to use this option together with the star hub or times-
tamp option, because there is just space for one piggyback module on
the on-board expansion slot.
