Introduction	Additional options

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.
