Special Features | Spectrum

All Spectrum digitizers have a bandwidth that is limited to around half of the maximum sampling rate which is a good restriction when looking at the Nyquist-Shanning sampling theorem.

The BaseXIO option offers 8 asynchronous digital I/O lines on the base card. The direction can be selected by software in groups of four. Two of these lines can also be used as additional external trigger sources. This allows the building of complex trigger conjunctions with external gated triggers as well as AND/OR conjunction of multiple external trigger sources like, for example, the picture and row synchronisation of video signals. In addition one of the I/ O lines can be used as reference clock for the Timestamp counter.

This option acquires additional synchronous digital channels phasestable with the analog data. When this option is installed there are is a number of additional digital inputs available for every analog A/D channel. The digital data is stored in the upper bits of the data word. Using this option allows to acquire mixed mode data of analog and digital channels.

This option outputs additional synchronous digital channels phasestable with the analog data. When this option is installed there are 2 additional digital outputs for every analog D/A channel. The digital data is stored in the upper two bits of the 16 bit data word. If the option is not used or not installed, the upper two bits of the data word are not used for anything.
