Programming the Board

Since all of the MI, MC and MX boards from Spectrum are modular boards, they consist of one base board and one or two (only PCI and 
CompactPCI) piggy-back modules. This register SPC_PCIVERSION gives information about the revision of either the base board and the mo-
dules. Normally you do not need this information but if you have a support question, please provide the revision together with it.

If your board has a piggy-back expansion module mounted (MC und MI series boards only) you can get the hardwareversion with the follo-
wing register.

This register informs you about the production date, which is returned as one 32 bit longword. The upper word is holding the information 
about the year, while the lower byte informs about the month. The second byte (counting from below) is not used. If you only need to know 
the production year of your board you have to mask the value accordingly. Normally you do not need this information, but if you have a 
support question, please provide the revision within.

This register holds the information about the serial number of the board. This numer is unique and should always be sent together with a 
support question. Normally you use this information together with the register SPC_PCITYP to verify that multiple measurements are done with 
the exact same board.

This register gives you the maximum possible samplerate the board can run however. The information provided here does not consider any 
restrictions in the maximum speed caused by special channel settings. For detailed information about the correlation between the maximum 
samplerate and the number of activated chanels please refer th the according chapter.

This register returns the size of the installed on-board memory in bytes as a 32 bit integer value. If you want to know the ammount of samples 
you can store, you must regard the size of one sample of your Spectrum board. All 8 bit boards can store only sample per byte, while all 
other boards with 12, 14 and 16 bit use two bytes to store one sample. 

The following example is written for a „two bytes“ per sample board (12, 14 or 16 bit board).
