Initialization Programming the Board

Hardware version

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.

Date of production

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.

Serial number

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.

Maximum possible sample rate

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.

Installed memory

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).

SPC_PCIVERSION 2010 r Board revision: bit 15..8 show revision of the base card, bit 7..0 the revision of the modules

SPC_PCIEXTVERSION 2011 r Board’s expansion module hardware revision as integer value.

SPC_PCIDATE 2020 r Production date: year in bit 31..16, month in bit 7..0, bit 15..8 are not used

SPC_PCISERIALNO 2030 r Serial number of the board

SPC_PCISAMPLERATE 2100 r Maximum samplerate in Hz as a 32 bit integer value

SPC_PCIMEMSIZE 2110 r Instaleld memory in bytes as a 32 bit integer value

SpcGetParam (hDrv, SPC_PCIMEMSIZE, &lInstMemsize);

printf ("Memory on board: %ld MBytes (%ld MSamples)\n", lInstMemsize /1024 / 1024, lInstMemsize /1024 / 1024 /2);
