Gathering information from the card Programming the Board
.
Hardware version
Since all of the boards from Spectrum are modular boards, they consist of one base board and one or two piggy-back front-end modules and
eventually of an extension module like the star-hub. Each of these three kinds of hardware has its own version register. 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 additional piggy-back extension module mounted you can get the hardware version with the following register.
Production date
This register informs you about the production date, which is returned as one 32 bit long word. The upper word is holding the information
about the year, while the lower byte informs about the week of the year.
The following example shows how to read out a date and how to interpret the value:
Last calibration date (analog cards only)
This register informs you about the date of the last factory calibration. When receiving a new card this date is similar to the delivery date
when the production calibration is done. When returning the card to calibration this information is updated. This date is not updated when
just doing an on-board calibration by the user. The date is returned as one 32 bit long word. The upper word is holding the information about
the year, while the lower byte informs about the week of the year.
Serial number
This register holds the information about the serial number of the board. This number 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.
