bandwidth limiting capability, such as
the SC-8 Signal Conditioning unit.
Ch Info. By pressing
, you can access data on the analog cards that have passed
QC. For example:
1LoPass Notch+60,3-5,9 S/N 67Passed
2LoPass Notch+60,3-5,9 S/N 127Passed
3LoPass Notch+60,3-5,9 S/N 256Passed
Here LoPass indicates the input amplifier configuration, the powerline notch filter is a
60/180/300/540 Hz filter, (the + indicates a modification level), and the three board
serial numbers are 67, 127, and 256.
Note that a number (0097) is visible before the program designator (AMT 0538). This
number is the label of the last data block written to the data cache. The next time a block of
data is written to the cache, it will be numbered 0098.
