Explanation
When Bandwidth (bandwidth limit) is not set to Full, high-resolution data exceeding 8 bits
can be handled because noise included in the data is reduced through filtering.
Ordinarily, data is saved in the acquisition memory as 8-bit data, so the resolution of
high-resolution data that exceeds 8 bits is reduced to 8 bits and then saved. By turning
ON the high-resolution mode, you can save this data as 16-bit data. This means that you
can save high-resolution data exceeding 8 bits in a high-resolution format.
When the high-resolution mode is ON, the record length is halved. (For the DL1620/
DL1640, 8 Mwords → 4 Mwords; for the DL1640L, 32 Mwords → 16 Mwords.)
