Data Memory Size
With 15 GB of flash memory available for data storage, the SLICE6 DAS can record
~52 minutes of data at the maximum sampling rate (6 channels at 400 ksps). Since the
recording capacity is very large, it is generally best to limit sampling rates and event durations
to the minimum necessary to avoid large and cumbersome data files. Large files take longer
to download and may also be time-consuming to post-process or difficult to share. Use of
the Region of Interest (ROI) download can save a great deal of time if implemented properly.
Sampling Rates
User-selectable sampling rates are available from 2,000 sps to 400,000 sps.

Maximum Sampling Rate
(per channel)
6 400,000 samples per second (sps)
* All channels are recorded even if they are not programmed.
With 15 GB available for data storage, there are 7,500 M samples available (1 sample =
2 bytes). To determine the maximum recording time, divide the number of samples by the
product of the sampling rate and the number of channels.
7,500,000,000
= # of seconds
Sampling rate (sps) X # of channels
Example: 6 channels of data at 400,000 sps
7,500,000,000
= 3,125 sec (52 minutes)
400,000 X 6
Circular Buffer Limitations
Due to the nature of flash memory, the system cannot be armed in Circular Buffer mode
indefinitely. To determine the maximum time available, use the equation below:
0.8

recording time = maximum time available in Circular Buffer mode
Example:
0.8

3,125 sec = 2500 sec (41 minutes)
In this example, the test must occur within 41 minutes, after which time the unit stops
recording data.
