Sampling Rates
As described in more detail elsewhere in this manual, the SG-Link® OEM has four
sampling modes, being 1) Datalogging, 2) Streaming, 3) Low Duty Cycle and 4) High
Speed Streaming. Each of these modes supports a unique set of sampling rates. In
Datalogging and Low Duty Cycle modes, you may choose the sampling rate for the
session. In Streaming and High Speed Streaming, the sampling rate is a function of the
number of active channels being sampled and may not be set by the user.
Datalogging
The sampling rate may be set to any of the following rates:
•
32 samples per active channel per second
•
64 samples per active channel per second
•
128 samples per active channel per second
•
256 samples per active channel per second
•
512 samples per active channel per second
•
1024 samples per active channel per second
•
2048 samples per active channel per second
Streaming
The sampling rate is a function of the number of active channels:
•
If 1 channel is active, the sampling rate will be 736 samples per second for the
channel.
•
If 2 channels are active, the sampling rate will be 679 samples per active channel
per second.
•
If 3 channels are active, the sampling rate will be 617 samples per active channel
per second.
•
If 4 channels are active, the sampling rate will be 565 samples per active channel
per second.
Low Duty Cycle
The sampling rate may be set to any of the following rates:
•
500 samples per second for each active channel
•
250 samples per second for each active channel
•
100 samples per second for each active channel
•
50 samples per second for each active channel
•
25 samples per second for each active channel
•
10 samples per second for each active channel
•
5 samples per second for each active channel
•
2 samples per second for each active channel
•
1 sample per second for each active channel
•
1 sample every 2 seconds for each active channel
•
1 sample every 5 seconds for each active channel
•
1 sample every 10 seconds for each active channel
