This logic is explained in more detail below :
1) When acquiring display data only
If we assume that the number of measuring channels is
20, the number of computing channels is 10, and the
display rate is 30 min/div (60 sec sampling interval),
then :
Number of data per channel = 1,200,000 bytes/(20
×
4
bytes + 10
×
8 bytes) = 7,500 data
*
* Maximum number of data points is 100,000.
Sampling length per file = 7,500
×
60 sec = 450,000 sec
= approx. 5 days
2) When acquiring event data only
If we assume that the number of measuring channels is
20, the number of computing channels is 10, and the
sampling interval is 1 sec, then :
Number of data per channel = 1,200,000 bytes/(20
×
2
bytes + 10
×
4 bytes) = 15,000 data
*
* Maximum number of data points is 120,000.
Sampling length = 15,000
×
1 sec = 15,000 sec =
approx. 4 hours
3) When acquiring both display data and event data
The sampling length is calculated by defining the
capacity for display data as 900,000 bytes and the
capacity for event data as 300,000 bytes. The method
of calculation is the same as shown above.
Except, the maximum number of data points is 75,000
for display data and 30,000 for event data.
