Maximum number of data points per channel that can be acquired
The following table shows the maximum number of data points per channel that can be
acquired.
Data being Acquired
Display data only
Display data and event data
Event data only
Sampling length
The sampling length can be derived from the following equation.
Sampling length = the maximum number of data points per channel × sampling interval
Calculation example
• Display data only
Measurement channel : 2, computation channel : none
Data Maximum Number of Data Points and Sampling Length
Maximum number of data points = 1,200,000/(2 CH × 4 bytes + 0 × 8bytes) =
Display data
150,000. However, since 100,000 data points is the limit,
Maximum number of data points = 100,000
Display rate When set to 30 min/div (60 s sampling interval)
Sampling length = 100,000 data points × 60 s = 6,000,000 s (approx. 69 days)
Measurement channel : 12, computation channel : 6
Data Maximum Number of Data Points and Sampling Length
Maximum number of data points = 1,200,000/(12 CH × 4 bytes + 6 × 8 bytes) =
Display data
12,500
Display rate When set to 30 min/div (60 s sampling interval)
Sampling length = 12,500 data points × 60 s = 750,000 s (approx. 8 days)
• Event data only
Measurement channel : 2, computation channel : None
Data Maximum Number of Data Points and Sampling Length
Maximum number of data points = 1,200,000/(2 CH × 2 bytes + 0 × 4 bytes) =
Display data
300,000
However, since 120,000 data points is the limit,
Maximum number of data points = 120,000
When the event data sampling interval is 1 s
Sampling length = 120,000 data points × 1 s = 120,000 s (approx. 33 hours)
Measurement channel : 12, computation channel : 6
Data Maximum Number of Data Points and Sampling Length
Maximum number of data points = 1,200,000/(12 CH × 2 bytes + 6 × 4 bytes) =
Event data
25,000
When the event data sampling interval is 1 s
Sampling length = 25,000 data points × 1 s = 25,000 s (approx. 7 hours)
8.2 Function to Acquire Display Data and Event Data
Maximum Number of Data Points Per Channel
1,200,000 bytes/(number of measurement channels × 4 +
number of computation channels × 8)
Except, the maximum number of data points is 100,000
• Display data
900,000 bytes/(number of measurement channels × 4 +
number of computation channels × 8)
Except, the maximum number of data points is 75,000
• Event data
300,000 bytes/(number of measurement channels × 2 +
number of computation channels × 4)
Except, the maximum number of data points is 30,000
1,200,000 bytes/(number of measurement channels × 2 +
number of computation channels × 4)
Except, the maximum number of data points is 120,000
