5.10.7 Maximum Time of Performance Measurement
(1) Maximum measurement time
The timer used for performance measurement is comprised of a 40-bit counter.
The maximum measurement time varies with selected unit of measurement.
To select the unit of measurement, use the Time unit list box of the Performance Analysis Conditions dialog box.
The maximum measurable times for the respective units are listed in the table below.
Table 5.26 Maximum measurable times
Resolution
Maximum measurable time
10 ns
Approx. 3 hours, 03 minutes, 15 seconds
20 ns
Approx. 6 hours, 06 minutes, 30 seconds
40 ns
Approx. 12 hours, 13 minutes, 00 seconds
80 ns
Approx. 24 hours, 26 minutes, 00 seconds
160 ns
Approx. 48 hours, 52 minutes, 01 seconds
1.6 μs
Approx. 488 hours, 40 minutes, 18 seconds
CAUTION
Note that results of performance measurement carry an error equal to ±1 times the resolution (e.g. ±20 ns when the resolution
is 20 ns).
(2) Maximum measured number of passes
Numbers of passes through sections are measured by a 32-bit counter. Measuring up to 4,294,967,295 passes is thus possible.
