When you specify the number of periods, you determine the number of peri-
ods of the input signal during which the measurement is to be performed.
You can specify the number of periods for each channel separately.
Table 6-2
Setting of the number of periods
Variable:
Number of Periods
PeriodNumber_Chan_1
PeriodNumber_Chan_2
PeriodNumber_Chan_3
PeriodNumber_Chan_4
PeriodNumber_Chan_5
PeriodNumber_Chan_6
PeriodNumber_Chan_7
PeriodNumber_Chan_8
By selecting the measuring range, you can also increase the period duration
which is measured.
The parameterized measuring range applies to all channels.
