●
Measurement period
= time from the beginning until the end of a step at one
frequency point
●
n
= number of frequency points in the list
●
X
= actual time for a single measurement, calculated according to the formula:
X = 2 * AverageCount * (Apertu 100µs)
●
AverageCount
= number of averaged measurement readings
●
ApertureTime
= width of the sampling window
Aspects to consider
●
Minimum measurement time
220
µ
s
The time span of the measurement pulse must not be below the mini-
mum value, derived from:
AverageCount (min) =
1, ApertureTime (min) =
10
µ
s:
X = 2 * 1 * (10
µ
s+100
µ
s) = 220
µ
s
Shorter pulses cannot be measured.
●
The total number of pulses is summed up of the number of frequency
points and the start burst.
