Ts and Tm at point 1
Between point 2 (previous conditions) and point 1, the test signal changes in frequency
from 800 MHz to 100 MHz but does not change in level. Thus, Ts is determined as
follows:
Ts = 2 × (0.8E9 - 0.1E9) / 1E9 = 1.4 ms
The averaging factor is 2 for the point. This determines Tm as follows:
Tm = 6.9 + 3.9 = 10.8 ms
•
Ts and Tm at point 2
Between point 1 and point 2, the test signal changes in frequency from 100 MHz to 800
MHz but does not change in level. Thus, Ts is determined as follows:
Ts = 1 × (0.8E9 - 0.1E9) / 1E9 = 0.7 ms
The averaging factor is 1 for the point. This determines Tm as follows:
Tm = 6.9 ms
Thus, the measurement time is determined as follows:
Ts (at point 1) + Tt + Tp + Tr + Tm (at point 1) + Ts (at point 2) + Tp + Tm (at point 2) =
1.4 + 2.0 + 1.0 + 2.0+ 10.8 + 0.7 + 1.0 + 6.9 = 25.8 ms
