8. EXPLANATION AND APPLICATION OF
MEASUREMENTS
8.1 Introduction
This section gives the theory behind the measurements whose
operating instructions are described in Section 7. The meaning of the
measurements and how they are used is discussed. This section is
divided into the following paragraphs:
8.2 Units of Measurement
8.3 Level (Gain or Loss) and Frequency
8.4 Idle Channel Noise
8.5 Notched Noise (Noise with Tone)
8.6 Signal-to-Noise
8.7 PAR
8.8 Gain Slope
8.9 Idle Channel Impulse Noise
8.10 Phase Jitter
8.11 Amplitude Jitter
8.12 Notched Impulse Noise
8.13 Phase Hits
8.14 Gain Hits
8.15 Dropouts
8.2 Units of Measurement
As with any system of measurement, standard units of measurement
have been established in transmission testing to enable you to
meaningfully evaluate measurements and make comparisons of the
results
This paragraph discusses units of measurement used in analog
transmission
level and noise measurements. Refer to Figure 8-1.
