Channel Measurements
Making Channel Measurements
Procedure for System
The following is an outline for measuring system flatness using two points in
Flatness Measurement
the system. For example, a reference trace could be taken at the
headend,
then compared to a flatness measurement made somewhere out in the
system.
1. Take a reference trace at point A as previously described (for example, at
the
headend
or first trunk ampliEer).
2. Go to point B and make a measurement. The result is the difference
between points A and B.
3.
Use the FAST SWEEP function for real-tune amplifier adjustments.
4.
Use the SLOW SWEEP for the most accurate results when scrambled
channels are present.
