Carrier frequency configuration example
The following example shows a typical configuration for a burst carrier frequency
measurement. In the example, the gate delay and gate time are set manually. If
the characteristics of the pulse are unknown, the “on time” can be measured
separately to insure that the delay and time are set within the threshold detector’s
sensitivity range (see Chapter 3 for more pulse measurement examples).
