Measuring the Signal-to-Noise Ratio of Burst Signals
When TDMA transmission methods are used, the signal-to-noise ratio or the deactiva-
tion dynamic range can be measured by comparing the power values during the activa-
tion phase and the deactivation phase of the transmission burst. For this purpose, the
R&S
ESR provides the function for measuring absolute and relative power in zero
span. In the following example, the measurement is performed using a GSM burst.
