Measuring the Signal-to-Noise Ratio of Burst Signals

When TDMA transmission methods are used, the signal-to-noise ratio or the
deactivation dynamic range can be measured by comparing the power values
during the activation phase and the deactivation phase of the transmission burst.
For this purpose, the R&S

 

FSVA/FSV provides the function for measuring abso-

lute and relative power in zero span. In the following example, the measurement
is performed using a GSM burst.
