Achieving Stable Results with GSM Signals
Signals with a pulse repetition frequency (PRF) close to a multiple or a
submultiple of the 440 Hz chopper-amplifier signal generate a beat note at a
frequency between the PRF and 4F400Hz0 Hz. Control over the filter settings is
again required to obtain stable results.

The PRF of a GSM signal is approximately 217 Hz and thus requires
more averaging than most other TDMA signals. To achieve a stable
measurement use the filter setting procedures to set the
