7.4 Configuration Menu in the GSM Module Test
7.4.1 Attenuation
In the module test, this dialog permits to standardize the attenuation values of the parameter sets in
generator, burst analysis and IQ spectrum mode. After entering the input attenuation and output
attenuation, close the dialog window by clicking on OK. In another dialog window, you will be prompted
whether you really want to overwrite all parameter sets with these values. Click on Yes if you are really
sure about it, otherwise select No.
7.4.2 Generator Settings
The Configurations menu includes the Generator Settings submenu, where the menu items “RF
Generator 1” to “RF Generator 10” can be found. Select one of these commands in order to edit the
desired generator parameter set.
The CTS provides an RF signal. The parameters of this RF signal are set in this dialog window. In the
first field, the transmission channel of the CTS is entered, in the second the frequency offset to the
fixed GSM frequency grid of 200 kHz. The CTS output power can be set in the third field. This power is
present at the selected RF connector “RF In/Out“ or “RF Out 2“. A click on “Generator on“ decides
whether the RF generator sends the set signal or not. With “Bitmodulation on” you can decide whether
a midamble is included in the signal or not. In the fourth field, the training sequence (TSC) of the
midamble is defined. With “Ramp on” you can decide whether the RF signal is with or without a burst.
