6.4 GSM Module Test Dialog
The GSM module test comprises three functions: operation of the CTS as generator, burst analysis
using the CTS and IQ spectrum display. The module test and thus data transmission between CTS
and CTSgo start in generator mode. The left block in the dialog window indicates which of the ten
generator sets has been activated. A generator set includes the channel, the associated frequency
offset, and the output level of the generator. The set level applies to connector RF In/Out or RF Out 2
of the CTS, depending on the setting. This setting can be seen under the option Used RF connector.
The boxes of the block indicate whether the generator is switched on, whether the output signal
contains a bit modulation or whether a ramped or continuous signal is used. The midamble used is
indicated in another box of the window. To simplify the use of dual-band or triple-band mobiles, the
network definition and the RF attenuation value between mobile and measuring instrument CTS are
also part of the generator set. The network and the attenuation value of the current generator set can
be seen in the right block.
Important:
With bit modulation switched off, the displayed training sequence is of no importance. All other settings
are ineffective when the generator is switched off.
One of the ten generator sets can be selected using the buttons Generator 01 to „Generator 10“. The
CTSgo program will act differently depending on whether the Set only box is activated or not. With this
box activated, new generator settings are immediately active. When the box is empty, the user is
requested in a dialog to enter the desired generator settings. Terminating the dialog with OK sets the
entries.
