AF/RF Connectors (Connection Control – AF/RF)
The AF/RF tab (function group GSM400/850/900/1800/1900-MS , Non Signalling mode) configures
the connectors for RF signals. This includes the setting of
•
The RF input and output of the CMU (RF Output, RF Input)
•
An external attenuation at the connectors (Ext. Att. Output, Ext. Att. Input)
The tab also controls the wideband peak power measurement (Wideband Power) and indicates the
result. The name and function of the AF connectors is indicated in addition.

The Wideband Power measurement is explained in section Softkey-Oriented Version on p. 4.69 ff.
AF Connector
Overview The AF Connector Overview shows the destination of the input signals fed in via
AF IN and AUX 1 and the signal sources for the two audio output connectors AF
OUT and AUX 2. In contrast to the
Signalling test mode (see section AF/RF
Connectors on p. 4.179 ff.), the routing of input and output signals is fixed: The
connectors AF IN and AF OUT are used as input and output for the primary audio
circuit (Analyzer 1, Generator 1). AUX 1 and AUX 2 are used as input and output
for the secondary audio circuit (Analyzer 2, Generator 2).
Audio measurements on the CMU can be performed with option CMU-B41, Audio
Generator and Analyzer. For more information refer to section Audio
Measurements on p. 4.68 ff. and to the CMU 200/300 operating manual.
