7.6 Changing OMI
totrms
(AGC on modes only)
The picture below shows, how to adjust the RF OMI total rms, in order to optimize the
transmission performance in terms of CNR, CSO, CTB and BER. For details, please refer to 5.3.
Fig. 7.6.1: Setting RF OMI
totrms
of ES10/ES26
With software release 2.0, the RF OMI
totrms
(OMIrms in the figure beyond) is shown in %. In
previous software releases, RF OMI
totrms
was shown relative (in dB) to a nominal value.
The display in % enables an easy comparison e.g. with the graphs as shown in 5.3. For that
reason, ES10 application software release 1.12 and later supports this feature.
Notes:
1. OMI nominal refers to a factory setting and cannot be changed by the user.
2. RF-OMI
totrms
setting is only relevant in AGC-on mode.
3. The setting range for RF-OMI
totrms
might change slightly from device to device due to
production tolerances.
