Since version 3.0.11, if located in different CMWs, both master and slave SUU may
additionally run
. This allows to establish Hybrid Mode
with up to 2n cells on n CMWs.
Prerequisites
The minimum hardware and software configuration for hybrid mode using two SUUs
are:
●
Either
–
one R&S
CMW equipped with extra RF converter module (R&S CMW-B570B)
or
–
two R&S
CMWs and multibox sync equipment
and
●
One SUU with CDMA2000 extension (R&S CMW-B220A)
●
One SUU with 1xEV-DO extension (R&S CMW-B230A)
●
One option CDMA2000
®
1xRTT basic signaling (R&S CMW-KS800)
●
One option CDMA2000
®
1xEV-DO basic signaling (R&S CMW-KS880)
●
One option CDMA2000
®
hybrid mode (R&S CMW-KS888) per R&S
CMW
Limitations
All available functionality is supported in both signaling applications.
Setup Procedure
1. If using two R&S
CMWs, synchronize both R&S
CMWs according to the multibox
scenario.
2. Configure both FWAs on different RF converters (e.g. CDMA2000 Signaling on
RF1 COM and 1xEV-DO Signaling on RF3 COM)
3. Connect the DUT to the configured RF connectors using an external combiner.
4. Configure both signaling FWAs to the required RF frequencies and band classes.
5. Apply time settings as described in
As a result, CDMA2000 Signaling and 1xEV-DO Signaling should both be running
and the mobile should register in CDMA2000
®
1xRTT and open a session in
CDMA
®
1xEV-DO.
4.2.6 External Fading
An external fading scenario allows to route the forward link baseband signal to an
R&S
AMU200A that superimposes fading on the signal and routes it back. Thus fading
can be added to the forward link signal.
