Hybrid Mode on a Single SUU
In this mode, the signaling firmware applications CDMA2000 and 1xEV-DO run in par-
allel on the same SUU (in particular they run on the same R&S
CMW).
Prerequisites
The following minimum hardware and software configuration for hybrid mode with a
single SUU is required:
●
Extra RF Converter Module R&S CMW-B570B
●
SUU module (R&S CMW-B200A) equipped with
–
CDMA2000 signaling extension module (R&S CMW-B220A) and
–
1xEV-DO signaling extension module (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)
Limitations
All available functionality is supported in CDMA signaling application.
In hybrid mode on a single SUU, 1xEV-DO signaling only supports Rev. 0/A. If Rev. B
is required to run in hybrid mode, the dual SUU setup has to be chosen.
Setup Procedure in Hybrid Mode
1. Select scenario hybrid mode in both CDMA2000 and 1xEV-DO.
2. Configure both FWAs on different RF converters (e.g. CDMA2000 Sig on RF1
COM and 1xEV-DO Sig 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. Switch both CDMA2000 sig and 1xEV-DO sig on in any order.
As a result, CDMA2000 sig and 1xEV-DO sig should both be running and the
mobile should register in CDMA2000

1xEV-DO.
4.2.5.4
Hybrid Mode on Two (or more) SUU
Hybrid mode using two SUUs is preferable in the following cases:
●
1xEV-DO Rev. B is required
●
One instrument doesn't offer a sufficient amount of RF paths, so the hybrid mode
has to be setup using two R&S
CMWs in a multibox scenario
