●
Standard Cell
:
Standard WCDMA cell with only one RF output path.
●
Dual Carrier
:
WCDMA cell supporting dual carrier HSDPA in the downlink with restrictions for
one frequency band. Multi-band support can be enabled by the parameter "DB DC
HSDPA", see
Carrier 1 and carrier 2 use different output paths. Many parameters can be config-
ured individually per carrier.
Option R&S CMW-KS404 is required.
Option R&S CMW-KS404 is required for dual band dual carrier HSDPA.
●
Standard Cell Fading / Dual Carrier Fading
:
"Standard Cell" or "Dual Carrier" plus fading and/or AWGN insertion.
Either external fading via a connected R&S AMU200A or internal fading via an
internal fader I/Q board.
Option R&S CMW-KS410 is required, for internal fading also R&S CMW-KE100
and R&S CMW-KE400, for "Dual Carrier Fading" also R&S CMW-KS404.

Standard Cell RX Diversity Fading / Dual Carrier RX Diversity Fading
:
"Standard Cell Fading" or "Dual Carrier Fading" with RX diversity.
Either external fading via a connected R&S AMU200A or internal fading via an
internal fader I/Q board.
Enable it if you use a fader to shift the frequency of the carrier for RX diversity
tests.
If the parameter is enabled, the second carrier in dual carrier scenario uses the
center frequency of the first carrier and both use first TX output path while the sec-
ond TX output path is used by fading signal.
Option R&S CMW-KS410 is required, for internal fading also R&S CMW-KE100
and R&S CMW-KE400, for "Dual Carrier Fading" also R&S CMW-KS404.
●
Dual Carrier HSPA
:
A UE configured with two adjacent downlink frequencies and two adjacent uplink
frequencies supporting dual carrier R9 HSDPA in the downlink and dual carrier
HSUPA in the uplink. As specified in 3GPP TS 25.319, section 9, only 2ms TTI
frames are supported for the dual cell E_DCH operation.
Carrier 1 and carrier 2 use the different input/output paths of two different SUWs.
Many parameters can be configured individually per carrier.
Note that while the dual cell E-DCH operation is configured, dedicated channels
(DCH) are not supported. Additionally, there is no multi-band support in the "Dual
Carrier HSPA", see
