CHANNELS...
Calling an operating menu for the configuration of extended functions of the
digital standard 3GPP W-CDMA. The menu item is available only if option
SMIQB48 is installed. For more details on this menu see section "Enhanced
Functions for Digital Standard 3GPP W-CDMA".
OVERALL SYMBOL
RATE
Overall data rate of all uplink DPDCHs. The structure of the DPDCH table
depends on this parameter. The overall symbol rate indicates the active
DPDCHs, their symbol rate and the channelization codes used (see table
further down).
Value range: off, 15 ksps, 30 ksps, 60 ksps, 120 ksps, 240 ksps, 480 ksps, 960
ksps, 2 x 960 ksps, 3 x 960 ksps, 4 x 960 ksps, 5 x 960 ksps and 6 x 960 ksps.
If OFF is selected, the signal only consists of one DPDCH. In this case, no channel
table is displayed.
IEC/IEEE-bus command :SOUR:W3GP:MST1:DPDC:ORAT D60K
POWER PER DPCH
Power of active DPDCHs. Each active DPDCH features this channel power.
The power of the active channels cannot be configured independently (this
also complies with the definition of 3GPP). Value range -60...0.0 dB.
IEC/IEEE-bus command :SOUR:W3GP:MST1:DPDC:POW –23

Note: With an overall rate smaller than 960 ksps only DPDCH1 is active, its rate is equal to the overall rate
and the channelization code is equal to spreading factor/4 (spreading factor = chip rate / symbol
rate). With an overall rate greater than 960 ksps, all active DPDCHs have the rate 960 ksps.
