Downlink Channel Codes
Downlink Channel Codes can not be changed in Active Cell operating mode (use Cell
Off operating mode to change the active cell downlink channel codes). The downlink channel codes currently
in use are displayed in the Downlink Code Channel Information window.

WCDMA DL Channel Codes
The method for setting downlink DPCH channel codes differs between the test application and lab application.
The following table illustrates the valid channelization codes for each type of DPCH channel, and indicates the
GPIB commands and front panel fields used to set the channelization codes, for both the test application and lab
application (see How Do I Change Generator Information? to help you find these fields from the front panel).

HSDPA/HSPA DL Channel Codes
This section is only applicable to the lab application or feature-licensed test application.
The method for setting downlink DPCH channel codes used during HSDPA and HSPA connections differs
between the test application and lab application. The following table illustrates the valid channelization codes for
each type of DPCH channel used during HSDPA and HSPA connections, and indicates the GPIB commands and
front panel fields used to set the channelization codes, for both the test application and lab application (see How

You can also set the channel code for the following downlink HSDPA and HSPA channels:

Antenna 2 S-CPICH Channelization Code
This setting controls the channelization code of the S-CPICH, which has a spreading factor of 256.
GPIB command: CALL[:CELL[1]]:CPIChannel:SECondary:CCODe:CODE

E-AGCH Channelization Code
This setting controls the channelization code of the E-AGCH. The E-AGCH has a spreading factor of
256.
GPIB command: CALL[:CELL]:EAGChannel:CCODe:CODE

E-HICH/E-RGCH Channelization Code
This setting controls the channelization code of the E-HICH and E-RGCH. These channels have a
spreading factor of 128 and by definition use the same channelization code (see 3GPP TS 25.213
s5.2.1). 40 bit signatures are used to provide orthogonality between the two channels (see HSPA
Downlink Channel Details ).
GPIB command: CALL[:CELL]:EHIChannel:CCODe:CODE

PS Data First HS-PDSCH Channel Code
This parameter sets the channelization code of the first HS-PDSCH when on an HSDPA packet data
connection. If more than one HS-PDSCH is being generated, the other HS-PDSCHs are assigned to the
subsequent channelization codes.
This parameter cannot be set to 5 or 6 when S-CCPCH Channelization Code is set to 26. Also, the
number of HS-PDSCHs specified by the PS Data HS-DSCH Configuration Type , when added to
the PS Data First HS-PDSCH Channel Code cannot exceed 15 (otherwise the HSPDSCHs would collide with the downlink OCNS channels).
GPIB command: CALL:HSDPa:SERVice:PSData:HSPDschannel:CCODe:CODE

RB Test Mode First HS-PDSCH Channel Code
This parameter sets the channelization code of the first HS-PDSCH when on an HSDPA RB Test Mode
connection. If more than one HS-PDSCH is being generated, the other HS-PDSCHs are assigned to the
subsequent channelization codes.
This parameter cannot be set to 5 or 6 when S-CCPCH Channelization Code is set to 26. This parameter
cannot be set to 5 when HSDPA DPCH 12.2k RMC Channelization Codeis set to 45 or 54,
and cannot be set to 6 when HSDPA DPCH 12.2k RMC Channelization Code is set to 54.
Also, the number of HS-PDSCHs specified by the FRC Type or User Defined Number of Active HSPDSCHs settings, when added to the RB Test Mode First HS-PDSCH Channel
Code cannot exceed 16 (otherwise the HS-PDSCHs would collide with the downlink OCNS
channels).

Downlink Channel Code Preset
The downlink channel code preset (front panel: DL Chan Code Preset Configs ) allows you to
configure the test set for 3GPP TS 34.121-1 channel code much easier (the DL Channel Code Preset
Configurations are only available from the front panel; there are no GPIB commands to configure these presets).
The Operating Mode must be set to Cell Off before selecting one of the DL channel code preset
configurations.

Downlink Channel Levels
The relative level of all downlink channels can be individually set or turned off (except that the P-CCPCH and
the SCH are time multiplexed, and use the same level for both channels). The level of each active channel is a
fraction of the Cell Power (Îor) setting, expressed in dB. If the summed level of all channels is less than one,
the orthogonal coded noise source (OCNS) is turned on to account for the difference (see Orthogonal Channel
Noise Simulator (OCNS) ).
The downlink code channel levels currently in use (as well as the "desired" levels) are displayed in the Downlink
Code Channel Information screen.
The downlink channel levels for idle mode (no DPCH is present) may be different than the levels used during a
call (DPCH is present). Thus, there are two different level settings for the downlink channels in active cell
operating mode: Downlink Channel Levels and Connected DL Channel Levels .
Considerations When Setting Code Channel States and Levels




All code channels can be set between 0 and -20 dB, except the relative power level of the DPCH
channel which can be set from 0 to -30 dB.
Any code channel powers that are On must not be greater than 30 dB below the Total RF Power .
The sum of the relative levels of the code channels cannot be greater than 100% of the cell power.
If you set a code channel state to Off , the test set will not automatically turn it back on if it is needed
to perform a call processing operation you've requested (for example, if you turn PICH
Level to Off , the Originate Call procedure will fail).
Downlink Channel Levels
The Downlink Channel Levels set of power levels is used when RRC
State is Idle or CELL_FACH .
These levels cannot be changed in the Active Cell operating mode. You can query these settings via GPIB
and view them on the front panel during Active Cell mode operation, but attempting to change the levels
during Active Cell mode operation results in an error message (use the Cell Off operating mode to
change the active cell downlink channel levels).

Note: no DPCH is generated before the call is established. Setting DPCH Level to a non-zero value
simply adds that power to the OCNS.
GPIB command: CALL:DPCHannel[:SLEVel]
Connected DL Channel Levels
The Connected DL Channel Levels are used when RRC State is CELL_DCH . These levels are applied
after the RRC Connection Setup message is sent by the test set during the RRC Connection Setup Procedure ,
directing the UE to go into CELL_DCH (i.e. once a DPCH has been established). When the DPCH channel is
released, the test set transitions back to the Downlink Channel Levels set.
These levels can be changed in any operating mode, including Active Cell . This allows you to vary the
relative channel levels while a call is connected in order to test the UE's response.
These settings specify the connected downlink channel levels relative to Cell Power (Îor).

Orthogonal Channel Noise Simulator (OCNS)
OCNS is used to simulate additional users on the downlink. OCNS is automatically enabled when the sum of the
levels of all the enabled downlink physical channels is less than the cell power setting.
Cell 1 OCNS is made up of the following 16 separate code channels: 2, 11, 17, 23, 31, 38, 47, 55, 62, 69, 78, 85,
94, 113, 119, and 125, with an OVSF of 128. The fraction of the composite OCNS power that is allocated to
each of the code channels making up the composite OCNS are as specified by 3GPP TS 34.121 sE.3.6.
Cell 2 OCNS ( lab application only ) consists of a single channel at OVSF 128,2.
As individual downlink channel levels are adjusted, the composite OCNS level is automatically set to a value
equal to the difference between the summed downlink channel levels and the cell power setting (when the sum
of the downlink code channel levels is such that the composite OCNS is less than -30 dB, it is set to Off ).
The OCNS currently in use (as well as the "desired" level) is displayed in the Downlink Code Channel
Information window.
GPIB command: CALL:OCNSource (query only)
OCNS in HSDPA/HSPA
This section is only applicable to the lab application or feature-licensed test application.
When HSDPA or HSPA is active (see HSDPA Activation in FDD Test and HSDPA Activation in Active Cell ),
the cell 1 OCNS is made up of the following 7 separate code channels: 122, 123, 124, 125, 126, and 127, with an
OVSF of 128, rather than the code channels described in Orthogonal Channel Noise Simulator (OCNS) above.
The fraction of the composite OCNS power that is allocated to each of the code channels making up the
composite OCNS are as specified by 3GPP TS 34.121 sE.5.2.

The parameter specifies whether S-CPICH is transmitted on antenna 2 when Current MIMO

code will be Serving Cell Primary Scrambling Code . IfAntenna 2 S-CPICH
