Parameter
Name/Value
Description
3
QPSK
Specifies the channel’s modulation scheme is QPSK.
QAM16
Specifies the channel’s modulation scheme is QAM16.
This choice is available only for channels with a symbol rate of 240000.
Only when ‘HSPA’ functionality is operative, ‘QAM16’ parameter is allowed.
QAM64
Specifies the channel’s modulation scheme is QAM64.
This choice is available only for channels with symbol rate 240000.
Only when both ‘HSPA’ functionality and ‘HSPA+’ functionality are operative,
‘QAM64’ parameter is allowed.
Mode
WCDMA
Remote Command
[:SENSe]:RHO:SBOundary:LIST[:BTS]:INIT <symbol_rate>, <code_num>, QPSK
| QAM16 | QAM64
Example
In order to predefine the following channels:
- CPICH (C8(0))
- P-CCPCH (C8(1))
- S-CCPCH(C8(3))
- PICH(C8(16))
- HS-DPCCH (C4(15)) 16QAM modulated

Notes
This command is effective when [:SENSe]:RADio:DEVice is set to BTS and
[:SENSe]:RHO:SBOundary[:BTS] is set to CUSTom.
QAM16 for the 3rd parameter is available only when HSPA Enable is On.
QAM64 for the 3rd parameter is available only when both HSPA Enable and HSPA+ Enable are on.
