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 4th parameter is available only when HSPA Enable is On. QAM64 for the 4th
parameter is available only when both HSPA Enable and HSPA+ Enable are on.
The maximum number of entries is 512.
Default value of the parameter
By default, one channel is defined. (CPICH C8(0))
In order to query the default entry, specify 1 for <entry_id>:
:SENSe:RHO:SBOundary:LIST:BTS:CHANnel? 1
The instrument returns an array of three values:
15000, 0, QPSK
Query command needs <entry_id> parameter
The <entry_id> parameter is always required for a query command.
The range of the parameter is from 1 to the total number of channels you have defined.
For example, if you have defined two channels, you can query them as follows:
:SENSe:RHO:SBOundary:LIST:BTS:CHANnel? 1
:SENSe:RHO:SBOundary:LIST:BTS:CHANnel? 2
If you want to know the number of channels you have defined, send the following query command:
:SENSe:RHO:SBOundary:LIST:BTS:NCHannels?
Error messages associated with this parameter. The following error message is logged if the given
parameter is invalid. If an error is reported, the SCPI command is rejected and the instrument’s
settings do not change:
(1)<entry_id> out of range
The entry ID must be:
1 <= entry_id <= The number of entries that are currently appended.
