Parameters
PredefExp is one of the following predefined expressions:
CPICh|IOR. The
default is
CHICh.
Description
This command sets the power type which each code channel is relative to.
Query
The query form of this command returns the current setting for PredefExp
.
Example
:CONF:WCDMA:NB:LEV:REL IOR
:CONF:WCDMA:NB:LEV:REL?
Value returned in this example: IOR
.
NOTE
In remote mode (via SCPI) the power levels of the individual code channels
can only be set relative to I
or
(output power). Furthermore in remote mode
you have to make sure that the sum of the power levels for all code channel
plus OCNS is equal to I
or
.
