This section is only applicable to the lab application or a test application with the required feature license.
This example is for
FDD Test Operating Mode
. The measurement is also available in
Active Cell Operating Mode
.
This section provides an example of how to make HSDPA BLER measurements via remote program. The following program example assumes that the UE is connected to the RF IN/OUT connector.
The basic procedure to test HSDPA BLER is as follows:
INITiate:HBLerror
command to start the measurement.
READ:HBLerror?
command to both initiate and fetch the measurement as a sequential operation). 10 !
