Programming an HSDPA Block Error Ratio Measurement

Last updated: January 16, 2009

This section is only applicable to the lab application or a test application with the required feature license.

This example is forFDD Test Operating Mode . The measurement is also available inActive 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:

Set the HSDPA BLER setup parameters as desired using the SETup:HBLerror commands.
Use theINITiate:HBLerror command to start the measurement.
Use the FETCh:HBLerror query to obtain the measurement results (or use theREAD:HBLerror? command to both initiate and fetch the measurement as a sequential operation).
