The test set's call processing behaviors and protocol message encoding are compliant with the 2002-03 release of the 3GPP R99 specifications.
For HSDPA features (lab application or feature-licensed test application only) , the test set is compliant with the 2004-12 release of the 3GPP Release 5 specifications.
For HSPA features (lab application or feature-licensed test application only) , the test set is compliant with the 2006-12 release of the 3GPP Release 6 specifications.
However, the test set always sends R99 variants of RRC messages unless specific Release 5 or Release 6 parameters need to be signaled.
Refer to the various "Ladder Diagrams" in this online guide for more details about protocol message sequences for specific call processing operations.
The test set's measurements are continually evolved to support 3GPP TS 34.121. See What 3GPP W-CDMA/HSPA Conformance Tests Are Supported? for more details.
