waveformVectorArm
The waveformVectorArm groups three orthogonal components from a site and then does its processing on them as a group.
Example
<waveformVectorArm>
<phaseRequest>
<beginPhase>ttp</beginPhase>
<beginOffset>
<unit>SECOND</unit>
<value>-60</value>
</beginOffset>
<endPhase>ttp</endPhase>
<endOffset>
<unit>SECOND</unit>
<value>360</value>
</endOffset>
</phaseRequest>
</waveformVectorArm>
