7.16 WAVEFORM SPECIFIC OBSERVATION ID SUFFIXES
Each waveform channel in a recording contains timing, channel definition and digital time series data. The category of waveform result transmitted in a given OBX segment is determined by the Observation ID Suffix contained in OBX-3-observation identifier. Four suffixes are provided for the different categories of waveform result:
Observation |
Suffix |
Data Type |
Timing Information |
TIM |
TS |
Channel Definition |
CHN |
CD |
Waveform Data |
WAV |
NA or MA |
Waveform Annotation |
ANO |
CE |
The Observation Sub-ID is used to associate the TIM, CHN, and subsequent WAV, and ANO category result segments for a given channel or channels in a waveform response message.
