board_type

Base Table | Station_Datalogger_PChannel
Attribute Name | board_type
ColumnName | board_type
Logical Rolename |
RoleName |
Definition | This attribute describes the board type on the datalogger where the physical channel resides. Regular seismic channels are usually on a primary board. Auxiliary channels (internal temperature, external power, …) are usually on an auxiliary board. A value of external is used to represent a digitizer that is not part of the datalogger (for example an embedded digitizer in a digital pressure sensor). A digital board is used to represent truly digital sensors which don’t actually have any digitizing stage from Volts to Counts (for example a rainfall sensor that uses a digital counter)

channel_type

Base Table | Station_Datalogger_PChannel
Attribute Name | channel_type
ColumnName | channel_type
Logical Rolename |
RoleName |
Definition | This attribute describes the type of the input channel. An input channel is usually classified as physical when the data is digitized (velocity, acceleration, ...). An input channel is defined as synthetic when the data is not derived directly from a sensor (clock frequency, available telemetry buffer channel, clock quality, ...)
