advantage of running with an AcquireDelay of 0 is the FIR filter can run with a
relatively high FIR Tap value to provide stable and timely data. The advantage of
using a greater AcquireDelay is power consumption can be reduced, assuming the
SampleDelay is no less than the AcquireDelay.
SampleDelay
The SampleDelay is relevant when the Continuous Acquisition Mode is selected. It is
the time delay, in seconds, between completion of the TCM sending one set of data
and the start of sending the next data set. The default is 0 seconds, which means the
TCM will send new data as soon as the previous data set has been sent. Note that the
inverse of the SampleDelay is somewhat greater than the actual sample rate, since the
SampleDelay does not include actual acquisition time.
7.3.25 kGetAcqParams (frame ID 25
d
)
This frame queries the unit for the acquisition parameters. The frame has no payload.
7.3.26 kSetAcqParamsDone (frame ID 26
d
)
This frame is the response to kSetAcqParams frame. The frame has no payload.
7.3.27 kGetAcqParamsResp (frame ID 27
d
)
This frame is the response to kGetAcqParams frame. The payload has the same structure
as kSetAcqParams.
7.3.28 kPowerDownDone (frame ID 28
d
)
This frame confirms the TCM received a command to power down. The frame has no
payload.
7.3.29 kFactoryMagCoeff (frame ID 29
d
)
For the current designated kMagCoeffSet, this frame clears the magnetometer calibration
coefficients and loads the original factory-generated coefficients. The frame has no
payload. This frame must be followed by the kSave frame to save the change in non-
volatile memory.
7.3.30 kFactoryMagCoeffDone (frame ID 30
d
)
This frame is the response to kFactoryMagCoeff frame. The frame has no payload.
