Roll≤65° of pitch0.2° rms
≤80° of pitch0.4° rms
≤86° of pitch1.0° rms
Resolution0.01°
Repeatability0.05° rms
Maximum Operational Dip Angle (3*)85°
MagnetometersCalibrated Field Range± 125 μT
Resolution0.05 μT
Repeatability± 0.1 μT

(1*) Specifications are subject to change. Assumes the TCM is motionless and the local magnetic field is clean relative to the calibration.
(2*) For example, if the calibration was performed over ±10° of tilt, then the TCM would provide <2° rms accuracy over ±20° of tilt.
(3*) Performance at maximum operational dip angle will be somewhat degraded.

Operating Characteristics

I/O Characteristics

ParameterValue
Communication InterfaceTCM XBBinary RS232 UART
TCM MBBinary CMOS/TTL UART
Communication Rate300 to 115200 baud
Maximum Sample Rate (1*)≈30 samples/sec
Time to Initial Good Data (2*)Initial power up<210 ms
Sleep mode recovery<80 ms

(1*) The maximum sample rate is dependent on the strength of the magnetic field, and typically will be from 25 to 32 samples/sec.
(2*) FIR taps set to “0”.
