Counts and Voltage
The signal input range of the DATA-CUBE³ is ± 2.048V = 4.096Vpp.
For 24 Bit ADC this equals 0.000 000 244 140 625V per count at gain 1 (4.096V / 2e24).
The following table shows the volts per count for different gains:
Gain
Volts per count
1
244.140625 nV
2
122.070313 nV
4
61.035156 nV
8
30.517578 nV
16 (default)
15.258789 nV
32
7.629395 nV
64
3.814697 nV
This represents the value at the input side of the DATA-CUBE³.
Please note that if a BOB is used, the output of the sensor is calculated by multiplication with the denominator
of the dividing ratio given at the BOB. The value of the electromagnetic constant of the seismometer must be
taken into account, too, if the ground velocity is the value of interest.
