Acquisition rate

Speed mode
MXFS operates with two different speed modes that correspond to two
sweeping laser speeds:
S
High Speed mode: 2000 S/s
S
Low Speed mode: 100 S/s
Information
Changing the speed mode will restart the device.
It can operate at these data rates or considering a lower number of samples by
filtering or down sampling.
Please check
section 4.2.1 “Sample rates”, page 46
for more details.
Information
Changing speed modes is only possible to perform via catman software.
3.6.2
Distance effect
For sweeping laser based Optical Interrogators, such as the BraggMETER
from HBK FiberSensing, there is an effect of the length of cabling between the
interrogator and the sensor on the measured of the reflected measurement.
This effect is a constant shift in the wavelength measurement that depends on
the actual sampling rate of the optical module. The shift on the measured
wavelength is negligible for low acquisition rates or short distances but
becomes important for high sampling rates or long distances.
