LX-80-15 10 Hz Oceanographic Radar Sensor
L4:
The average water level measured by the instrument. The measured water
level depends on the measured distance between the instrument and the
water surface, and on predefined instrument offset which can be adjusted under device
Settings
. The measured water level is filtered using averaging filer, to smooth
the measured data. Filter parameters can be adjusted using the
Geolux Instrument Configurator application under device
Settings
.
S1:
Signal to Noise Ratio of the detected signal. SNR is the difference between signal
level corresponding to measured distance and the noise floor level. Low SNR levels
indicate that the measured value may be inaccurate.
S2:
The standard deviation of water level measurements. The number of samples
used to calculate the standard deviation is equal to the configured filter length. This
parameter is available on units with firmware versions greater than 2.3.2.
CSUM:
The check sum of the characters in the report from $ to * excluding these
characters.
Tilt angle report
$ANG,A1,A2*CSUM <CR><LF>
firmware versions greater than 2.3.5
$ANG:
The keyword sent in the beginning of each angle report.
A1:
The tilt angle of the instrument along X axis. For proper operation of the
instrument, ensure that this angle is zero, or as close to zero as possible (between
-1 and +1 degrees).
A2:
The tilt angle of the instrument along Y axis. For proper operation of the instrument
ensure that this angle is zero, or as close to zero as possible (between -1 and +1
degrees).
CSUM:
The check sum of the characters in the report from $ to * excluding these
characters.
Wave data report
$WAV,H13,HS,HM0,TZ,TZS,TC,TCS,TP,MIN,MAX,AVG,MED*CSUM<CR><LF>
$WAV:
The keyword sent in the beginning of each wave data report.
H13:
The significant wave height calculated as average of one third of waves, in the
currently configured unit (H
1/3
).
HS:
The significant wave height calculated from the standard deviation of water level
points, in the currently configured unit (H
s
).
HM0:
The significant wave height calculated from the zeroth moment of the wave power
spectrum, in the currently configured unit (H
S_M0
).
TZ:
Zero up-crossing period calculated from time-domain water level measurement data,
in seconds (T
ZUC
).
