Glossary
Spectrophotometer
– A complete system for making spectral measurements. The
system includes a light source, means for collecting light that has interacted with the
material under test, and a spectrometer to measure the collected light.
Spectrometer
– Instrument to measure the quantity of light over a spectrum of
wavelengths. The spectrometer is the "measurement engine" of the spectrophotometer.
Auxiliary Data
(in system check and acquisition)
Number Name Description
0 UTC Universal Time Coordinated hhmmss.cc
hh = hours, mm = minutes, ss = seconds,
cc = hundredths of seconds
1 Long GPS Longitude
2 Lat GPS Latitude
3 Alt GPS Altitude
4 Speed Speed (Km/h)
5 I Current used to calculate EC data
6 Vsh Voltage shallow
7 Vdp Voltage deep
8 Soil temp Soil temp
9 X/force Spare for Shank mode or force for probe mode
10 Y Spare
11 Z/depth Spare for Shank mode or depth for probe mode
12 Spec temp Spectrometer case temperature
13 Side temp Side control box on spectrometer temperature
14 Spec hum. Spectrometer case humidity
15 Aux temp Auxiliary temperature

17 Steps Steps shank moves during dark/reference check
Program state
– Indicates the current program state. This can either be REST, DARK,
REF, SAMPLE, or LOG.
REST – System can either LOG data or SAMPLE data.
DARK
– Shank cuts off light from the spectrometers and stores a dark spectrum.
REF – Shank moves reference material in front of window and stores a ref
spectrum.
SAMPLE
– Program is storing spectrum data for material placed under shank
window.
LOG
– Program is logging field data this includes spectrum data and auxiliary
data.
All temperatures are
in degrees C.
Shank steps should
be 5.2 cm within +-
.03 cm.
If no data is
present for an
auxiliary data item a
–1.50 will be output.
