12. Glossary
These terms are used throughout the manual:
A/D Value: the digital representation of the analog voltages in an analog-to-digital (A/D) conversion.
The accuracy of the conversion is dependent on the resolution of the system electronics; higher
resolution produces a more accurate conversion. Also referred to as "bits".
Base Station: The base station is the transceiver that attaches to the host computer and provides
communication between the software and the node(s). It is also referred to as a gateway.
Burst Sampling: a mode of operation in which the node is sampled for a fixed window of time (burst)
and then repeats that window at set intervals. The burst duration and time between bursts is
configurable. Also referred to as periodic burst sampling.
Calibration: to standardize a measurement by determining the deviation standard and applying a
correction (or calibration) factor.
Configuration: a general term applied to the node indicating how it is set up for data acquisition. It
includes settings such as sampling mode/rate, number of active channels, channel measurement
settings, offsets, hardware gain, and calibration values.
Continuous Sampling: a mode of operation in which the node is sampled continuously until stopped or
sampled continuously for a fixed amount of time.
Coordinated Universal Time (UTC): the primary time standard for world clocks and time. It is similar
to Greenwich Mean Time (GMT).
Cycle Power: a command transmitted to the node to reboot it either through a hardware or software
switch.
Data Acquisition: the process of collecting data from sensors and other devices.
Data Logging: the process of saving acquired data to the system memory, either locally on the node or
remotely on the host computer.
DHCP (network): Dynamic Host Configuration Protocol is the standardized networking protocol used
on Internet Protocol (IP) networks, which automatically configures devices that are attached to it by
assigning and configuring the device IP address.
EMI: Electromagnetic Interference is an inductive or radiated disturbance that can create signal
degradation on electrical signals, including loss of data.
