NET Option
aka. DEWESoft NET, DEWE NET
With DEWE-NET your measurement system can be controlled remotely with ease of use you couldn't imagine before.
DEWE-NET also serves as the centre of Distributed Data Acquisition systems where you have multiple systems located
either together or scattered across an entire continent. IRIG and GPS time will take care that data will stay
synchronised, no matter how long the acquisition runs.
OS
An operating system (OS) is a set of system software running on a device that manages the system hardware.
This may refer to the operating system of a PC (Windows is required for DEWESoft®) or to the operating system of the
SIRIUS® system.
PC
SIRIUS® systems are typically connected to a Personal Computer which runs DEWESoft® to fetch the measurement
data.

RMS
Root Mean Square (RMS), also known as the quadratic mean, is a statistical measure of the magnitude of a varying
quantity. It is especially useful when variates are positive and negative, e.g., sinusoids. RMS is used in various fields,
including electrical engineering.
RTD
Resistance thermometers, also called resistance temperature detectors or resistive thermal devices (RTDs), are
temperature sensors that exploit the predictable change in electrical resistance of some materials with changing
temperature; e.g. Pt100 and Pt1000
SNR
Signal to Noise Ratio (SNR) is the ratio of the RMS value of the full scale input range to the total RMS noise measured
with the inputs shorted together. The value for SNR is expressed in decibels (dB).
SNTP
Simple Network Time Protocol (SNTP) is a protocol for synchronising the clocks of computer systems over packet-
switched, variable-latency data networks. It is a simpler and less accurate version of the Network Time Protocol (NTP).
Synchronisation cable
These synchronisation cables can be used to synchronise several
SIRIUS® chassis with each other: see 8.2 Synchronisation for
details.
