Trend can display also actual signals if they are stored to a database.

Analysator
nmas Analysator software is used for data analysis. nmas Analysator software
has a wide range of tools for performing analysis for different signals.
Analysator software has been built mainly for analyzing vibration data but can
be used for viewing other time based signals also.
Read nmas Analysator manual for more information.
Configurator
nmas Configurator software is used for configuring measurements by user.
Read nmas Configurator manual for more information.
Signal processing
Analog-to-digital converter
Nmas uses AD-converters to convert analog sensor signal to digital format.
Analog-to-digital conversion is done in nmas SU (Sensor Unit). Nmas uses
different conversion rates for high and low frequency signals.
All high frequency signals in one unit are measured at the same time. When
using tacho it is also measured simultaneously with signals.
All high frequency signals are also measured continuously in all channels.
Continuous measurement gives the possibility to trace all phenomena in device
under measurement.
For low frequency signals analog to digital conversion is done channel by
channel. This is generally described as multiplexed measurements. This means
that data from different channels have small difference in time domain.
High and low frequency signals are measured with different AD-converters.
Digital signal processing can be done in hardware and software levels.
Hardware level signal processing is done immediately after the signal is
measured. See chapters “figures” and “warnings and alarms” for more
information.
Typical high frequency signals are vibration, acoustic emission and proximity
signals.
Typical low frequency measurements are temperature and pressure.
