EDAS/VIS-SOF. Data Acquisition and Virtual Instrumentation Software:
Compatible with actual Windows operating systems. Amicable graphical frame.
Configurable software allowing the temporal/frequency representation of the different inputs
and outputs. Visualization of a voltage of the circuits on the computer screen.
It allows data store in a file, print screens and reports of the signals at any time.
Measurement, analysis, visualization, representation and report of results.
Set of Virtual Instruments:
Oscilloscope:
Channels: 12 simultaneous. Maximum input voltage: ± 10V.
All 12 input channels could be scaled to compare signal with different voltage levels.
“Math Menu” with operations as Addition, Subtraction, Multiplication and Division, between any of
the 12 oscilloscope channels.
Function Generator:
Two independent signal generators, for sinusoidal, triangular, saw tooth and square.
Channels: 2 (allowing working simultaneously). Maximum output voltage: ± 10V.
It includes a graph where an output signal for each channel is shown.
Spectrum Analyzer:
Channels: 12 (simultaneous). Max. voltage: ± 10V. Spectrum analyzer: based on the FFT.
