ORBIT FR MiDAS Measurement Suite User Manual
I Software
MiDAS
A high performance software package (ISO
90003:2004) designed for automating antenna test
range systems. MiDAS is a state-of-the-art antenna
measurement software suite, supporting far-field,
near-field (Planar, Cylindrical and Spherical) and
radome measurement systems.
MiDAS
Overview
MiDAS is user-friendly with an intuitive graphic
interface. It comprises an acquisition module that
is used to control the hardware of systems and
manage the test procedures, and an analysis
module that is used to process and plot the collected
data in the acquisition mode most efficiently.
MiDAS operates on Microsoft Win 7 (compatible with
XP OS) and features multi-tasking capabilities.

DATA ACQUISITION MODULE ANALYSIS AND PLOTTING MODULE
The acquisition module has two objectives:
➊ Enables the user to set the antenna measurement
scenario
➋ Runs and automates the measurements
Main features
• Multi axis control with linked axis capabilities
• Supports a wide variety of receivers, signal sources,
spectrums, network analyzers such as Agilent, R&S,
Anritsu
• Continuous, step or spin measurement mode
• Variable aspect sampling (dynamic velocity or
on- the-fly velocity adjustment)
• Diagnostics tools including axis and RF signal control
for a predefined frequency/beam/switch
• Multiple real time display (displays multiple cuts/
frequencies/beams in parallel)
• Unlimited shaped area data acquisition:
defines a discrete collection of points for measurement
• Batch acquisition mode
• Complete setup configuration, including all parameters,
saved in a file
• Redo partial scan on a completed measured file
• Hide/show frequencies (for confidentiality)
• Start measurement with a predefined delay
• Extensive on-line error checking
• Auto repeat scan on error during measurement
• Uncompleted measurement continuing capability in case
of power shut down
• Direct and/or gain transfer calibration capabilities
• Support probe array systems
• Restore a setup file from a measurement data file
The analysis module has two objectives:
➊ Displays the data measured during
the acquisition process
➋ Analyzes the results and displays them
in the graph/table form
Main features
• Data presentation in 2D or 3D plots (including spherical,
contour and polar 3D display)
• Zooming, markers, cursors and different manipulations
on line types, style, etc.
• Value and location display for beam peak, beam width,
sidelobes and null depth (applicable for raw and
transformed data)
• RMS calculation for sidelobes (applicable for
transformed data)
• Comparison of patterns in one or more data files
• Subtract or add two data files at the same time
• Wide selection of options for data averaging (complex,
amplitude/phase, min. and max. of linear and min. and
max. of dB )
• Pass/fail test criteria (for discrete points or patterns)
• Export and import different file formats
• Near-field to far-field data transformation for planar,
plane polar, cylindrical and spherical
• Circular polarization analysis (supports both spinning
and linear modes)
• Back-projection of data from near-field or far-field
• Time domain analysis
• Radome analysis functions
• Slant analysis for a predefined polarization angle
• Echo reduction module (MV-Echo)
• Far-field coordinate -system convertor
