30 Data Processing Introduction The Data Processing Feature is your gateway to unlocking the data contained within your antenna measure- ments. After making your initial measurement of the Antenna you.
31 Data Registers When working with data in the Data Processing feature all of the data is stored in registers, these regesters alow you to have “Holding Space” for partictular data sets. this is very useful for working with multiple measurements from other antennas.
32 Visualization Options The data visualuzation options enables you to view the Antenna Data in a wide variety of formats. Azmuth vs. Frequency vs. Amplitide 3D Plot Azimuth vs. Elevation vs. Amplitude 3D Plot About: This plot is the most versatile of the 3D plots and will gve you a good idea of the frequency response Vs.
33 Dynamic Amplitude Plot Dynamic Polar Plot Group Delay Function About: This plot of fers a Linear or Log Mag 2D look into the Gain Pattern of the measured Antenna for a specified frequency point.
34 Measurement Calculator Use this option to perform arithmetic operations on the measurement registers. For example if you make mea- surements on one antenna and wish to compare the results to another antenna at each point of rotation and each fre- quency .

36 Important---- If you are using a VNA this information does not apply to you. Performing a Scalar Calibration 1. Be sure Platform Power supply is securely attached and plugged in 3. Turn Platform Power ON. 4. Selet the Source Instrument you plan to use, After selection click the “Settings” button located below the icon.
37 Making a basic Horizontal/Azimuth Measurement 1. Be sure Platform Power supply is securely attached and plugged in 2. Attach antenna to rotator platform with SMA connector 3. T urn Platform Power ON. 4. On your analyzer select S21, POLAR Plot and the proper Calibration set Example: 4 to 6 Ghz @ 201 Points.
38 Chapter 3 - Making Measurements Az/El Scan Measurements Performing an AZ/EL Scan Measurement 1. Be sure Rotator Power is Securely attached and plugged in 2.

40 Chapter 4 - Using the Data Processing Feature Introduction Use the Data Proceessing section to work with the data you collected after you make any Antenna Measurements.
41 Saving and Loading Measurement Data Sets. All Measurement Data is stored in Data Sets, each Data Set consists of a group of 4 Data Registers. These 4 Registers are used only for storing and recalling data within the Data Processing feature, the Data Sets can be recalled or saved to disc at any point in time.
42 Viewing and working with measurements in 3D Press any of the 3D Buttons to View the “Active Register” Data in 3D Using the MatLab V iewing Interface.
43 Viewing and working with the Dynamic Amplitude Plot 1 . From the Main Data Processing Page click on Amplitude Frequency Plot and you will be taken to the screen shown below 2 . Select Log or Linear Data V iew . 3 . Click “Auto Scale” to view all of the data 4 .
44 V iewing and working with the Polar Plot display 1. From the Main Data Processing Page click on “Polar Plot” and you will be taken to the screen shown below 2. Select Log or Linear Data View . 3. Click “Auto Scale” to view all of the data 4.
45 Using the Measurement Calculator / Register Math Function. Understanding the Register Math Functions Measurement data is initially stored in the Active registerwhen you leave the main software page and enter the advanced processing section.
46 Using the Measurement Calculator / Register Math Function. Contd. Clip Function Use this to create a threshold level. A ZERO value clip causes software to ignore clipping and resume normal calculator mode. For example lets say the you wish to not include data points smaller than some low level value such as <-50dBM.
47 Exporting Data Measurement Export Process V ARIABLES : - All variables are single column arrays Scala r = The first real array toggled by switch 2 to be written to disc A real array used to establish the number of rows for all switches for export NumM = A real array which contains the number of measurements.
48 Adata is your measurement data array in complex format from the baisc page 1 software The first column is a scalar array and can set the count for example “frequencies” or angle. Y ou can do this in one of two ways. Enter a known one dimensional array variable such as “NumM”.
49 Using the Dipole and Isotropic Link Calculator- Use the ideal dipole to simulate an entire link measurement set. Then you may perform calculator operations that you can use to normalize and compare your measurements to. The calculations are for any dipole length over any frequency range for any rotation sequence.
50 Once you have saved your dipole array into REG1 (or 2,3,4) calculate the Aperture array and save the results into REG2. Now use the calculator to multiply REG1 x REG2. The result is the entire link gain normalized to the Rx antenna gain. Save the results into a REG3.
51 Data Processing Feature Group Delay Function Group delay is the derivative (slope) of the transmission phase angle. For passive circuit elements the group delay is linear and may be calculated from two measurements. It is important that the ratio of the frequency delta- wavelength is less that the physical distance between the measurement.
