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. You can do this in one of two ways. Enter a known one dimensional array variable such as “NumM”. The program variable “NumM” is a
from the variable you enter into the window unless you press one of the other two Set Scalar buttons.
Make your own Scalar array. Enter the Start, Stop, NumPts such as
Frequencys in the windows below the Scalar switch. Remember if switch is in the up position Scalar will still be used for the number of rows but not written to the output file.
Notice there is also a SET SCALAR button below column 2. You may choose to set the number of rows using the size of column 2.
This will set Scalar and if Scalar is present in column 1 window and switch 1 isin the down position then the output file will include the row count or whatever.
Any one of the switches in the up position will skip that parameter in the output file. Note that for basic Antenna rotation measurements the frequency is constant while the path loss and angle is the program measurement complex variable “Adata”. I you wanted to create a text
based output file for a spreadsheet which contains the results of a rotation and measurement set then set all switches tothe up position except for switch 2 (or 3 or 4 or 5). Then enter Adata into window 2 below switch 2. Press the Set Scalar button in column 2. Then export the data. The resulting text file will contain two columns. Column 1 = Magnitude and column 2 will contain the position. Open the file with Note Pad and use copy & paste to transfer into spreadsheet. If you wanted column 1 to contain the row count then use Set Scalar in column 1. Enter the number of measurements (n)from page 1 software (in the slider window) and a start stop(n) number. Then export. stop number (1
Notice that there are “From Variable” “From Disc” check boxes below each Complex switch. When From Variable is checked the data is retrieved from the variable in the box below the switch at the time of export.
When From Disc is checked you are prompted for a disc data file name at the time of export. The disc file format is that used by VeePRO complex measurement format ie. (Mag, @Ang) in a single column. This proves
invaluable for a wide variety of vector measurements from VNA’s.
