Export
Opens the Choose iqw file to export dialog box.
E
nter the path and the name of the IQ data file you want to export. Press ENTER to write the IQ
data into the specified file. If the file cannot be created or there is no valid IQ data to export an
error message is displayed.
Remote: MMEM:STOR:IQ:STAT 1,'C:\R_S\Instr\user\data.iqw'
R&S Support
Creates files that help identifying the current problem. The files are stored under
C:\R_S\Instr\user\Support. If you contact the Rohde&Schwarz support to get help for a certain
problem, send these files to the support in order to identify and solve the problem faster.
EVM Constell
Opens a submenu to select the error vector magnitude (EVM) or the constellation result
displays.
EVM vs Symbol/Carrier
Selects the EVM vs Symbol or EVM vs Carrier result displays.
– EVM vs Symbol (IEEE 802.16–2004 OFDM)
This result display shows the EVM measured over the full range of the measured input data.
The results are displayed on a per–symbol basis, with blue vertical lines marking the
boundaries of each burst. Note that burst boundary lines are only displayed if the number of
analyzed bursts is less than 250. The minimum, average, and maximum traces are displayed.
For the trace labeled with EVM a commonly used EVM definition is applied, which is the square
root of the momentary error power normalized by the averaged reference power. For details of
this measurements please refer to chapter 2.
