C Analysis Library
This example demonstrates the use of the LTE Uplink (FDD) Measurements Library
DLL interface in Microsoft C to perform Spectrum and Modulation Accuracy measurements.
It makes measurements of EVM RMS, Occupied Bandwidth, Spectrum Mask and CCDF:
It assumes that the following has been installed successfully:
Aeroflex 3010 RF Synthesizer PXI module
Aeroflex 303x RF Digitizer PXI module
Aeroflex PXI Module Software - V6.6.0 or better
Aeroflex LTE Uplink Measurement Suite - v1.0.0 or better
It is also assumed that:
The 3010 LO output is connected to the 3030 LO input
The 303x IF output is connected to the 303x IF input (if applicable)
This is the main project file for VC++ projects generated using an Application Wizard.
It contains information about the version of Visual C++ that generated the file, and
information about the platforms, configurations, and project features selected with the
This is the main application source file.
Other standard files:
Lu01250prb.aiq - Sample ARB file required for LTE UL, to be played by the source
Lu01250prb.iqc - The IQ Creator file used to generate the ARB file
- Refer to IQCreator user Manual to modify file settings
- IQCreator can be downloaded free of charge from the Aeroflex website.
The Outputs are a log file LteUplinkLog.txt and .CSV files that can be opened with MS Excel and used to
create a graph of the Power vs Frequency Spectrum and CCDF measurements.
