LTE Measurement Example.zip

This example demonstrates the use of the LTE Uplink (FDD) Analysis Library
DLL interface in Microsoft C to perform Modulation Accuracy measurement of
EVM RMS, Occupied Bandwidth and Power vs Time Trace:

      Software steps required:


  • Assign digitizer by resource strings
  • Set External 10 MHz Referecne
  • Set Up Digitizer measurement parameters
  • Set Up LTE Uplink Analysis measurement parameters
  • Make measurements
  • Retrieve measurement results
  • Save IQ data in LteTraceData.csv file and print output log file LteUplinkLog.txt

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)

File reference:

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
Application Wizard.

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.

Output files:

The Output is a log file LteUplinkLog.txt and CSV file called "LteTraceData.csv" that can be opened with
MS Excel and used to create a graph of the Power vs Time measurements.
