WLAN_Meas_Lib_C_Ex09 - CCDF.zip

This example demonstrates the use of the WLAN Measurement Library
DLL interface in Microsoft Visual C++ V6.0 to perform measurements
on a 802.11n 40MHz bandwidth signal:

• Assign digitizer by resource strings
• Set measurement parameters
• Enable required measurements

• Make measurements
• Retrieve measurement results

A DUT or signal generator will need to be generating
802.11n (40MHz bandwidth) RF bursts as follows:-
RF Frequency....: 2000MHz

It assumes that the following has been installed successfully:

Hardware:
=========
Aeroflex 3011 RF Synthesizer PXI module
Aeroflex 303xC RF Digitizer PXI module

Software:
=========
Aeroflex PXI Module Software - V6.9.0 or better
Aeroflex WLAN Measurement Suite - V2.0.0 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)
