802.11n - 40MHz - Mod and Power
C Measurement Library

WLAN_Meas_Lib_C_Ex11 - 802-11n - 40MHz - Mod and

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
  • Power Profile
      Average Power
      Peak Power
      Burst Length
      Rising Edge Time
      Falling Edge Time
    Modulation Accuracy
      System Type
      Modulation Type
      Data Rate
      HT Format
      HT MCS
      EVM RMS
      EVM Data Carriers
      EVM Pilot Carriers
      RCE RMS
      RCE Data Carriers
      RCE Pilot Carriers
      Frequency Error
      Symbol Clock Error
      Carrier Leak
      IQ Gain Imbalance
      IQ Skew
      Number of PSDU Bits
      Number of PSDU Symbols
    Spectral Flatness
  • 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:

Aeroflex 3011 RF Synthesizer PXI module
Aeroflex 303xC RF Digitizer PXI module

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)
