4.3 RF TX Modulation Test Demonstration

In this demonstration, the user can transmit Wi-Fi® standard packets with the WILCS02_WINCS02.

Perform the following steps for the demonstration of the RF TX modulation test:
Figure 4-6. RF TX Modulation Test
  1. In the RF tab, perform the following steps:
    1. From the “Channel” drop-down list, select 2442 MHz for channel 7.
    2. From the “Rate Type” drop-down list, select Legacy for 11b and 11g mode or MCS for 11n mode.
    3. From the “Data Rate” drop-down list, select 1 Mbps – 11b for 11b mode and 1 Mbps.
    4. Load From File: Load the calibration file (.cfg file) and click Commit To Device, if necessary.
    5. Apply Flash Cal. : If the calibration file is loaded and committed to Flash, click Apply Flash Cal. to apply the calibration parameters in Flash.
  2. In the TX Modulation tab, perform the following steps:
    1. From the “Power Mode” drop-down list, select Index for manual input gain index, TPC Once for enabling TPC.
      • Select the “Gain Index” value from 0-115.
      • From the “Power Mode” drop-down list, select TPC Once to read values from gain table for the transmission.
    2. Retain the “Duration” as 9999 (default value).
    3. Retain the “Frame Length” as 1500 (default value).
    4. From the “GI Mode” drop-down list, select Long for long GI and Short for short GI.
    5. Retain the “CCA Mode” as Disable (default value).
      • Enter the “Busy Value (dBm)” when “CCA Mode” is Enable (-62 is default value).
      • Enter the “Clear Value (dBm)” when “CCA Mode” is Enable (-82 is default value).
      • Click Set CCA Threshold to change the CCA threshold value, if necessary.
    6. Click Start TX to transmit Wi-Fi packets as configured parameter. Use the Wi-Fi tester to verify the transmitting packets.
    7. Click Stop TX to stop the transmission.
