2. Choose "Tx packet" for "Test Mode" and set the "WiFi Rate", "BandWidth",
"Channel" and "Attenuation". Tx data rates are listed in Table 4-1.
For example, if the data rate is set to MCS7, bandwidth to 20M, and channel to 1, as
shown in Figure 4-1, you will get the log output described below:
tx_contin_en
tx_contin_en
tx_cbw40m_en
tx_cbw40m_en
3. Click on "stop" to end the Tx process and the returned message is "cmdstop".
4. Before switching to other channels or data rates, please click on "stop" to terminate
