3.2.2.2. Verify Rx performance

Set the instrument to Tx packets, and DUT MP Rx the packets.

Then parsing the error rate to verify Rx performance.

The following steps are the Rx performance verify command sample :

Step 1 : Start SW(Software) Rx

Example : Verify path A, MCS7, bandwidth 40, CH10 Rx.

rtwpriv wlan0 mp_start //Start MP mode

rtwpriv wlan0 mp_channel 10 //Set Rx channel

rtwpriv wlan0 mp_ant_rx a //Set path a

rtwpriv wlan0 mp_bandwidth 40M=1,shortGI=0 //Set bandwidth

//40M40M=1, 20M40M=0, 80M40M=2

rtwpriv wlan0 mp_arx start //Start Rx

rtwpriv wlan0 mp_reset_stats //Reset the Rx report

Instrument Tx packets at MCS7, bandwidth 40, CH10 and

adjust the Tx power let DUT input power < -61dBm (MCS7-B40 criteria).

Step 2 : While the instrument Tx is finished, parsing the Rx report.

rtwpriv wlan0 mp_arx phy

The command will report Rx OK/CRC_error counter.
