Hi,
I am using WL1273 module with custom AM335x board, and ti-sdk-am335x-evm-06.00.00.00.
In Rx Testing by calibrator, Invalid OFDM 64QAM output detected.
The details are as follows:
For testing EVM(Error Vector Magnitude) under conditions below,
---------------------------
mode:IEEE802.11a
Chanel:120ch
Rate:54Mbps
power:12dBm
modulation:OFDM 64QAM
---------------------------
Executed calibrator commands below:
------------------------------------------------------------
calibrator wlan0 plt power_mode on
calibrator wlan0 plt tune_channel 1 120
calibrator wlan0 plt tx_cont 100 0x1000 2284 0 12000 0 3 0 0 4 0 0 1 0 de:ad:be:ef:00:00
------------------------------------------------------------
Then packets captured in specified channel, rate, size, MAC address.
But result of OFDM 64QAM analysis, Invalid OFDM 64QAM outputs detected.
(See attached file. They are inside Red circles)
Same problem occurs in another channels, e.g. 11g 1,6,11ch, 11a 36,48,64,100,120,140ch.
It seems to be caused by invalid radiowave output outside 54Mbps OFDM.
Q1:
My calibrator commands are correct?
If not, let me know correct commands.
Q2:
Is there similar problems in past?
If there is in past, let me know the cause and how to avoid it.
Regards,
