For example:
============
1. Check EVM & Power
	iwpriv ra0 set ATE=STASTOP				; Stop STA working
	iwpriv ra0 set ATEDA=00:11:22:33:44:55
	iwpriv ra0 set ATESA=00:aa:bb:cc:dd:ee
	iwpriv ra0 set ATEBSSID=00:11:22:33:44:55
	iwpriv ra0 set ATETXRATE=11				; Set Tx Rate 0~11
	iwpriv ra0 set ATECHANNEL=1				; Set Ate channel
	iwpriv ra0 set ATETXLEN=1024			; Tx frame length(no include 802.11 header)
	iwpriv ra0 set ATETXPOW=18				; Tx power(decmial)
	iwpriv ra0 set ATETXCNT=100000			; Tx frame count(decmial, this value must
											; larger than meausurement period)
	iwpriv ra0 set ATE=TXFRAME				; Start Tx Frame
	...										; Measure EVM and Power with instrument
	iwpriv ra0 set ATETXPOW=19				; dynamic adjust Tx Power in decmial
	...
	iwpriv ra0 set ATETXPOW=20
	...
	iwpriv ra0 set ATE=STASTOP				; Stop


2. Check Carrier
	iwpriv ra0 set ATE=STASTOP
	iwpriv ra0 set ATETXRATE=11				; Set Tx Rate 0~11
	iwpriv ra0 set ATETXCNT=50				; Tx frame count(decmial)
	iwpriv ra0 set ATE=TXFRAME				; Start Tx Frame(inform BBP to change 												; modulation mode)
	iwpriv ra0 set ATE=TXCARR				; Start Tx carrier
	...										; Measure carrier with instrument
	iwpriv ra0 set ATE=STASTOP


3. Check specturm mask
	iwpriv ra0 set ATE=STASTOP
	iwpriv ra0 set ATETXRATE=11				; Set Tx Rate 0~11
	iwpriv ra0 set ATETXCNT=50				; Tx frame count(decmial)
	iwpriv ra0 set ATE=TXFRAME				; Start Tx Frame
	iwpriv ra0 set ATE=TXCONT				; Start continuous TX
	...										; Measure specturm mask with instrument
	iwpriv ra0 set ATE=STASTOP


4. Frequency offset tuning
	iwpriv ra0 set ATE=STASTOP
	iwpriv ra0 set ATETXRATE=11				; Set Tx Rate 0~11
	iwpriv ra0 set ATETXCNT=50				; Tx frame count(decmial)
	iwpriv ra0 set ATE=TXFRAME				; Start Tx Frame
	iwpriv ra0 set ATETXFREQOFFSET=0		; Set frequency offset 0(decimal)
	iwpriv ra0 set ATE=TXCARR				; Start Tx carrier
	...										; Measure carrier frequency with instrument
	iwpriv ra0 set ATETXFREQOFFSET=10		; Dynamic turning frequency offset 													; 10(decimal)
	...                                 	
	iwpriv ra0 set ATETXFREQOFFSET=20		; Dynamic turning frequency offset 													; 20(decimal)
	...                                 	
	iwpriv ra0 set ATE=STASTOP				; Stop
											; Store the tuning result to EEPROM


5. Rx
	iwpriv ra0 set ATE=STASTOP
	iwpriv ra0 set ResetCounter=0			; Reset statistic counter
	iwpriv ra0 set ATETXRATE=11				; Set Tx Rate 0~11
	iwpriv ra0 set ATE=RXFRAME				; Start Rx
	...										; Transmit test packets
	iwpriv ra0 set ATE=STASTOP				; Stop
	iwpriv ra0 stat

6. Hardware access
	iwpriv ra0 bbp 0						; read BBP register 0
	iwpriv ra0 bbp 0=12						; write BBP register 0 as 0x12
	iwpriv ra0 mac 0						; read MAC register 0
	iwpriv ra0 mac 0=1234abcd				; write MAC register 0 as 0x1234abcd
	iwpriv ra0 e2p 0						; read E2PROM 0
	iwpriv ra0 e2p c=12ab					; write E2PROM 0xc as 0x12ab

	
Suggestion:
============
	1. To turn on ATE functionality, you have to add compile flag "DBG" and "RALINK_ATE" to Makefile
	2. Before doing ATE testing, please stop STA function (iwpriv ra0 set ATE=STASTOP)
	3. If you want to test another ATE action, prefer to stop STA & ATE function (iwpriv ra0 set ATE=STASTOP)
	4. All ATE function settings will lose efficacy after reboot.
	5. Before hardware register access, please reference hardware spec.

*Note.
======
	1. In ATE mode, the channel must set via "ATECHANNEL"

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

• Expand the archive file (if the download file is in zip or rar format).

• If the expanded file has an .exe extension, double click it and follow the installation instructions.

• Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

• Find the device and model you want to update in the device list.

• Double-click on it to open the Properties dialog box.

• From the Properties dialog box, select the Driver tab.

• Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
