2) 2G / 5G: calibrated frequency band

According to the antenna of DUT, set the calibration frequency band correctly. The

options are:

WIFI_2.4G, WIFI_5G, WIFI_ALL, BT and ZIGBEE.

For example, the antennas of 2.4G and 5G are separated,

WIFI_2.4G or WIFI_5G

should be selected separately.

3) VSG power: transmit power during calibration

The unit is dBm. There are four options: 0, -5, -10, and -15.The default value -10 is

generally selected.

4) DUT ID: corresponding to RF port of tester that connected to DUT

The range is [1, 8], 1: The RF1 port connected to DUT; 2: The RF2 port connected DUT,

and so on.

5) VSG RF PORT:

There are eight options: RF1, RF2, RF3, RF4, RF5, RF6, RF7, and RF8.

6) VSA RF PORT:

There are eight options: RF1, RF2, RF3, RF4, RF5, RF6, RF7, and RF8.

．

2.4G / 5G attenuation compensation

Compensate the attenuation value of the external cable that cannot be calibrated, such as IPX

cable. The final attenuation value will be automatically added to the compensation value.

．

Attenuation calibration switch

There are two states: "START" and "STOP", which respectively indicate the start and end of

automatic alignment.

．

Auxiliary cable calibration

Auxiliary cable calibration configuration item. If the RF cable in the shielding box is short and

cannot be looped back, an auxiliary line is needed at this time.

3.2.2. Calibration Instructions

3.2.2.1. General Calibration

To automatically attenuation calibrate the external attenuation value:

1) Connect the two ends of the RF cable to the two RF ports of tester, such as RF1, RF2, as

shown in the figure below.

Figure 3-11 Automatic attenuation calibrate environment

2) Configure the “DUT CHAIN”

Configure the “DUT CHAIN” according to the DUT antenna connected.

3) Configure the frequency band to be measured

Configure the “2G / 5G” according to the frequency band of the DUT antenna connected.

4) VSG Power defaults to -10dBm.

-16-

4) DUT is connected to the tester via RF cable.

 If it is a multi-antenna DUT, please combine multiple antennas to the same RF port of the

tester through power divider.

5) Verify that the IP address and test RF port of the tester in “WT_TESTER.txt” are configured

correctly, as shown below.

Table 4-1 Tester information configuration for normal test

Command Description

WT_IP_ADDRESS

Tester IP address.

WT_DUT_START_NUM

Test RF port of tester.

6) Verify the DUT initialization information in “WT_DUT_MIMO.txt” is configured correctly, such

as IP address, username and password for Telnet login, response characters, etc.

7) The following will explain how to set up a test environment according to different

communication interfaces. For the configuration of other test indicators, see "5. Configuration

Instructions" below.

4.1.1.2. Telnet / SSH / TCP Communication

The following configuration needs to be modified in “WT_DUT_MIMO.txt”.

Table 4-2 DUT information configuration for Telnet / SSH / TCP communication during normal test

Command Description

WT_DUT_IP_ADDRESS DUT IP address in test mode.

WT_SUB_IP_ADDRESS_n

(n is an integer, the range is [1, 8])

Sub IP address configuration item.

Please block these items, that is, add "//" before them.

WT_DUT_LOGIN_NAME

WT_DUT_LOGIN_PWD

WT_DUT_CONN_PORT

WT_DUT_ACK_TOKEN

The response character of DUT.

 Telnet communication can be viewed by manual Telnet.



SSH communication can be viewed after logging in

through Putty software.

 TCP communication response character is empty

WT_DUT_INIT_START

Begin execution of the DUT initialization instruction.

WT_DUT_INIT_END

End execution of the DUT initialization instruction.

Used in conjunction with “WT_DUT_INIT_START”. The

initialization instruction is configured between these two

statements. The configuration format of the initialization

instruction is as follows.

[Initialization instruction] [Response character after executing

initialization instruction] [Timeout time], timeout unit is ms.

WT_DUT_IF_2G

2.4G network name of the DUT. After successful login, you can

view it through the ifconfig command.

WT_DUT_IF_5G

The 5G network name of the DUT. After successful login, you

can view it through the ifconfig command.

For examples:

 Actual test environment

 Tester IP address 192.168.10.254

 DUT supports 2.4G and 5G , 2.4G network name: ra0, 5G network name: rai0

 DUT IP address: 192.168.1.1

 DUT login port: 23, username: admin, password: admin, response character: [CMD>]
