IW612ラボツールの質問

[kazus]

1. PRBSは、9次の擬似乱数バイナリシーケンスと同じですか

　PRBS9と同じでしょうか？ (UM11717 P.87, 89)

2. Whiteningの内容を教えて下さい (UM11717 P.87-90 )

3. 受信アンテナ番号のセットコマンドについて、例が異なっている部分があります。

　ミスでしょうか？ 10 0 2 2 // Set both TX and RX to antenna 2(P.27)　→　10 2 2

　(UM11717 P.51-59, 61, 64-66)

4. 802.11b,g,a,n,ac,ax  Tx/Rxのコマンドシーケンスの内容は、順番に入力することで正しいカウント数が得られますか？カウント開始は、どのタイミングでしょうか。

　(UM11717 P.51-60)

Hello Shaun
Thank you for your reply.

Is PRBS the same as a pseudorandom binary sequence of order 9? Is it the same as PRBS9? (UM11717 P.87, 89)
Module certification testing will be performed using PRBS9. Can this be supported?

Please tell me about the Whitening content (UM11717 P.87-90)

There are some differences in the example for the receiving antenna number setting command. Is this a mistake?

10 0 2 2 // Set both TX and RX to antenna 2(P.27)　→　10 2 2　(UM11717 P.51-59, 61, 64-66)

"10 2 2" is not working

Will the correct count be obtained by entering the 802.11b, g, a, n, ac, and ax Tx/Rx command sequence in order? When should the counting start?(UM11717 P.51-60)
Do you use the same module for sending and receiving? Or do you use different modules?

Best Regards

Hello @kazus 

Module certification testing will be performed using PRBS9. Can this be supported?

According to bt specification, it should be PRBS7. Could you share which certification you are passing?

10 0 2 2 // Set both TX and RX to antenna 2(P.27)　→　10 2 2　(UM11717 P.51-59, 61, 64-66)

"10 2 2" is not working

You need hardware antenna configure as dule mode first. Then FEM calibration file should change to dule antenna configure file. 

Do you use the same module for sending and receiving? Or do you use different modules?

Same module, rf tester could rx/tx frames. But at one single test, you can only test tx or rx.

Best Regards

Hello Shaun

The tests will cover EN 300 328, FCC Part 15 Subpart C, and RSS-247.
There do not appear to be any clear provisions for PRBS in the standards, so I will ask the testing organization if PRBS7 is acceptable.

10 0 2 2 // Set both TX and RX to antenna 2(P.27)　→　10 2 2　(UM11717 P.51-59, 61, 64-66)

"10 2 2" is not working

You need hardware antenna configure as dule mode first. Then FEM calibration file should change to dule antenna configure file. 

Understood.
Is "10 0 2 2" the correct single mode setting?

Do you use the same module for sending and receiving? Or do you use different modules?

Same module, rf tester could rx/tx frames. But at one single test, you can only test tx or rx.

Understood.

How do I synchronize transmission and reception in the following cases?

10.1.1 Labtool command sequence for 802.11b Tx

• Tx on channel 1 at 8 dBm target power with CCK-11 Mbps rate in 2.4 GHz band, 20 MHz bandwidth mode on
antenna 1
6 11 // Set radio mode index “11” to test 2.4 GHz band
10 1 1 // Set Tx antenna and Rx antenna to antenna 1
112 0 0 // Set 20 MHz bandwidth
12 0 1 // Set to 2.4 GHz channel 1
35 0 1 4 8 // 2.4 GHz Tx at 11 Mbps at 8 dBm power level
35 0 0 // Stop Tx

10.1.2 Labtool command sequence for 802.11b Rx
• Rx on channel 1 in 2.4 GHz band, 20 MHz bandwidth mode on antenna 2
6 11 // Set Radio Mode Index “11” to test 2.4 GHz band
10 2 2 // Set Tx antenna and Rx antenna to antenna 2
112 0 0 // Set 20 MHz bandwidth
12 0 1 // Set to 2.4 GHz channel 1
31 0 // Clear the received packet count
-Transmit Wi-Fi packets from tester
32 0 // Get Rx packet count and then clear the Rx packet counter

add quesion

Can the above be applied to IW611 and UM11749 as well?

Best Regards

-->We have lots customer pass EU and FCC certification, it should be fine.

Is "10 0 2 2" the correct single mode setting?

--> 10 1 1   // set tx/rx antenna to antenna 1

How do I synchronize transmission and reception in the following cases?

-->Sorry you may misunderstand my point. In rf test mode or MFG mode, chip can not tx and rx synchronous.

Can the above be applied to IW611 and UM11749 as well?

--> iw611 support mfg_mode and rf_test_mode no problem. UM11749 is rf_test_mode guide, not mfg_mode.

Hello @kazus 

Due to I don't understand Japanese, response may not match your question. Please let me know if you have further question about my response.

PRBSは、9次の擬似乱数バイナリシーケンスと同じですか

-->Bluetooth Core Specification recommend to use PRBS7.

受信アンテナ番号のセットコマンドについて、例が異なっている部分があります。

　ミスでしょうか？ 10 0 2 2 // Set both TX and RX to antenna 2(P.27)　→　10 2 2

　(UM11717 P.51-59, 61, 64-66)

IW612 support dule antenna configuration.

 802.11b,g,a,n,ac,ax  Tx/Rxのコマンドシーケンスの内容は、順番に入力することで正しいカウント数が得られますか？カウント開始は、どのタイミングでしょうか。

For labtool only, not support, you have to run cmd step by step. We have co-operation with LitePoint, they development auto calibration software to auto process. 

Best Regards
