通信模块RF测试

發布時間:2024/1/1 编程问答 28 豆豆
生活随笔 收集整理的這篇文章主要介紹了 通信模块RF测试 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

RF主要測試分類:
TX發射:

a) Power Measurement

b) Modulation Analysis

c) Frequency Error Measurement (error within 0.1ppm)


RX 接受:
reveive sensitivity(BER(bit error rate)?messurement)

i) The reciever must be able to decode successfuly the signal coming from a transmitter even though the signal strength is very low.

ii) The reciever must be able to decode successfuly the signal coming from a transmitter even when there are a certain level of noise around the signal.


一.LTE CAT-M1 RF TEST(TS 36.521-1 )
1.transmit?
1.1 Maximum Power Output
1.1.1test requirement


1.1.2test condition
Test condition include Test environment setup,Test frequency setting?and Channel bandwidth setting
(1)Test environment setup

Mobile conformance testing can be categorized into 3 distinct areas:

- RF Conformance Testing.

- EMC Conformance Testing.

- Signalling Conformance Testing.

The test equipment shall use the same number of Tx antennas for all parts of the tests, Initial condition and Test procedure, as specified in the minimum requirement.

All test equipment shall provide (for the mode(s) supported) the following minimum functionality.

- The capability of emulating a single E-UTRA cell with the appropriate channels to allow the UE to register on the cell.

- The capability to allow the UE to set up an RRC connection with the system simulator, and to maintain the connection for the duration of the test.

(2)Test Frequency
(3)Channel Bandwidth

1.1.3test procedure


2.Receiver sensitivity

二.GSM RF test(TS 51.010-1 )
1.transmit
1.1Maximum power output
(1)requirement


2.receiver sentivity

總結
