量測低頻 RFID 標籤的特性使用 Keysight N9322C 基礎頻譜分析儀(BSA) 摘要無線射頻識別(RFID)標籤的共振頻率是決定標籤和讀取器之間有效通訊距離的關鍵因素。藉由使用 Agilent N9322C 基礎頻譜分析儀(BSA),您可輕而易舉地量測 RFID 標籤的共振頻率。 RFID 標籤簡介RFID 標籤是一種結合無線接收器和發射器的小型轉發器,同時也是無線射頻識別(RFID)系統的關鍵元件,負責在短距離內傳送身份識別資訊。一般而言,RFID 標籤包含兩個部分,一部分是積體電路,用來儲存和處理資訊,並且調變和解調變 RF 信號。另一部分是天線,用來接收信號並發送到讀取器(參見圖 1)。RFID 標籤的共振頻率是影響讀取器和 RFID 標籤之間有效通訊距離的關鍵因素之一。工程師可用非接觸式耦合方法量測封裝後之 RFID 標籤的共振頻率。該頻率會反應回返損耗特性曲線的負峰值。  N9322C 是通用的射頻分析儀,可提供頻譜分析、傳輸量測,以及反射量測等擴充功能。此外,只要添加信號追蹤產生器(選項 TG7)和反射量測應用軟體(選項 RM7),N9322C BSA 還可以測試 RFID 標籤的回返損耗特性:• 選項 TG7 信號追蹤產生器包含一個內建的 VSWR 電橋,讓您能輕鬆使用 N9322C BSA 執行反射量測。相較之下,其他分析儀需使用外部電橋才能進行相同的量測。• 另外,N9322C 的反射量測模式採用精密的開路 - 短路 - 負載(OSL)校驗程序,大大減少了系統誤差。   N9322C 基礎頻譜分析儀(BSA)是經濟有效的通用型射頻分析儀,除了提供通用的頻譜分析功能外,還提供單埠向量網路分析,以及選配的信號追蹤產生器和內建的 VSWR 電橋。在 RFID 設計過程中,您可使用...

4416A 射频录制仪

 

 

This device can record RF signals in various points of fields. When reproducing the signal data in factories or laboratories, it is possible to test receivers under the reception environment of the data.

 

Features:

 

- Compact size and all-in-one model.(Weight:Approx.8 kg)

- This device adapts to DC +12 V input.

- The frequency range covers 30MHz to 1002MHz of the recording frequency.

- 8 MHz bandwidth RF signal can be recorded/reproduced. In addition, when using the option, 24MHz bandwidth and 40MHz bandwidth RF signal can be recorded/reproduced.

- 7-inch wide type VGA touch panel is equipped.

- When using the spectrum display function , the spectrum at the recording can be confirmed.

- The solid-state-drive (SSD) for the data recorder is equipped as the standard. (Data of 90 minutes can be recorded/reproduced at 8 MHz bandwidth signal captured.)

- Data can be backed up at high speed through eSATA port and USB2.0 port.

- The Low Noise Amplifier is equipped to the RF input side.(NF=2dB typ. At -80 dB signal input)

- Auto Cal function that sets the level of the recorded signal automatically at the RF signal capturing is equipped. • Time recording function and repeat reproduction function are equipped.

- It corresponds to RF record and reproduction under diversity environment by using two or more sets.

- The frequency and level at the recording can set automatically at the reproduction .

- Data in ATSCA-74 standard can be reproduced.

- Remote control is possible.

 

- 8/24/40 MHz bandwidth RF signal can be recorded/reproduced

- 30MHz to 1002MHz frequency range
