關于BT Dongle的一些困惑.
来源: 评论:0 点击:
我們這邊由于大量生產,測試V BT Throughput就直接用Dongle和机台進行聯系.在沒有attenuator的情況下進行測試,這樣測是否可以通過將天線的長度縮短,來确定一個最佳測試位置,??這樣就可以省下attenuatorle
因為在用attenuator的Dongle站上,机台的測試位置對Throughput也有很大影響.attenuator還可以在門限直偏离5個DB進行測試.

BT dongle is class 1 product, so if you see even 5dB difference between products, it is normal.
If you don't use an attenuator to test the BT dongle, then the transmitter power can't be adjusted properly, as Dongle is not the same as a headset.
Dongle has power adjustment according to RSSI, the transmitter power has to be adjusted according to different receiver position. While headset(class2) is always working at the maximum transimtter power.
