Case1. B7 + WLAN 2.4G
7
以前找IM3 2f2 - f1都要key 一堆channel, 然後EXCEL找
現在不用, 只要一鍵
8
1.
2.
3.
WiFi 2.4G有1-14個channel, 輸入w1……w14 or
9
2.
一個一個 channel設太麻煩, 你也可以直接輸入 wifi_2.4G
10
Case2. B4 + WLAN 5G
11
同理 WLAN 5G 124 channel or
1.
2.
12
一個一個 channel設太麻煩, 你也可以直接輸入 wifi_5G

13
Case3. B13 + BC0
14
Case4. B25 + B4
15
你以為只有降嗎XD
往下拉
16
Case4. B25 + B4
一鍵分析 GNSS(GPS + Glonass + BeiDou + Galileo) Rx 被哪兩個Tx IM3攻擊到
17
Case5. SVLTE mode
遇到Dual Transmissions in AWS and PCS Bands攻擊GPS也找的到
18
Case5. SVLTE mode
遇到Dual Transmissions in AWS and PCS Bands攻擊GPS也找的到

Case6. 最常見的GPS and B13
20
除了IM3, 他兄弟IM2當然也要把他找出來
Case7. SVLTE mode, 1x BC0 and LTE B4 IM2
21
Case8. GNSS被WiFi 2.4G and B26 IM2打到
外加26 Rx被WiFi 2.4G and B26 IM3打到
再來WiFi 2.4G Rx被B26 3rd harmonic打到
22
Case8. GNSS被WiFi 2.4G and B26
IM2打到
外加26 Rx被WiFi 2.4G and B26
IM3打到
再來WiFi 2.4G Rx被B26 3rd
harmonic打到
23
Case9. QTI 80-N5420-19 B20 IM3 case 也來測試一下!!

Case9. QTI 80-N5420-19
B20 IM3 case 也來測試
一下!!
25
你是不是有點愛上我XD
不是~
是愛上這套一鍵版的 Band Allocation Overlap and IM2 IM3 Freq Calculator 了呢
26
最後~
還是老話一句
盡量使用
謝謝支持
有問題 feedback to me
