ImmersionRC 射頻功率計 V2
ImmersionRC 射頻功率計 V2
FPV 的實現得益於兩條 RF 鏈路、一條控制鏈路和一條視訊鏈路。如果沒有射頻功率計,飛行員就無法測試這些關鍵的射頻鏈路。微波 (GHz) 連結的測試設備並不便宜。 ImmersionRC 幾年前改變了這一點,並向 FPV 社群提供了他們的「功率計 V1」。 V2 是聽取客戶回饋的結果。 ImmersionRC 增加了內部電池、內部衰減器以及每個 FPVer 所需的其他功能。
準確的射頻功率測量
最新的炒作 vTx 真的像數據表聲稱的那麼好嗎?它真的在所有比賽頻道上發出 25mW 的功率嗎? 30分鐘後它仍然發出25mW嗎?
RF 功率計 V2 可以回答這些問題以及更多問題。
早在 FPV 賽車的早期,ImmersionRC 就開創了低功率賽車的先河,每個人都運行 25mW。這在短短幾個月內就成為了世界標準,並且至今仍然是標準。功率計 V2 為您提供測試發射機所需 的測量工具 你會對下一場比賽感到驚訝。
非接觸式競賽合規性
您準備好在錘子出來之前測試您的視訊發射器了嗎?
憑藉隨附的短偶極子,RF 功率計 V2 可以滿足您在任何 FPV 平台上執行粗略功率測試所需的一切,甚至無需擰開天線。在「已知良好」的平台上校準儀表,然後沿著起跑線測試每個準備比賽的四輪驅動器。在第一扇門之前識別出意外設定為高功率(錘子就緒)的四邊形,或那些有硬體/電纜/連接器/天線問題且發射幾微瓦的四邊形。
我們稱之為「Scully 模式」是有充分理由的。 Joe Scully,業內最好的 FPV 主持人,完善了這項測試技術,以確保在全球四個角落的比賽取得成功。
功率示波器模式
所以您知道資料「資料包」正在從您的 R/C Tx 或遠端系統流向您的模型…但是如果您可以「看到」它們呢? RF 功率計 V2 的 PowerScope 模式為您提供無線電發射功率的可視化表示。它們發送資料包的速度有多快?您收音機上的眾多天線是否正常運作?他們在哪裡?什麼方向?您甚至可以發現符合 LBT(先聽後說)或占空比限制的發射機。 是的,它是一個極客工具,但它確實給異性留下了深刻的印象!
平均值和峰值測量
類比視訊發射器發出源源不絕的射頻訊號。遙控控制器發出一束脈衝良性流(剛好朝相反方向行進)。 RF 功率計 V2 可以為兩種類型的 RF 訊號提供準確的功率測量。
整合鋰離子電池
V2 包含整合式鋰離子電池,可為儀表供電至少 8 小時。閒置一段時間後會自動關閉,一次充電即可為您的儀表在賽道上供電數天。使用標準微型 USB 連接器可在一小時內完成充電。
