固緯電子推出*新的USG系列RF信號產(chǎn)生器，有5種型號可以選擇。USG系列是輕巧攜帶型及USB介面相容的RF信號產(chǎn)生器，其輸出頻率範圍從35MHz 至 4400MHz；USG系列僅提供連續(xù)波(CW)信號輸出，無任何信號調變功能。USG 系列RF信號產(chǎn)生器內建電子衰減器，可以調整功率範圍從-30dBm至 0dBm。USG系列提供幾種不同的操作模式如單點連續(xù)波、頻率掃描、跳頻及功率掃描、有頻段限制USG系列的信號產(chǎn)生器提供比較低的諧波harmonic輸出性能。
圖示為同時進行功率掃描及頻率掃描USG-LF44的測試結果，此測試結果的頻率範圍從35MHz至4400MHz及功率範圍從-30dBm至0dBm。黃色記錄線為記錄峰值的測試結果。粉紅色記錄線為掃描中的輸出信號的測試結果。
