USG 系列
| 特點： |
| - 頻率範圍: 34.5MHz ~ 4400MHz - 功率輸出範圍: -30dBm ~ 0dBm - 連續波無任何調變信號 - 支援固定頻率、單次掃描、連續掃描、跳貧及功率掃描模式 - -107dBc/Hz 相位雜訊 @100kHz 位移點 - 頻率解析度: 10kHz - 電腦USB介面供電與控制 - 外部程式支援不同的作業系統 |
产品叙述：
- 固緯電子推出新的USG系列RF信號產生器，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信號產生器，其輸出頻率範圍從35MHz 至 4400MHz；USG系列僅提供連續波(CW)信號 輸出，無任何信號調變功能。USG 系列RF信號產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波、頻率掃描、跳頻及功率掃描、有頻段限 制USG系列的信號產生器提供比較低的諧波harmonic輸出性能。
