全新GSG-2000系列是基礎型射頻信號產生器，提供9 kHz ~ 6 GHz 頻率範圍。產品適用於通訊教學與研究、射頻元件測試(如放大器、天線、濾波器等)、車用電子信號測試及IoT應用領域等，滿足射頻產品在生產/開發等階段的測試需求。相較於主要競爭對手，GSG-2000系列提供的優勢規格包含+20~-140 dBm寬廣的振幅輸出範圍，-117 dBc/Hz更低的相位雜訊；其頻率準確率規格為10 ppm頻率穩定度與2 ppm老化率，使用者亦可透過OCXO(Oven Controlled Crystal Oscillator)選配，讓頻率穩定度與老化率分別提升至10 ppb與0.1 ppm。
信號調變部分，全系列內建AM, FM, PM類比調變；GSG-2160則增加了數位信號調變功能，最高可達120MHz頻寬的數位信號輸出，支援ASK, PSK, APSK, QAM, FSK, MSK, User-define IQ, User-define FSK等調變信號。此外GSG-2000系列亦提供了LF信號與Pulse信號輸出，LF信號可供使用者輸出Sine, Square, Triangle/Ramp, Gaussian Noise信號；Pulse信號輸出則可模擬各種寬度的脈波應用；除了上述的信號輸出外，GSG-2000也提供AM/FM/數位IQ信號的輸入，以及數位I或Q信號獨立輸出埠。
GSG-2000使用七吋TFT LCD顯示器，可以完整呈現使用者所設定的參數與狀態；並提供USB, LAN, GPIB(選配)等通訊界面，並提供標準SCPI相容的指令支援遠端控制。GSG-2000專為3U標準機架尺寸設計。
GSG-2000 共有二個型號，主要差異如以下表格所示：
