Ventus 2.0 是一款使用 USB 2.0 的便攜式多標(biāo)準(zhǔn)信號發(fā)生器。它支持所有常見的地面廣播到衛(wèi)星信號。使用T-PUMP（隨附軟件）可以很容易地從一種調(diào)制切換到另一種調(diào)制。
Ventus 2.0 可以發(fā)出 30 MHz 至 2.5 GHz 的信號。
許多調(diào)制都可以播放。包括：ATSC、DVB-T/H、DVB-S2、DVB-T2、DVB-C、DTMB、DAB/DAB+/T-DMB、ISDB-T/B、開放式電纜、CMMB、ATSC MDTV、DAB+/DMB多路復(fù)用器。
基礎(chǔ)款Ventus 2.0 配備 -20dBm 的固定信號功率。通過添加衰減器，您可以將功率從-110dBm擴(kuò)展到+7dBm。
Ventus 2.0 采用無風(fēng)扇散熱設(shè)計(jì)。它具有出色的移動(dòng)性和緊湊的設(shè)計(jì)。
