Rode NT1 Signature Mic White Noise

I'm new to the XLR family so please bear with me. I'm using a Rode NT1 Signature Series Microphone, Behringer UMC22 Interface, and Audacity. Everything is connected properly; no loose connections or cables. My phantom power is on. However, I'm getting a lot of static white noise and some weird warbling sounds in the background of my audio (mind you, I'm in a completely silent, noise-treated space). This background noise is at a consistent volume even with the gain all the way down. Please help!
