Sony PXW FS7 frame rates

Sony overview claims 120fps and 180fps for some formats shot by the PXW FS7. Yet their specs page pro.sony.com/bbsc/ssr/product-PXWFS7/ shows frame rates no higher that 59.94p and something they call 59.94i. What's the truth here? Any one know? Are they interlace recording at 59.94 and doubling the fields to get their 120 and 180 frame rates? Or is it actually 59.94 interlaced, which I saw for the first time recently. A truly awful thing to watch btw.

Any insight into what this camera is doing would be much appreciated. Thanks.

I'm pretty sure it does 4K internally up to 60fps and HD up to 180fps. By using an Odyssey 7Q and the extension back (forget what it's called) you can go up to 240fps HD/2K.

Thanks very much.
