The display is described as "4.3" Color TFT WQVGA (480x272) with LED backlight" so not OLED.
The 16-bit DACs are nice, too. There are all sorts of other goodies, like variable bandwidth (pseudo-random) noise that can be used to modulate or add to an output. I've hardly started to explore it yet. This is an upgrade from an HP 33120A which was the first ever model of ARB I used, many years ago, to simulate a pulse-output transducer.
I now have a collection of 33522B, 33120A, 3312A, & 3311A generators...
