Narrative:

First officer, myself, was descending from 15000 ft to 7000 ft. As I diverted my attention to change a frequency from stl VOR to runway 30R and as I looked up the captain was saying 7000 ft, 7000 ft. I disconnected the autoplt and climbed back to 7000 ft, from our lowest of 6600 ft. I feel my low time in type and the fact that I used to fly saab SF340 with an altitude capture function led to this deviation. Lesson learned: pay more attention to details.
