  We give a characterization of the two-weight inequality for a simple
vector-valued operator. Special cases of our result have been considered before
in the form of the weighted Carleson embedding theorem, the dyadic positive
operators of Nazarov, Treil, and Volberg in the square integrable case, and
Lacey, Sawyer, Uriarte-Tuero in the L^p case. The main technique of this paper
is a Sawyer-style argument and the characterization is for 1 < p < \infty. We
are unaware of instances where this operator has been given attention in the
two-weight setting before.
