1. A computer-implemented method for performing transmitter equalization for a host device comprising one or more ports, each port comprising at least one channel, the computer-implemented method comprising:
capturing a single output signal transmitted from the port on the at least one channel;
determining an impulse response of the channel, based at least in part on the single output signal;
generating a transmitter feedforward equalization (FFE), based at least in part on the impulse response of the channel;
determining a reference receiver configuration associated with the transmitter FFE from a plurality of reference receiver configurations specified in a standard; and
applying the transmitter FFE to the channel of the port of the host device.
