AVHRR/3 is a six channel imaging radiometer that detects energy in the visible IR portions of the electromagnetic spectrum.
HIRS/4 provides multispectral data from one visible channel, seven shortwave channels, and twelve longwave channels using a single telescope and a rotating filter wheel containing twenty individual spectral filters. AMSU-A is a cross-track scanning total power radiometer, which is divided into two physically separate modules that interface with the spacecraft independently. The AMSU-A measures scene radiance in the microwave spectrum. MHS is a five-channel microwave instrument intended primarily to measure profiles of atmospheric humidity.
