This paper describes the design and implementation of the portable TT&C test equipment for small satellite. Now small satellites propose the idea of a quick test. For meeting requirement of the quick test, portable TT&C test equipment is proposed. The equipment takes full advantage of the current modular design technology, test bus technology, virtual instrument technology etc. It overcomes the disadvantage of traditional test equipment integrated difficulty, which is caused by traditional discrete and variety devices. The equipment has the advantages of scalable, flexible upgrade, compact, portable. After the experimental validation applied in the satellite test, it achieved good results. So it is important for test technological development of small satellite.
