National Instruments MCX-SMB Coaxial Cable

The MCX-SMB Coaxial Cable (Part Numbers: 188376-01, 188376-2R23, and 188376-0R3) is a general-purpose, Coaxial Cable from National Instruments. This type of cable is offered with a 1-Pin, Female SMB Back-End Connection and a 1-Pin, Male MCX Front-End Connection. The National Instruments MCX-SMB Coaxial Cable is widely used in the construction of test and measurement systems containing RF signal generators and other devices with RF interfaces. This cable is available in 0.3 m, 1 m, and 2.23 m lengths.

It is important to note that a long cable can pick up extra noise just like an antenna. Thus, you are supposed to select the right length cable according to your test system requirements. The NI MCX-SMB Coaxial Cable has an impedance of 50 ohms. It should only be considered for test systems where impedance remains around 50 ohms. Matched impedance can limit the signal reflection and increase the maximum power transfer through your system.
