- They consist of one or two Model 71690 XMC modules mounted on a cPCI carrier board
- Model 72690 is a 6U cPCI board while the Model 73690 is a 3U cPCI board; both are equipped with one Model 71690 XMC
- Model 74690 is a 6U cPCI board with two XMC modules rather than one
- These models include one or two L-Band RF tuners, two or four A/Ds and four or eight banks of memory.
