The 1260-152 and the 1260-172 are high frequency coaxial switch
modules each containing 17 channels of SPDT (single-pole
double-throw) switches. The 1260-152 uses 50W coaxial cable and
the 1260-172 uses 75W coaxial cable. Otherwise, the two modules
are functionally equivalent.
The 1260-152/172 has two 26-pin front-panel connectors, labeled
J200 and J201. It is a 26-pin, MIL-DTL-28748 style, with shielded
coaxial pins. See Figure 2-1 for pin numbering. Table 2-1 shows
the mapping of channel numbers to connector pins. Information
about available mating connectors is provided immediately after
Table 2-1. See Figure 2-2 for a detail of the actual relay. See
Figure 2-3 for a block diagram of the 1260-152/172.
