RELATION TO SIMILAR EQUIPMENT
Radio T-b29
The AN/TPS-31 is designed for operation with Standard Navy
Trigger Input: 20 to 40v peak, across 75 ohms pos, at
Repeaters such as the VJ-1, VK-1, AN/SPA-4A, AN/SPA-BA, and
1000 or 41000 pps, from unit 2A2
AN/ SPA-34A. These repeaters can be used as substitutes for the
Video Input: 0.5 to 1.Sv, limited, pos across 75 ohms
remote harbor-control site, in parallel with the remote site, or as a
from unit 2A2
substitute at the remote harbor-control site.
