[Milsurplus] CY-3690/SRM

[Nick England]

Used with AN/SRM-3 and AN/SRM-4 - in case you have a DASH helicopter
control system that needs testing....

The Test Set Target Control System AN/SRM-4 provides the facilities to test
the over-all
performance of the Target Control System AN/SRW-4B(DASH). The AN/SRM-4 test
set is capable
of receiving, decoding and displaying rotary wing drone aircraft commands
transmitted by the
AN/SRW-4B(DASH) system. By analyzing the test set front panel indications
resulting from
monitoring AN/SRW-4B(DASH)·system transmitted signals, system maintenance
personnel will be
able to isolate system malfunctions to one or more system components and/or
component parts
is possible when the AN/SRM-4 test set is used in conjunction with the
signal generating
capabilities of the Target Control System Test Set AN/SRM-6.
