USER SOLUTION - Joint-less track circuit portable test set

The portable test set purpose is to perform a simple test (go/ no go) for the the testing of Transmitter, Receiver and Code generator modules. The tests are limited to testing the primary functionality of the modules only.

There are five unit types across two series types, the 2500 and the 2550, two transmitters one from each series, two receivers one from each series, and one code generator.
 
A dedicated hardware interface is used for each module type when tested which is built into the Test Set. The Test Set includes the software to test each type, guiding the operator to perform any specific actions. The operator selects the module type to be tested and is guided to enter the correct part number through a pull down list to load the correct test set software.
 
Only one type of unit is tested at any one time. The receiver module test requires the simulation of the transmittal tones for the test to perform correctly, where as the transmitter and code generator test requires the output signals to be analysed.
