Power Function

TM 11-7010-201-40-1/ET821-AA-MMI-010/E154 MTS/TO 31S5-2TSQ73-2-1

a. Continuity Test. During a continuity test, the timing and control function applies a dc voltage to the CUT data

lines. Continuity test results are returned (through 72 data lines) to the probe control logic, which applies the probe data

signal to the error detect function or self-test function (during a self-test).

b. Functional Test. During a functional test, the reed switch control opens or closes the CUT reed switch under

control of the timing and control function. Test pattern data is applied to the CUT. The functional test results are

returned (through the 72 data lines) to the probe control logic. The probe control logic transfers the data to the error

detect logic for comparison with stored information. Either the GO or the NO-GO indicator is turned off by the timing and

control function according to the test results.

2-14. Power Function. Power to operate the MTS is provided by an external 135v power supply. The 135v input is

converted to 5v, 15v, +12v, +5v reserve, and +5v logic voltages by dc/dc converters PS1 and PS2. Power is

distributed within the MTS as shown in figure 2-9.
