  4. 4. 4 Description: Automatic Test Equipment (ATE) for TARANG (Radar warning receiver) in Fighter Aircrafts. ATE is a Universal tester to carry out the Analog, Digital and RF tests for various LRU’s of TARANG System. Interface Module routes all required signals to tests LRU. It Consists of Current Measurement Card, Relay Driver Card and Interface Card. Programmable Voltage Generator (0-60VDC) This card is used to generate Programmable voltage (0-60VDC), which is required to test LRU and it is capable of generating the different voltage for its internal operations This card communicates with PC through RS232 gets the commands and generates voltage output voltage accordingly. All the signals are generated and controlled by 8-bit Micro controller and read back the Voltage through TLC548. Current Measurement Card This card is used to measure the Current consumed & Voltages from the LRU through the Multi Output Power Supply of ATE using current monitoring circuit.  PROJECT Project name : Board Test Adapter (BTA) Team size & Role : 6, Team member (Design, Development, Testing) Description : BTA is used for testing PCBs of different LRU’s of RWR system. The BTA communicates with PC through USB communication. BTA facilitates troubleshooting the cards down to fault signal flow path and in some cases to specific faulty component. Digital Input Output (DIO) card Digital input and output board is an ISA based one, which is used to generate all the discrete TTL signals required by the LRU’s of Tarang RWR System. This board can generate 48channels of TTL signals by using PPI (82C55), 12 Pulse IN & 12 Pulse OUT channels. Two numbers of PPI’s are present in this board and each can generate 24 channels of TTL signals. All the control signals for the PPI are generated by the EPLD present in the same board. This board also generates TTL pulses and driven by Pin drivers (EL7156) PERSONAL PROFILE: Nationality : Indian Father’s Name : R.K.Kumaresan D.O.B : 08.06.1984 Language Known : English, Tamil Present Address : #600,4th A main, 13th cross, Virat nagar, Bommanahalli, Bangalore – 560068 Passport No. & Expiry date : N2415066, 19.08.2025 Declaration: I declare that the information given above is true to the best of my knowledge and belief.
