The Digital TGT Control Amplifier is a digital fit, form and functional replacement for the original Analog TGT amplifier of the MK-804, MK811 and MK871 engines of the Jaguar and Hawk aircraft. The Digital TGT Amplifier is a mature and field proven system.

The Speed and temperature(TGT) amplifier controls a solenoid valve in the fuelflow system. For a given throttle setting, the fuel-flow is controlled depending on defined external pressure and temperature conditions.

Pinaka has designed and developed a generic, CRI-certified microcontroller based "No Volts cum Pulse Tester" for fighter aircrafts that detects the presence of stray voltages. It also detects the correctness of amplitude and the duration of the firing pulses. The system is in operational use with ADA and HAL. This product of Pinaka demonstrate our ability to develop products in the realm of embedded hardware and software from design and development to testing and certification.

The DIN card takes discrete input signals, converts into data bits (1 or 0 according to the input logic level) and transfers to FPGA based I/O card. The FPGA I/O card is used as interface between IPC and DIN card. The host software receives the binary data from FPGA card and displays on GUI.

Single Board Computer(SBC) is a complete computer built on a single circuit board, with processor(s), memory, input/output (I/O) and other features like CPU i74790S, 8GB DDR3 RAM @ 1333MHz, 500GB SATA HDD, Graphics Controller Chipset Integrated Intel HD Graphics, Ethernet Interface 10/100/1000 Mbps, SBC Form Factor: - Full Size, Slot CPU Card.

The synchro card in ATE is capable of generating six outputs synchro signals and six reference channels (one used and five spare). The synchro output channels generated by ATE will be having a step size of at least 15. All the synchro channels will be routed through ATE control panel. Also, these will be available at patch panel for monitoring using synchro display. The synchro card generates synchro output signals on receiving commands from FPGA based I/O card. The FPGA I/O card is used as interface between IPC and synchro output card. The synchro card is capable of generating 3 phase synchro channels and single phase synchro reference signals. The angle set at GUI will be read by host software and send to FPGA card as commands. FPGA card sets the data bits (I/O bits) for generation of synchro outputs by synchro card.

The DOUT card generates discrete output signals on receiving commands from FPGA based I/O card. The FPGA I/O card is used as interface between IPC and DOUT card. The logic levels set at GUI will be read by host software and send to FPGA card as commands. FPGA card will be setting the data bits (I/O bits) for generation of discrete outputs by DAC card.

The DAC card generates analog output signals on receiving commands from FPGA based I/O card. The FPGA I/O card is used as interface between IPC and DAC card. The DAC card is capable of generating single ended voltages of both unipolar and bipolar types. The analog values will be set at GUI, which will be read by host software and will be sent to FPGA card as commands. FPGA card will be setting the data bits (I/O bits) for generation of analog outputs by DAC card.

The controller board is configured around Tiva TM4C123GH6PGE Microcontroller of Texas Instruments. The controller PCB consists of the microcontroller, two 16-bit ADCs, another microcontroller configured for implementing Ethernet MAC/PHY 10/100, Serial EEPROM and OLED Display. The controller board can be used as general purpose interface board for data acquisition using configurable interfaces such as Discrete I/Os, Analog Inputs, RS 232, RS 422/485, CAN, USB and Ethernet communication interfaces. Interface to SD card is also available for reading external data.
