Photo Emission Tech., Inc.
QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.

Signals & Systems India Private Limited
GPS Master Clock System – MCS-GPSMC-1010 is a 3U Card rack type, 19” Rack-mountable Redundant GPS Time Server which synchronizes and maintains the timing and frequency requirement of power and process industry equipment using a signal obtained from any one of the sources like GPS or GLONASS or Time protocols such as NTP and IRIG. It distributing the same time signal through several types of interfaces. It provides redundancy for Power and GPS receiver to increase reliability and offers protection against time synchronization failure. The system is field-upgradeable and an extremely flexible system, designed to handle time synchronization requirements today and in the future. It provides nanosecond accuracy when external time references are not available. It has a storage facility to store the system log file. It delivers NTP, SNTP, IRIG-B, PFC-Pulse, DCF77, BCD parallel data, Ethernet Fiber Optic & RS485/RS232 outputs. System enables configuration and monitoring through Web-based application. It supports a wide range of power supply either 90V-260V AC/DC or 18-36VDC or 36V-72VDC. Power supply model can be mixed and matched as required by the user, depending upon power supply options available at the installation site.

TA-100 -
Tech-Aid Products
The TA-100 signal generator was designed to facilitate testing of aircraft fuel flow indicators that require two input signals designated as “Drum” and “Impeller”. This generator provides both signals so as to provide a direct interface to the fuel flow indicator under test. The generator also provides switched power out to the unit under test as well as a 5v source for testing the bezel lighting. The original design was built around the requirements for the AMETEK series indicators (pn: 10171 series). This generator simulates a reference and a time delayed signal of appropriate amplitude for an indication of up to 1200pph for the indicator under test. The “PPH Select” switch provides fixed signal delays representing 0, 200, 400, 800, 1000 and 1200pph flow rates respectively, this provides the mechanic with an expedient check of the indicators accuracy. The “PPH Adjust” control allows the mechanic to vary the signal delay throughout the full range and serves as a good method for checking of pointer smoothness from stop to stop. The unit’s front panel also provides test jacks to monitor the “FDR Output” as well as the drum and impeller signals. The TA-100 requires only 28Vdc to operate. This generator provides a very economical approach to any repair facility or flight department as it becomes an alternative to purchasing two bench top signal generators. The TA-100 generator at the very least can provide a simple functional test and eliminate the high cost of exchanging an indicator as a function of troubleshooting the aircraft system.
