GL Communications Inc.
*The Voice Band Analyzer (VBA) is an analysis tool for monitoring the quality of voice band traffic (including hybrid echo) over VoIP, TDM and wireless networks*VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products, such as T1 and E1 Call Capture and Analysis, VoIP PacketScan&trade, and GSM, CDMA, and 3G Call Capture Products. VBA instantly detects voice file captures and with appropriately installed analysis modules, monitors speech levels, noise levels, and hybrid echo. Other analysis modules such as ITU-T P.561, P.562, P.563, fax and modem analysis, and many others can be hosted as plug-ins.*The VBA application can also operate on pre-captured files. It supports A-Law, µ-Law, 16-bit PCM (Intel), 16-bit PCM (Motorola) and MS Wave file formats.*Required software PKV100 and VBA032 at each probe location and PKV170 PacketScanWEB - Network Surveillance Software*Required hardware - 1U rack PC with sufficient hard disk for capturing over 10,000 calls (80 GB HD) for each VBA colocated with a probe*Additional hardware - PC for PKV100 PacketScan™ Software

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.

A comprehensive analysis of PV modules includes many different parameters. Determining the normal module operating temperature (NMOT), incidence angle effects and comparing soiling effects on different modules up to the initial degradation of PV modules are all parameters that can be analyzed with our outdoor exposure tester. The tester comes with up to twelve electronic loads installed in a 19" rack. The loads have two main functions: maximum power point tracking (MPPT) and IV curve tracing. For the advanced analysis, it is possible to change between these two modes within one test. In the normal operation mode, the electronic load keeps the module under MPP and each predefined interval an IV curve is traced. The entire tester comes with all necessary sensors such as temperature sensor, which can be attached to the module to determine the NMOT temperature like defined in IEC 61215 (MQT 05) and IEC 61853-2. The irradiation sensor is also included. In combination with our tracking system P2, it is also possible to determine incident angle effects of the PV module. It is also possible to connect other irradiation sensors for diffuse and direct irradiation, which helps to understand the behavior of the module in different irradiation conditions. An optional albedo meter is a powerful tool for the analysis of bifacial modules. The entire graphical user interface is web based and offers the possibility to access the system from the all computers in the network.
