Versatile Digital Signal Level Meter

Sunday, September 25th, 2011

Toronto, Canada – GAO Instruments has rolled out its digital signal level meter which is designed to provide users with optimal functions at a good price point. It is specially intended for use in the maintenance of digital, analog, digital FM, dual channel measurement or bilateral networks. Featuring a durable and portable design, easy keypad operation, high accuracy and quick response time, it is an ideal tool for field technicians.

This handheld digital signal level meter, model A0N00009, operates over a frequency range of 5 to 870 MHz. It measures analog and digital channel power as well as quality measurements such as difference-carrying, MER (modulation error ratio), BER (bit error rate) and signal-to-noise ratio (SNR, S/N). This portable digital signal level meter performs auto channel spectrum scanning, limit testing and auto testing and also has functions such as single and multi-channel testing, and all-band scanning.

It allows direct entry of a channel or frequency and offers great flexibility in head-ends and distribution networks that employ narrow digital signals or non-standard frequency applications. This digital signal level meter boasts a bandwidth of 0.28 to 9.99 MHz and a signal level measurement range of 30 to 120 dBμV at a precision level of ±1.5 dB. It is able to analyze QAM 32 64 128/ITU-TJ.83 Annex A/B/C modulated signals and provides a spectrum analysis span of 6.25, 12.5, 25 and 62.5 MHz. It uses an RS232 interface or a USB port for data exchange. In addition, PC toolbox software and constellation diagram display are provided.

This easy-to-use digital signal level meter belongs to GAO’s family of CATV Meters & Instruments. This line of products includes CATV analyzers, digital signal level meters, PCM Channel Analyzers, Handheld Signal Level Analyzers and Handheld CATV/QAM Analyzer which features main functions of CATV, QAM and cable modem measurement.

Toronto, Canada – GAO Instruments has launched its handheld network tester designed for the IP end user. It is a complete tool for cable installation and network maintenance.

This full-featured network tester, model A0060002, integrates the functionality of both a Time Domain Reflectometer (TDR) and a Digital Multi- Meter (DMM) into one unit. It is designed for network layer testing including Ping, IPconfig, Tracert and Route, cable length testing, PPPOE dialing, attribute revision, and the performance of DMM tests and wiring diagram testing to validate cable link sequence.

The network tester performs DMM tests such as AC or DC voltage, loop resistance, line capacitance and line insulation.  It tests 4 pairs of non-shielded cables and 4 pairs of shielded cables including CAT5, CAT5E and CAT6. It can also test the cable length and locate breaks or and faults within a maximum distance of 150 m.

This handheld network tester offers fixative IP scanning and Web browsing for LAN test and has a memory capacity of 20 M to store test results. It can be powered by a rechargeable Li-ion battery or a 9.6 V DC adaptor. In addition, the embedded software can be upgraded to the latest version through LAN or USB.

This full-featured network tester belongs to GAO’s family of Network Testers. This line is suited for the installation and maintenance of networks and conducts network testing, cable testing and many other tests. The line includes Network Tester and Handheld Portable Gigabit Ethernet Tester which is an ideal tool for the front-line field workers to analyze the network quality and locate the fault rapidly.

Handheld Fiber Optic OTDR for Telecommunication Networks

Monday, September 12th, 2011

Toronto, Canada – GAO Instruments has announced the launch of its handheld fiber optic OTDR for telecommunication networks. It is an innovative test instrument specially designed for fiber network construction and maintenance in FTTx, WAN and CATV systems.

This handheld fiber optic OTDR, model C0250001, features a compact size, easy operation, high dynamic range and high precise measurement. It is complete with adaptors for connection to different fiber types. It is also resistant to dust, moisture and shock, which allows it to perform well even in harsh environments.

This fiber optic OTDR performs testing in average and real time modes. It can be used in both single mode and multi mode fiber applications. It provides a wavelength of 1310/1550 nm ± 20 nm for single mode fiber and 850/1300 nm ± 20 nm for multi mode fiber. The event dead zone for single mode fiber is only 3 m and for multi mode fiber is 7 m.

The unique hot key design makes it convenient and quick to conduct, review and analyze test results. It has a large memory capacity to save up to 300 test curves and can transfer them to a computer via RS-232 or USB port for further analysis, reporting and printing via included software. In addition, it is powered by Ni-MH rechargeable battery or AC adapter for over 3.5  hours of continuous testing operation on a single charge.

This fiber optic OTDR belongs to GAO’s family of OTDRs. Another product in this line is multi-function optical time domain reflectometer which can be used for testing in a variety of fiber optic applications including WDM, MAN, FTTH and LAN network. This line of OTDRs is important test equipment used in fiber optic work. They are widely applied in the manufacture, construction and maintenance of optical fibers.
