Toronto, Canada – GAO Instruments has released an arbitrary waveform generator and frequency counter which boasts DDS circuit to produce the corresponding DAC refreshing clock. It directly reads waveform data files produced by Tektronix oscilloscopes or Tektronix waveform editor software and displays the waveform. The waveform generator uses DDS technology so that it has advantages of high frequency accuracy, high waveform resolution, high reliability and wide software support.

This cost-effective USB waveform generator and frequency counter, model A0200002, is shipped with both SDK and API and can be easily integrated or embedded into other auto-measuring systems. It is integrated with one channel of arbitrary waveform output, 8 bit output, synchronized signal output and two input channels for counter/frequency measurement, 8 bit input and external trigger input. Users can arbitrarily edit the waveform using a mouse. Parameters such as amplitude, frequency and offset are configurable. Users can also choose regular waveforms including Sine, Square, Triangle, Saw-tooth, TTL, white Noise, GaussIian Noise, Trapezoid, Exponent, AM and FM are configurable. A computer transfers the waveform data into the memory of the signal generator via USB bus; the ID counter cycles and sends the periodic waveform data to the DAC circuits.

Its price has been reduced to US$459.00 for a limited time only.

Toronto, Canada – GAO Instruments has released a digital insulation resistance tester which accurately measures insulation integrity on electric equipment such as transformers, electro-motors, cables, switches and other wiring. The intelligent digital device predicts, prevents and identifies insulation failures that may cause appliance failure, stop production and create power problems or even put lives at risk. Due to its multiple test voltages, this digital insulation resistance tester is ideally suited for such applications as troubleshooting, commissioning and preventative maintenance.

This practical digital insulation resistance tester, model A0300029, includes a built-in high power voltage generator that enables the output testing voltage to be adjustable over 250V, 500V or 1000V depending on requirements. It tests insulation resistance up to 2000MΩ and measures alternating current and voltage below 750V AC. A high contrast backlit LCD screen allows for visibility of test results under bright sunlight or in poorly lit environments. Encapsulated in a rugged and moulded plastic case, this high performance digital insulation resistance tester is an invaluable tool for field testing.

Toronto, Canada – GAO Instruments has released a CPU-controlled Radio Frequency (RF) signal generator operating over a frequency range from 300kHz to 300MHz. It is an ideal tool for research, development and production testing of AM/FM receivers, civil-band transceivers, radio remote-controlled devices such as toys and wireless telephones. The RF signal generator offers a frequency synthesizer to enable the output signal to be determined very accurately and frequencies to be entered directly from a keypad or via remote control. The high accurate RF signal generator, model A0400001, provides AM and FM modulation types and supports the output levels varied in 0.1dB step. With optional RS-232 and IEEE-488 (GPIB) interfaces, the generator can be formed into an automatic test system under the control of a host computer combined with other instruments.

Toronto, Canada – GAO Instruments has released its fiber optic identifier which is suitable for use in test labs and. is an essential tool for the installation and maintenance of telecommunication and CATV systems. The identifier detects signal frequency tones of 270Hz, 1kHz and 2kHz. It efficiently and accurately identifies the traffic direction and frequency tone of an optical fiber and indicates status through LEDs.

This high performance optical fiber identifier, model A0640002, features low bending loss, provides an easy-to-replace adaptor and displays three levels of signal intensity. It identifies optical signals at wavelengths from 900 to 1650nm. This compact fiber optic identifier does not require opening a fiber at a splice point for identification and thus avoids interrupting service. In addition, an audible tone can be heard when destructive detection is present on the fiber during testing.
