  • Low Cost, Wide Bandwidth Microstrip Signal Switching System for ATE Applications

    Publication Year: 1983, Page(s):21 - 23
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (264 KB)

    ATE signal switching systems are subject to ever wider signal switching bandwidths and higher levels of adjecent channel isolation requirements. With the MATE Guidelines, the specified channel-to-channel isolation at the ATE Interface has been set to 50 dB at 300 MHz. Present methods to realize these bandwidth and isolation requirements in ATE station switching systems often include the use of coa... View full abstract»

    The last few years have seen a rapid increase in the use of computers to measure and evaluate microwave data. To assist in these tasks, many individuals have developed various formats for storing microwave data in mass memory, for example, magnetic tape or disc. The formats generally vary from person to person, program to program and computer to computer. In this paper we shall distuss whether the... View full abstract»

    Narrow band YIG tuned filters are ideal for filtering out harmonics, spurious responses, and other unwanted signals from signal sources such as sweepers and synthesizers. They are also extremely useful in ATE used for spectrum analysis and receiver testing. Unfortunately various tuning errors make it difficult to accurately track these devices to the desired signal. Readjustment is needed whenever... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (844 KB)

    The Radio Spectrum Measurement System (RSMS) has been used by the U.S. Department of Commerce since 1973 for gathering frequency usage data for purposes of frequency management. The HP 8580 automatic spectrum analyzer used in this mobile system is now being replaced with a more modern system. The new system will provide measurements over the 0.01-18 GHz range with bandwidths of 10 HZ to 30 MHZ. A ... View full abstract»

    The coaxial "Tee" junction was studied with one arm first open, then shorted to form stubs. This same arm was then terminated to complete this investigation. The equivalent parameters at the "Tee" junction were extracted using time-domain techniques. The excitation of the "Tee" from both the stem and side ports were experimentally performed.

    A number of Important measurement applications will currently produce errors when using standard hardware and software, This is primarily because the software model of the calibration standards overlooks some hardware features. In most cases, a minor modification of the software, or of it's use, will solve the problem. The applications will generally apply to the HP8409 and HP8542 VANA systems. View full abstract»

    Power at microwave frequencies is expensive.The higher the power, tbe higher the price. For exaaple, the typical price of a one watt amplifier at x-band is in the neighborhood of 5%. But a two watt amplifier can cost as much as 501 times more than its one watt counterpart. Double the frequency and the price can albo easily double. Vendors want to ensure that their products are meeting their power ... View full abstract»
