TEST AND MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Determine Interference Problems With Narda’s IDA 2: Example GSM

    This application note discusses a case in which a continuous impairment in the GSM 900 band was affecting a cell phone station’s performance, and how Narda’s IDA 2 interference and direction analyzer was able to help.

  • LTE-A Base Station Receiver Tests

    This application note describes how all required receiver (Rx) tests (TS36.141 Chapter 7) can be performed quickly and easily by using vector signal generators from Rohde & Schwarz.

  • RF Testing On Automotive Infotainment Devices

    This application note highlights some of the RF measurement challenges and introduces Rohde & Schwarz equipment required for relevant RF characterization of car infotainment devices.

  • 802.11ad – WLAN at 60 GHz

    Data rates in the range of several Gigabit/s are needed to transmit signals like uncompressed video signals. Amendment 802.11ad to the WLAN standard defines the MAC and PHY layers for very high throughput (VHT) in the 60 GHz range. This white paper provides an introduction to the technology behind 802.11ad and highlights the test and measurement requirements.

  • RF Power Measurements In The Field

    Measuring RF power in a field environment can be accomplished accurately and inexpensively. It also involves a great deal of care and proper training to ensure equipment is accurately measured. Either way, accurate field power measurements will ensure transmitting equipment is operating properly.

TEST AND MEASUREMENT PRODUCTS

The MS46121B is a series of two PC-controlled 1-Port USB ShockLine Vector Network Analyzers with frequency ranges of 40 MHz to 4 GHz and 150 kHz to 6 GHz. The MS46121B provides performance and accuracy for your 1 port measurements in a low cost and space saving solution that is small enough to directly connect to the device under test. All the members of the MS46121B series are aimed at RF and microwave applications in manufacturing, engineering and education. The two MS46121B options both come with 120 microsecond per point sweep speeds and a measurement accuracy of +/- 0.5 dB (-6 dB offset, typical), making them suitable for your passive device test applications.

Cobham designs and manufactures PinPoint™ Shot/Sniper Detection Systems for military applications.
Dow-Key Microwave Corporation is pleased to present its new Matrix/PXI Catalog, which introduces the most popular, standard, and integrated switching solutions required in today’s broadband market -- everything from solid-state to electromechanical and reconfigurable PXI module switching systems.

Millitech’s millimeter wave phase locked synthesizers are ideal for use in test and instrumentation sources, as drivers for multipliers, as local oscillators for radar, radiometer, and telecommunications transmitters and receivers, and in PLDRO/YIG replacement applications. They feature low phase noise, ease of use, and a small size.

The MA24106A power sensor is a USB power sensor that eliminates the need of a traditional power meter. It is designed to provide accurate average power measurements from 10 MHz to 6 GHz over 60 dB of dynamic range. It is a highly accurate, standalone instrument that communicates with a PC via USB or with many of the Anritsu handheld products (often requiring Option 19). The power measurement capability of MA24106A is intended to mimic that of a traditional thermal (thermo-electric) power sensor by providing true-RMS measurements, although the MA24106A offers a wider measurement range. Therefore, it is ideal for measuring average power of CW, modulated RF waveforms such as 3G, 4G, OFDM, and multi-tone signals. True RMS power measurements enable one to make accurate measurements regardless of the input signal type.

Anritsu’s Mobile InterferenceHunter is a quick and reliable way to find multiple emitters, or single emitters even in difficult reception conditions. The ability to work with multiple signal sources, reflections, RF shadows, and multi-path distinguish the Mobile InterferenceHunter from conventional systems that depend solely on directional antennas. The ability to work with signals that are intermittent, bursty, or drift rapidly in frequency separate the Mobile InterferenceHunter from more expensive solutions targeted at a single fixed frequency interferer. The Mobile InterferenceHunter’s post-capture analysis capability allows users to modify search parameters without re-driving the route. This allows re-analysis of the captured data as well as consulting with experts.

Applications:

  • CATV Leakage location
  • Simplified Spectrum Clearing
  • Locating interference – Even in the presence of uplink signals
  • Finding pulsed or bursty signals

 Key Features:

  • Post-capture analysis
  • Sorts out signal reflections, shadowing, and multi-path
  • Quick setup in any vehicle
  • Much faster than conventional direction finding techniques

This spectrum analyzer is battery powered and compact, making it ideal for field engineers that don’t want to carry around a large and cumbersome bench-top unit. It covers the 5 MHz to 2,500 MHz frequency range and has a span width of 0-1300 MHz.

With its multi-channel 250 ps-resolution timing capabilities, Berkeley Nucleonics’ model 575 digital delay/pulse generator is ideal for laser experimentations involving triggering, gating, delaying, pulsing, or syncing. It can also be used in external clock syncing, laser induced breakdown spectroscopy (LIBS), PIV, laser timing, and more.
