  • Testing High Power GaN Amplifiers for Radar Signals using Peak Power Meters

    Gallium nitride (GaN) technology has become a staple for high power amplifiers (PAs) used in radar applications. Moreover, the high power and/or the radar application often require the signals to be pulsed.

  • Convert a Boonton 55 Series USB Sensor into an Ethernet-Connected Device by Using a Standard WiFi-USB Sharing Hub

    Boonton's 55 Series Wideband USB Peak Power sensor can easily be used for remote monitoring within your local network via a LAN (PoE - Power-over-Ethernet) or WiFi connection by using a standard WiFito- USB sharing device.

  • Peak Power Meters for Crest Factor and Scalar Measurements Using Broadband OFDM Signals

    In this application note we highlight how broadband LTE and WiFi power amplifier (PA) performance can be characterized using Boonton’s high performance USB peak power meter. Figure of merit measurements like input and output crest factor can be performed to characterize amplifier compression using highly dynamic and broadband LTE & WiFi signals. With the use of a directional coupler the USB peak power meter is transformed to make scalar-like measurements such as gain and return loss.

  • Boonton 4500B and the Trailing Edge Characteristic of a Pulse Power Measurement

    When demonstrating the Boonton 4500B to customers, a question often arises regarding the nature of the shape of the observed pulse when viewing in logarithmic mode. The trailing edge appears to display a slow decay, and there can be concern that the instrument is not showing a faithful reproduction of the pulse. The following article explains this phenomenon, which is present for all diode power sensors regardless of manufacturer, and shows that it has a negligible effect on measurement.

  • 4500B Advanced Trigger Capabilities

    Pulsed signals used for radar, remote sensing and tracking, MRI medical imaging, and certain wireless communication applications such as WiMax & LTE have become increasingly complex to measure. The instruments used to measure these signals must have sufficient capability to account for synchronization changes within a burst of pulses to capture a specific region and measure the signal accurately. A Peak power meter with advanced trigger capabilities is an excellent tool for this purpose.

  • 4500B Power Meter and the Built-In Precision Calibrator

    The Boonton 4500B power meter is the instrument of choice for capturing, displaying, analyzing and characterizing RF power in both the time and statistical domains.

  • Numerical Parameters Analysis of Boonton 4540 Peak Power Meter

    The Boonton 4540 series RF peak power meters consisting of the 1-channel 4541 and the 2-channel 4542 provide one of the most versatile power measuring systems with the capability of making over 20 different power related measurements on captured signals. The 4540 power meter can be operated with Boonton peak, CW power sensors, and voltage probes and can function as a CW and Peak power meter, statistical power analyzer and RF voltmeter. The instrument provides three basic power measurements – pulse power, modulated power and statistical power. Each mode is targeted towards a specific type of measurement which can be displayed both graphically and numerically.

  • 4500B Digital Sampling Power Analyzer for Wireless Communication Signals

    Digital modulation methods of cellular and other wireless communications system present a challenge for making accurate peak power measurements. Although there are many different implementations, the Orthogonal Frequency Division Multiplexing (OFDM) and Spread Spectrum Modulation are the latest technologies. Of many wireless communication systems, WCDMA (Wideband Code Division Multiple Access) is the one which uses several modulation schemes.
