COMPONENT TESTING

DLTS Measurements with Boonton Model 7200 Capacitance Meter

The Boonton Model 7200 Capacitance Meter is a precision, high-speed instrument used to measure the capacitance of semiconductor devices and passive components. One application for the Model 7200 is the measurement of Deep Level Transient Spectroscopy, or DLTS. This application note provides guidelines for using the Model 7200 in a DLTS system; it analyzes several ways of generating pulse bias and presents examples of the measurement capabilities of the Model 7200.

Automotive RF Immunity Testing using Peak Power Meters

The Boonton model 55006 USB Peak Power Sensor and 4542 benchtop Power meter used with model 57006 Peak Power sensor or model 51011 EMC power sensors are the instruments of choice for capturing, displaying and analyzing RF power for automotive EMC and RF immunity testing. This application paper focuses on discussing the usage of peak power meters in RF immunity testing for EMC purposes.

GaN or GaAs, TWT or Klystron - Testing High Power Amplifiers for RADAR Signals using Peak Power Meters

Measuring and characterizing pulsed RF signals used in radar applications present unique challenges. Unlike communication signals, pulsed radar signals are "on" for a short time followed by a long "off" period, during "on" time the system transmits anywhere from kilowatts to megawatts of power. The high power pulsing can stress the power amplifier (PA) in a number of ways both during the on/off transitions and during prolonged "on" periods. As new PA device technologies are introduced, latest one being GaN, the behavior of the amplifier needs to be thoroughly tested and evaluated. Given the time domain nature of the pulsed RF signal, the best way to observe the performance of the amplifier is through time domain signal analysis. This article explains why the peak power meter is a must have test instrument for characterizing the behavior of pulsed RF power amplifiers (PA) used in radar systems

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.
