Selecting an antenna for testing can sometimes be straightforward but often requires some specific consideration. This application note offers several simple guidelines for choosing the best antenna for your application.
Almost every RF test setup requires connectors and cables. Connectors will influence test results in various and sometimes unpredictable ways. Test equipment can compensate for some of these influences but often with detrimental effects. This article discusses how the connections used in a test setup will affect test results and why it is important to create a valid test environment.
Antenna beamwidth determines the expected signal strength given the direction and radiation distance of an antenna. This white paper presents a better understanding of beamwidth and how it influences a test environment is critical to accurate and repeatable tests.
This article describes a test procedure where the small signal performance data of an amplifier is gathered and checked against previously recorded data. This is a fault-finding step that establishes the health of the preamplifier.
For many years most regulatory standards called for the use of a half-wave dipole antenna set for frequencies above 20 MHz. However, to reduce test time, broadband antennas such as the biconical antennas began to be accepted.
In recent years, the use of a term call "Antenna Factor" in EMC and spectrum pollution work has become very important. There has been a great need for measuring field intensity and/or power density as accurately and conveniently as possible.
A.H. Systems provides many models of portable antenna kits from 20 Hz to 40 GHz. Each kit contains all the necessary antennas, current probes, and cables. Each antenna is individually calibrated and all is contained in a rugged carrying case.
Engineers performing RF enclosure, emissions, or field testing frequently will need to use a preamp with their receiver and associated antenna. Some best practices can improve results and avoid problems.
