October 4, 2022 - Vista, California - Axiom Test Equipment, Inc., an electronic test equipment rental and sales company has published a new blog post entitled, "Teaming Amplifiers and Signal Generators," that explains how connecting a suitable amplifier to a signal generator can be boosted to the power levels needed in a project. Signal generators serve as sources of analog, digital, and even RF/microwave signals for test purposes. They may not always deliver enough output power for some tests, such as characterizing filters and antennas, and help may be needed. By connecting a suitable amplifier, a signal generator can be boosted to the required power levels. Finding the right combination comes down to knowing the key specifications for both units.

Laboratory amplifiers can be specified by frequency range, bandwidth, output power, and gain or input power required to reach the rated output power. A compatible signal generator must provide sufficient input power to drive a test amplifier to its rated output-power levels with minimum noise and distortion. The output of a signal generator may be adjustable over a certain power range by means of a manual control on the unit or remote computer control, such as GPIB or RS-232.

Selecting an amplifier and signal generator will be narrowed down by the type of testing performed on the DUT. Specifically, it will determine the signal power levels required, with the highest power levels typically possible for the shortest pulses, as in radar component and system testing. Learn more information about amplifiers and signal generators by reading the full post on Axiom's website.

Teaming Amplifiers and Signal Generators

Signal generators serve as sources of analog, digital, and even RF/microwave signals for test purposes. They may not always deliver enough output power for some tests, such as characterizing filters and antennas, and help may be needed. By connecting a suitable amplifier, a signal generator can be boosted to the power levels needed. Finding the right combination comes down to knowing the key specifications for both units.

Laboratory amplifiers can be specified by frequency range, bandwidth, output power, and gain or input power required to reach the rated output power. Amplifiers may be suited for a variety of signal types including pulsed signals and with different forms of modulation, such as amplitude modulation (AM) and frequency modulation (FM). Understanding the measurement requirements for the signals applied to a device under test (DUT), such as phase noise, harmonics, and spurious levels can help establish minimum requirements for a test signal generator as well as the amplifier that will boost it.

To minimize noise, an amplifier and signal generator should be impedance matched. Most high-frequency test equipment is designed at an impedance of 50 ?, although some equipment for video testing may be at 75 ?. Interconnections are usually by means of coaxial connectors with Type N connectors, for example, operating to about 10 GHz and 100 W. They are available in 50- and 75-? versions and used in both amplifiers and signal generators, with SMA and other connector types serving higher frequencies...
