amplifiers

Voltage Standing Wave Ratio results from an impedance mismatch between a source (an amplifier) and a load (test application). This mismatch can influence the performance of the source.

To avoid costly errors in selection, invest the time upfront to gain a basic yet thorough grasp of key amplifier specifications and operating principles before identifying the optimal model for your application needs.

The testing of automotive electronic systems requires a sophisticated highspeed 4-quadrant amplifier. Many EMC...

This article describes a loss-less impedance matching technique that does not require the use of discrete components but instead uses cables or printed circuit board (PCB) traces, i.e., distributed elements or transmission lines.

Ever tried to measure low-level signals in the presence of noise? Or wanted to capture a measurement isolated from ground, like that of an ungrounded hand-held digital multi-meter, but also needed to capture finer details of the signal, like those captured with an oscilloscope?

More power costs more money when it comes to broadband power amplifiers, so we typically only specify/buy to meet our current needs rather than what we may need in the future.

A preamplifier (preamp) is a low-noise, high-gain amplifying device that plays an important role in performing electromagnetic compatibility (EMC) radiated and conducted emissions testing. 

This brief article is geared towards EMC test practitioners who are tasked with specifying broadband RF amplifiers for RF immunity testing and need to quickly get up-to-speed on the key factors involved in the buying decision before actually making the purchase of an expensive amplifier.
