A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

Some of the electrical signals we work with are said to be “floating” with respect to ground. A typical example might be a voltage drop over a shunt resistor in a power supply or a complex biomedical ...

The FFT from the amplifier output is nice and clean with 2 nd harmonic down -109dB below the fundamental when driven with 2Vrms on the analog inputs. Curious when the same test was repeated with a ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

Marantz Amp 10 Power Measurement Table * Marantz does not recommend bridging the Amp 10 when driving 4-ohm speakers. The amp could current limit and potentially shut down at max power, which is what ...
