Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

In certain applications, like pH measurement based on electromagnetic field (EMF) changes in an electrochemical reaction, the change in voltage is very small and the voltage range varies with the ...

value output is carried out via a USB connection, which also serves as a power supply. In addition, the wavelength information is available as voltages of up to 4.096V at the analogue output. The ...

Researchers at the National Institute of Standards and Technology (NIST) have invented a miniature thermometer that could be used to monitor the cryogenic temperatures of processor chips in ...

Some applications require the production of multiple clocks with a synchronous, adjustable phase. Many single-chip semiconductor solutions can accomplish this for low frequency applications using the ...

Frequency response measurements are a mainstay of RF communications design and generally considered a routine task—unless one of the device ports happens to be at I-Q baseband. Here, the convenience ...

A new method for measuring distance based on an optical frequency comb has been unveiled by physicists in the Netherlands. The main benefit of the technique, which involves passing the light from an ...
