The demand for ubiquitous wireless communications challenges the physical limitations of current wireless communications systems. When IoT systems operate in a crowded wireless environment on the same
Various combinations of signals in a transmitter and receiver can cause spurious signals. Spurious responses may be a spur from a LO, a harmonic of a power supply, distortion products, or a harmonic o
The most common wireless receiver test is receiver dynamic range which includes minimum input sensitivity, maximum input level, and channel noise. For different wireless standards, the definition of t
Previous posts in this measurement uncertainty series addressed Waveform Discontinuity, Interpolation Shoot, Waveform Sampling Issues, I/Q Impairments, and phase noise. I discussed tactics for minimiz
Accurate microwave measurements are becoming increasingly necessary in harsh and hard-to-reach environments, in a wide range of conditions: day or night, rain or shine, hot or cold, on ship, in an air
Signal generators produce the signals that you need ranging from simple to complex, and from pure to dirty, to test your design. You use signal generators as a local oscillator (LO), a golden transmit
In previous posts, I discussed the source of errors in a baseband generator and strategies for eliminating these errors such as waveform phase discontinuity, interpolation overshoot, and sampling imag
