Developed on the Keysight PathWave software platform, […]
Checking power line quality with test instruments
The average homeowner probably doesn’t think about the quality of the electrical power coming out of household wall sockets. But that’s not the case for large industrial facilities where capacitive, inductive, and non-linear electrical loads can be large enough to distort the ac waveform. In those cases, electrical power quality becomes an important measurement. Electric […]
AWGs provide 24 to 48 channels of 60-MHz signals
Designed for engineers and scientists who need to simultaneously generate multiple electronic test signals, Spectrum Instrumentation’s latest line of Arbitrary Waveform Generators offers 24 to 48 synchronous channels in a single rack-unit with an economic cost-per-channel. The eight different variants achieve full remote control through a simple Ethernet connection to any PC or local area […]

Available in 2.1-GHz and 3.6-GHz models with a starting price of only $3,699, the DSG800A provides the most capable and affordable IQ generation product on the market. […]
Real-time spectrum analyzers carry economical price tag
A low-cost Real-Time Spectrum Analyzer called the RSA3000E brings the power of UltraReal real-time analysis to a new class of customer who previously had no access to this advanced capability. The RSA3000E combines the power of a high-performance Swept Spectrum Analyzer with the analysis capability of a Real-Time Analyzer at an unprecedented entry-level price point. […]
Understanding instrumentation for measuring total harmonic distortion
When discussing total harmonic distortion (THD), the fundamental of the wave in question is known as the first harmonic. Quantifying THD, therefore, begins with the second harmonic. Theoretically, the number of harmonics is limited only by some maximum frequency based on minimum quantum wavelength. In reality, however, we are interested in a relatively small number […]
Software speeds double-pulse testing with AFGs
A new software plugin for the AFG31000 Arbitrary/Function Generator makes it possible to perform crucial double pulse testing in less than a minute, saving a significant amount of time when compared to alternative methods. With the new Double Pulse Test software, engineers can quickly define pulse parameters from a single window on the AFG31000’s large […]
Programmable ac power sources now include 18-kVA model
The Asterion 12K3 supplies ac and dc output power up to 12,000 VA or 12,000 W, and the Asterion 18K3 supplies up to 18,000 VA or 18,000 W. Both units come in a 14U chassis and can supply single- or three-phase output power. Like the lower-power 1U, 2U and 4U models, Asterion Models 12K3 and […]
Morse code, the first serial communication protocol
Today we tend to take for granted the fact that even PC-based oscilloscopes can automatically record and decode packets or frames sent via serial protocols such as 1-Wire, RS-232, and Ethernet. But back in olden times, the decoding of serial protocols was a job for humans. We are speaking, of course, of what was probably […]
