Traditionally, only the spectrum analyzer was capable of displaying electrical and electromagnetic signals in the frequency domain and the oscilloscope took control of the time domain. More recently, each instrument has become competent in the other’s territory. But this overlapping tendency is far from absolute. Oscilloscopes, working in the Math>FFT mode, have always had a […]
Economical scopes sample at 2 GSa/sec with standard record length of 28 Mpts/channel
New economical, high-performance Siglent SDS2000X-E Series Super Phosphor Oscilloscopes are available in 200 MHz and 350 MHz bandwidths. They feature a maximum sampling rate of 2 GSa/sec and a standard record length of 28 Mpts/ch (interleaved mode). With an impressive waveform capture rate of up to 400,000 frames/sec (sequence mode) Siglent’s newest oscilloscope series supports […]
RF 2.1 GHz/3.2 GHz signal generators controlled via touch, PC, or web
The Siglent SSG3000X RF Signal Generators have a frequency range of 9 kHz to 2.1 GHz or 3.2 GHz. They provide all of the common signal-generation needs such as sweep control and analog modulations (AM, FM, PM) as well as pulse modulation and pulse train generation (option). Additionally, the IQE models can be used with […]
Spectrum and vector network analyzer works to 1.5 GHz, carries budget price
The new Model SVA1015X Spectrum and Vector Network Analyzer has frequency ranges from 9 kHz to 1.5 GHz, (VNA frequency range is 10 MHz – 1.5 GHz) and starts at $1,395. This next generation test instrument provides exceptional measurement precision with a wide range of RF measurement functions for RF device testing, broadcast evaluation, site […]
Measuring phase noise and jitter
Generally, whether one speaks of phase noise or jitter depends upon whether they happen to be a radio frequency or digital systems engineer. Both phenomena are random fluctuations of a time-domain waveform in an oscillator or in a clock. Phase noise is best represented in the frequency domain. It is usually defined as the spectral […]
Exploring the Siglent SHS 1102 hand-held oscilloscope through use of reference and recorder functions
The word oscilloscope is mostly used to refer to a bench-type instrument, but scopes also exist as hand-held, battery-powered versions. The bench-type oscilloscope, model-for-model, usually has more features, higher specifications such as bandwidth and sampling rate, more controls, deeper menus and so on. The hand-held, battery-powered oscilloscope, in contrast, is smaller and more portable, well-sealed […]

Locating and Evaluating Harmonics Using the Siglent SSA 3032X Spectrum Analyzer
What is a harmonic? A harmonic of a repeating wave is a wave with a frequency that is a positive integer multiple of the original, known as the fundamental frequency. The original wave is also called the first harmonic, and the following harmonics are known as higher harmonics. With regard to a 60-Hz electrical system, […]

Exploring frequencies with a Siglent SSA 3032X spectrum analyzer
A lab that aspires to do advanced electronic research or product development must have one or more oscilloscopes and spectrum analyzers. Despite their obvious similarities, the two are totally different instruments. The oscilloscope functions in both time and frequency domains, the latter by means of its math/FFT (Fast Fourier transform) capability. The spectrum analyzer, in […]

Product review -– Siglent SDG2000X series arbitrary waveform generator
Most high-spec contemporary oscilloscopes include as an option a built-in arbitrary function generator. Engineers use this feature on a daily basis. It goes well with the many other capabilities in today’s amazing digital storage oscilloscopes, and one would not want to be without it. However, a well-equipped bench will usually have a stand-alone arbitrary waveform […]
