Siglent launched its first 1GHz Oscilloscopes
29 January 2019 - Siglent launched the new economical, high performance SDS5000X series of digital storage oscilloscopes, which are available in 2 or 4 channel versions with bandwidths of 350MHz, 500MHz, and 1GHz. With a maximum sample rate of 5GSa/s, these scopes offer a maximum record length of 250Mpts to allow for deep memory investigation of glitches and infrequent events, and they also have the option of 16 digital channels for true mixed signal analysis.
Analyzing Frequency Response with Oscilloscopes
21 January 2019 - Rohde & Schwarz has extended the application range of its R&S RTB2000, R&S RTM3000, and R&S RTA4000 oscilloscopes with a new option for frequency response analysis. Equipped with the R&S RTx-K36, the oscilloscopes can display Bode plots for both phase and gain against frequency simultaneously. With the new software option, users can analyze the response to frequency changes from 10 Hz up to 25 MHz without any additional piece of equipment and at a fraction of the price of dedicated solutions.

A Comparison between Oscilloscopes and Spectrum Analyzers
Whether it is for a land survey searching for minerals on Earth, or for a space exploration in search of alien life forms, the analysis of any signal boils down to looking at its time and frequency information. While an oscilloscope displays a signal with respect to time, a spectrum analyzer shows it with respect to frequency. Both of these tools are very important in any signal analysis application. This article explains the difference between oscilloscope and spectrum analyzer using examples.

A simple method to verify the bandwidth of your probe
In oscilloscopes or oscilloscope probes, bandwidth is a measure of the width of a range of frequencies measured in Hertz. Specifically, bandwidth is specified as the frequency at which a sinusoidal input signal is attenuated to 70.7 percent of its original amplitude, also known as the -3 dB point. Most oscilloscope companies design the scope/probe response to be as flat as possible throughout its specified frequency range, and most customers simply rely on the specified bandwidth of the oscilloscope or oscilloscope probes, wondering if they are indeed getting the bandwidth performance at the probe tip. Now you can use these step-by-step instructions to simply measure and verify the bandwidth of your probe with an oscilloscope you may already have.
