Not symmetrical . At this point, it is worth reminding ourselves what a waveform is. Read more on the Pico forum. Is this really the case? The Analog Discovery 2 oscilloscope can also only display a maximum of 50V peak-to-peak, so if your signal was 400V, which the leads we're using can handle but the scope can't display, I can set the switch to 10X and will read 40V on the scope image. endlesik.

Newbie; Posts: 1; Karma: 0 ; AD9833 and oscilloscope - bad waveforms . This example shows how to use Quick-Control Oscilloscope to read waveforms.

But the resource and driver information is different. By Doug Lowe . The Guided Tests are great tools for setting up and performing tests. You can accomplish that using the oscilloscope’s cursors as shown in Figure 2 where relative cursors measure the time difference between the maxima of the two 10 MHz sine waves. The amplitude of the signal is plotted on the vertical axis and time is displayed on the horizontal. Electrical Waveforms Example No2. How to read a waveform on an oscilloscope. These characteristics help define how well you might expect a scope to perform: Bandwidth-- Oscilloscopes are most commonly used to measure waveforms which have a defined frequency. The majority of electronic waveforms encountered when using an oscilloscope are periodic and repetitive, and they conform to a known shape. Read Waveforms Using a Tektronix Scope. You can follow the basic steps using your particular scope. Instrument Control Toolbox™ software supports communication with instruments through Quick-Control Instrument objects. How to read a waveform on an oscilloscope. There are four basic types of waveforms that you’ll run into over and over again as you work with electronic circuits. Many oscilloscope users comment that their digital scopes are “noisy”. Read Waveforms Using Quick-Control Oscilloscope.

Read Waveforms Using Quick-Control Oscilloscope. Simply put, it Often engineers say “they aren’t as clean as their old analogue scopes”. If you are craving more, be sure to check out this How To Use an Oscilloscope video from a couple of our Tektronix experts or visit our website and download the comprehensive 60-page Oscilloscope Guide . This example shows how to use the Quick-Control Oscilloscope to acquire waveforms from an oscilloscope. Reading a waveform with a Tektronix ® scope using Quick-Control Oscilloscope is basically the same workflow as described in Read Waveforms Using Quick-Control Oscilloscope using a Keysight™ scope with VISA. The duty cycle is given as 25% or 1/4 of the total waveform which is equal to a positive pulse width of 10ms. May 10, 2017, 06:34 pm Last Edit: May 10, 2017, 06:39 pm by endlesik. These are examples of possible waveform captures for the specific tests. The Display. A point of difference could indicate a problem. Repetitive waveforms should be symmetrical. On this page we'll discuss a few of the more common systems of an oscilloscope: the display, horizontal, vertical, trigger, and inputs. Key Oscilloscope Specifications.

This example uses a specific instrument, a Keysight™ MSO6104 oscilloscope, but works with any oscilloscope using an IVI-C driver. Some scopes are better than others. Phase difference can be measured on an oscilloscope by finding the time delay between two waveforms and their period. Oscilloscope diagnostics using PicoScope software Pico Technology’s advanced diagnostics software is always on hand to help you, no matter what your experience of capturing component waveforms is. Topic: AD9833 and oscilloscope - bad waveforms (Read 995 times) previous topic - next topic. Why does my Digital Scope Look Noisy? In addition to the Waveform Library, you can also find example waveforms in our growing range of Guided Tests.

You can follow the basic steps using your particular scope. Waveforms are the characteristic patterns that oscilloscope traces usually take.These patterns indicate how the voltage in the signal changes over time — does it rise and fall slow or fast, is the voltage change steady or irregular, and so on.

As pictured above: If the two components of the waveform are not symmetrical, there may be a problem with the signal.

That is, if you were to print the traces and cut them in two like-sized pieces, the two sides should be identical.
