Shenzhen, Jiangxi -- (SBWIRE) -- 11/21/2011 -- Arbitrary waveform generators, or AWGs, are sophisticated signal generators which allow the user to generate arbitrary waveforms, within published limits of frequency range, accuracy, and output level. Unlike function generators, which are limited to a simple set of waveforms; an AWG allows the user to specify a source waveform in a variety of different ways. AWGs are generally more expensive than function generators, and are often more highly limited in available bandwidth; as a result, they are generally limited to higher-end design and test applications.

An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and analyzed as they progress through the device, confirming the proper operation of the device or pinpointing a fault in the device.

Unlike function generators, AWGs can generate any arbitrarily defined wave shape as their output. The waveform is usually defined as a series of "waypoints" (specific voltage targets occurring at specific times along the waveform) and the AWG can either jump to those levels or use any of several methods to interpolate between those levels.

An arbitrary waveform generator (AWG) is an advanced signal generator that can generate a waveform of almost any shape. The generated waveform can then be inserted into the device you wish to test and then analyzed as it progresses through the device to confirm correct operation, or to highlight a fault.

Arbitrary waveform generators are often expensive and so are usually only found in high–end test equipment, however, several PC Oscilloscopes include a built–in AWG. The arbitrary waveform generator is programmed with a data file, supplied by the user, which defines the output voltage at a number of equally spaced points in time. The circuit uses this data to reconstruct the waveform with a specified amplitude and frequency.

London , England -- (SBWIRE) -- 11/01/2011 -- Oscilloscopes play a very important role in the design & development of various electronic systems. The current market is flooded with a host of oscilloscopes, however there are very few that are affordable & user friendly. User friendly file system always built-in digital oscilloscopes, so you can store what you want in the flash drive or download to your computer.

PC Oscilloscopes use the PCs you already own so give large color displays (so the whole class can see) and the ability to save and print waveforms. Data can easily be exported to other Windows applications for further analysis or for writing reports.

All the required software is included with the products, there are no licensing requirements — you can use the software on as many PCs as you like, and free software updates are available from our website. Most PC oscilloscopes are limited to the capture of a few million points of information, which is useful for human eye analysis, they offer little to no custom programming options, produce low dynamic range data and are not always easy to control or transfer data from within an embedded environment. PC based oscilloscopes offer a cost effective and portable solution for traditional bench-top oscilloscopes.

A new type of "oscilloscope" is emerging that consists of a specialized signal acquisition board which can be an external USB or Parallel port device or an internal add-on PCI or ISA card. The chief benefit of a quality oscilloscope is the quality of the trigger circuit. If the trigger is unstable, the display will always be fuzzy. The quality improves roughly as the frequency response and voltage stability of the trigger increase.

The Oscilloscope and all you need to perform a variety of experiments, including determining the speed of sound and demonstrating Faraday's Law. The dual-channel PC Oscilloscope is capable of real-time sampling rates of up to 200 mega samples per second, has a 25 MHz analogue bandwidth and a 16,000 sample buffer memory. It comes with software, which runs under Windows. A PC Oscilloscope is very light and compact, so it is convenient to carry your results in a flash drive.

The systems are not a replacement of, but rather an answer to, conventional test equipment deficiencies, while still providing the highly integrated, user-friendly commercial off-the-shelf (COTS) product characteristics that allowed the oscilloscope, spectrum analyzer and signal generator to become so widely used within the Test & Measurement industry.

Shenzhen, Guangdong -- (SBWIRE) -- 09/18/2011 -- The digital oscilloscope is an indispensable tool for anyone designing, manufacturing or repairing electronic equipment. In today's fast-paced world, engineers need the best tools available to solve their measurement challenges quickly and accurately.

As the eyes of the engineer, digital oscilloscopes (DSO) are the key to meeting today's demanding measurement challenges. The usefulness of a digital oscilloscope is not limited to the world of electronics. With the proper sensor, a digital oscilloscope can measure all kinds of phenomena. A sensor is a device that creates an electrical signal in response to physical stimuli, such as sound, mechanical stress, pressure, light, or heat. A microphone is a sensor that converts sound into an electrical signal.

DSO oscilloscopes are used by everyone from physicists to repair technicians. An automotive engineer uses a digital oscilloscope to correlate analog data from sensors with serial data from the engine control unit. A medical researcher uses a digital oscilloscope to measure brain waves. The possibilities are endless.

A digital phosphor Oscilloscope (DPO) is a digital oscilloscope but instead of a CRT, it uses a digital flat panel display, usually a liquid crystal panel. These are becoming the de facto digital oscilloscope system. With the relentless march of technological progress: DPOs can offer significant enhancements over traditional oscilloscopes, such as different color traces for different inputs or signal types or even parts of the displayed signal. Also a DPO can emulate long persistence phosphors in traditional CRT systems. Many designs can also provide near real time information on the displayed waveform such as amplitude (including average; peak; peak to peak; and RMS), repetition rate and even more complex functions such as flourier transforms.

Digital oscilloscopes have many advantages over its analog counterpart, like the ability to capture single events, and to display what happens before the trigger. You also can build a digital oscilloscope simply by hooking an ADC and an FPGA together.

Jiangxi, China -- (SBWIRE) -- 09/14/2011 -- With the significantly change of the digital technology, digital devices all have changed much. There is a big difference between digital equipment and analog equipment. Digital storage oscilloscope adds a LED screen and a data storage memory. These features made these digital oscilloscopes more accurate.

Instructions

Continuous Sweep Mode

1. Make the probe hook up to your storage oscilloscope and the device which you are going to test. You also should connect the reference voltage.

2. Choose "Volts/Division", made small signal appear, however this will depend on the capabilities of your oscilloscope. You should guarantee that any magnification and zoom features don't work.

3. Set the capture mode to "Auto". Trigger can capture a transient event after starting using.

4. "Run" button can help you enter capture mode. The measured signal should be centered on the screen. If not, you can do it by setting the vertical and horizontal position.

5. Setting the horizontal resolution of the waveform by the frequency of the signal. "stop" or "run" can help you to pause the display.

Triggered Sweep Mode

1. You can set the capture mode "Normal" or "Trigger" to determine the sweep function.

2. Choose a trigger you want. Rising edge and falling edge are provided by digital storage oscilloscope. You can choose a trigger according the signal that you are going to capture.

3. Different trigger type decides different setting. Such as pulse width, the rise time, these can be set as your trigger.

4. You can watch the waveform process after you paused the display, as digital storage oscilloscope can storage the data information. This is good for you to view and study the waveform.

5. An advantage of digital storage oscilloscope is having a large memory. You can storage a long fragment for a further analysis. Just setting a few values of the "Time/Division". Increase or decrease is depending on whether need to zoom in the waveform.
