Spectrum's New Boxcar Function Smooths Out Noise to Give Clear Signals

Spectrum GmbH has announced a new function for its extensive range of modularly designed digitizers. The Boxcar averaging function smooths out high frequency noise to give a clear signal. It is most useful in situations where signals have been oversampled and it can be used to increase vertical resolution, lower noise and improve dynamic characteristics such as signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR). It uses a mathematical signal processing function to effectively recalculate the vertical value of each acquired data point by averaging it with adjacent sample points.

Creating, Capturing and Transferring AWG Waveforms

Creating, capturing and transferring waveforms for arbitrary waveform generators using SBench 6.


Spectrum Catalogue - Precision and Performance in PC Instrumentation

The latest Spectrum catalogue that summarizes current instrumentation range.


Creating AWG Waveforms in SBench 6 using Equations

Arbitrary waveform generators (AWG's) are among the most powerful signal sources available for testing. They offer an extensive range of waveshapes which can be created and selected to rapidly provide a broad range of test events. This application note provides an overview of the rules for waveform creation along with a series of detailed examples. Let’s start with an overview of the waveform creation elements available in SBench 6.


SBench 6 - Software Tool for Digitizer Data

Modular digitizers are typically small compact devices that allow the capture and conversion of analog electronic signals into digital data. The data can then be stored in on-board memory or transferred to a PC. As digitizers are ‘blind’ instruments they do not normally have an integral display to view, measure or analyze the data they collect. Instead, these functions are usually performed by a PC. Thanks to today’s technology PC’s offer massive amounts of processing power, large displays and huge storage capabilities. Notebook PC’s can even be used to provide easy portability in remote or mobile applications.  


LXI based Multi-channel Digitizer Instrument

Have you ever been challenged to take multiple measurements in a short period of time? In this article we will discuss the key features of the digitizerNETBOX, an LXI digitizer instrument, and demonstrate how it can make real world measurements on an air compressor. We’ll show how to install and connect the instrument and then set up the measurement with the included software - all within a few minutes.


Software Support for Modular Digitizers

Although modular digitizers can be considered computer hardware they require suitable firmware and software in order to be integrated into the host computer system. Digitizers use embedded software and require device drivers, maintenance software and operational applications to control, view and transfer the digitizer’s data. Software can be supplied or it can be custom developed, this application note provides an overview of the software required to support modular digitizers.


Triggering and Synchronization in Modular Digitizers

Digitizers are used to convert electrical signals into a series of measurements that are then output as a numerical array of amplitude values versus time. To make this information useful the time information is typically related to a specific reference point which is most commonly the trigger position. The trigger point can be something that occurs within the measured signal or it can be from other external sources. The function of triggering is to link the time measurements to a specific known point in time.


Proper Use of Digitizer Front-End Signal Conditioning

Modular digitizers and similar measuring instruments need to match a wide variety of signal characteristics to the fixed input range of the internal analog to digital converter (ADC). Digitizer front ends must also minimize loading of the device being tested and provide appropriate coupling. Additionally, filtering may be needed to reduce the impact of broadband noise. All of these features are provided by the instruments ‘front end’ which includes all the circuitry between the input and the ADC. 


Using Modular Digitizer Acquisition Modes

Modular digitizers offer many acquisition features matched to the primary application of acquiring multiple channels of input data and transferring that data at high rates to analysis computers. They also offer multiple acquisition modes that are intended to use on-board memory efficiently and decrease the dead time between acquisitions. This is especially true with signals that occur at low duty cycles in such applications as echo ranging (including radar, sonar, lidar, and ultrasound), and transient data collection applications (such as time of flight spectrometry and other stimulus-response based analysis).


Advantages of High Resolution in High Bandwidth Digitizers

Two of the key specifications of digitizers are bandwidth and amplitude resolution. These specifications are not independent - with increasing resolution available with decreasing bandwidth. Users must make a tradeoff in selecting a digitizer to meet their measurement needs. This article discusses the advantages and limitations of high resolution in high bandwidth digitizers. Where high resolution is greater than 12 bits and high bandwidth is greater than 20 MHz.


An Introduction to Modular Waveform Digitizers

This article provides general information about digitizers. The article explains in detail different features and the difference between digitizers and digital oscilloscopes. In addition this article provides a glossary of common digitizer specifications and terms. 


Signal Processing for Digitizers

Modular digitizers allow accurate, high resolution data acquisition that can be quickly transferred to a host computer. Signal processing functions, applied in the digitizer or in the host computer, permit the enhancement of the acquired data or the extraction of extremely useful information from a simple measurement. Modern digitizer support software, like Spectrum’s SBench 6 and many third party programs incorporate many signal processing features. These include waveform arithmetic, ensemble and boxcar averaging, Fast Fourier Transform (FFT), advanced filtering functions and histograms. This application note will investigate all these functions and provide typical examples of common applications for these tools.


Using Spectrum Digitizers in Ultrasonic Applications

The use of Ultrasonic products is increasing as new techniques and improvements in instrument performance constantly expand the range of applications. Spectrum digitizers are ideal tools for making ultrasonic measurements and can play a key role required in the development, testing and operation of these products.


Using Digitizers as Oscilloscopes

This application note discusses using digitizers as oscilloscopes.


Using Probes and Sensors with Modular Digitizers

Probes convert signal levels, change impedance levels, or offer convenient connection methods. Sensors or transducers convert physical phenomena to electrical signals. Examples include current probes, accelerometers, and photomultipliers. Both types of input devices are supported by Spectrum digitizers. This application note deals with using both probes and sensors with Spectrum modular digitizers.


RF Measurements Application Note

Modern modular digitizers, like the Spectrum M4i series PCIe digitizers, offer greater bandwidth and higher resolution at any given bandwidth than ever before. Although they are in the class of general purpose measuring instruments they are capable of many RF and lower microwave frequency measurements. This article focuses on some examples of common RF measurements that can be performed with these modular digitizers.
