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

Boxcar Function for 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.

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.

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.

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.
