Standard waveforms and eye parameters
The PicoScope 9400 Series oscilloscopes quickly measure well over 40 standard waveforms and over 70 eye parameters, either for the whole waveform or gated between markers. The markers can also make on-screen ruler measurements, so you don’t need to count graticules or estimate the waveform’s position. Up to ten simultaneous measurements are possible. The measurements conform to IEEE standard definitions, but you can edit them for non-standard thresholds and reference levels using the advanced menu, or by dragging the on-screen thresholds and levels. You can apply limit tests to up to four measured parameters.
Waveform measurements with statistics
Waveform parameters can be measured in both X and Y axes including X period, frequency, negative or positive cross and jitter. In the Y axis measurements such as max, min, DC RMS and cycle mean are available. Measurements can be within a single trace or trace-to-trace such as phase, delay and gain. Selection of a measurement parameter displays its values, thresholds and bounds on the main display.
Eye diagram measurements
The PicoScope 9400 Series scopes quickly measure more than 70 fundamental parameters used to characterize non-return-to-zero (NRZ) signals and return-to-zero (RZ) signals.
PicoSample 4 has a built-in library of over 130 masks for testing data eyes. It can count or capture mask hits or route them to an alarm or acquisition control. You can stress- test against a mask using a specified margin, and locally compile or edit masks. There’s a choice of gray-scale and color-graded display modes, and a histogramming feature, all of which aid in analyzing noise and jitter in eye diagrams. There is also a statistical display showing a failure count for both the original mask and the margin. The extensive menu of built-in test waveforms is invaluable for checking your mask test setup before using it on live signals.
Powerful mathematical analysis
The PicoScope 9400 Series scopes support up to four simultaneous mathematical combinations or functional transformations of acquired waveforms. You can select any of the mathematical functions to operate on either one or two sources. All functions can operate on live waveforms, waveform memories or even other functions. There is also a comprehensive equation editor for creating custom functions of any combination of source waveforms. • Choose from 60 math functions, or create your own. • Add, subtract, multiply, divide, invert, absolute, exponent, logarithm, differentiate, integrate, inverse, FFT, interpolation, smoothing, trending and boolean bit operation.
All PicoScope 9400 Series oscilloscopes can calculate real, imaginary and complex Fast Fourier and Inverse Fast Fourier Transforms of input signals using a range of windowing functions. The results can be further processed using the math functions. FFTs are useful for finding crosstalk and distortion problems, adjusting filter circuits, testing system impulse responses and identifying and locating noise and interference sources.
Behind the powerful measurement and display capabilities of the 9400 Series lies a fast, efficient data histogram capability. A powerful visualization and analysis tool in its own right, the histogram is a probability graph that shows the distribution of acquired data from a source within a user-definable window. Histograms can be constructed on waveforms on either the vertical or horizontal axes. The most common use for a vertical histogram is measuring and characterizing noise and pulse parameters. A horizontal histogram is typically used to measure and characterize jitter.
