Here are the new features available in 2020 (old license users can get these features through the Update 2020).
1. Waveform Histogram
Histograms are graphical representations of data which divides it into intervals or bins. These intervals/bins are plotted on a bar chart such that the bar height relates to the number of data points inside each interval/bin as a function of the data value.
The following screenshots shows a series of typical waveforms, withthe associated histograms of the sample values in the blue bar graph.
The histogram gives us an approximation of the probability density function (pdf) of a set of values. The shape of the pdf tells us about the underlying process. In the case of the sine wave, remember that the rate of change of the sine is maximum at the zero crossings and minimum at the positive and negative peaks. When we sample the waveform uniformly, we get more samples at the peaks and much fewer at the zero crossings. This is due to the differences in the rate of change, thus explaining the shape of the histogram. For the case of the triangle wave, the rate of change is constant, so samples are taken evenly. This results in what is called a uniform distribution.
Setting up a Histogram
Press the stats button in the channel of interest until the Histogram chart appear.
2. PWM Generator
This module allow to use the output calibration pin (generally set to 1KHz square wave) to generate a PWM output signal. Max frequency and duty cycle range depends on the device (detail are in each oscilloscope page).
