28 Bode Plot

28.1 Overview

The SDS5000X supports an automatic bode plot function. This function

provides a frequency response curve of the device-under-test as well as the

interface for output sweep parameter control and data display settings. At this

time, either the SIGLENT SAG1021I arbitrary waveform generator or one of a

SIGLENT SDG series arbitrary function generators are supported. During the

sweep, the oscilloscope configures the generator output frequency and

amplitude and then compares the input signal to the output of the DUT. Gain

(G) and phase (P) are measured at each frequency and plotted on the

frequency response bode plot. When the loop response analysis is complete,

you can move the markers on the chart to see the gain and phase values

measured at each frequency point. You can also adjust the scale and offset

settings for the amplitude and phase plots.
