19 Frequency Response Analysis
In the Frequency Response dialog box's Chart tab, there are controls for:
• Enabling or disabling the gain or phase plot and table results.
• Adjusting the scroll markers in the plot to see the values measured at particular
locations.
• Viewing additional Chart Controls. The drop-down list lets you select:
• Gain — for controls to adjust the gain plot's vertical scale and offset.
• Phase — for controls to adjust the phase plot's vertical scale and offset.
• Frequency — for controls to adjust the chart's horizontal frequency scale
(starting and ending frequencies). The Adj Mode drop-down selections let
you make normal, fine, or decade (coarse) adjustments to the chart's
starting and ending frequencies.
The Results area table shows: the data point number, the frequency, the waveform
generator output amplitude, the measured gain, and the measured phase. You can
scroll the data.
