- | By default, the plot vertical axis units are decibel volts (dBV) from -200dBV to 0dBV and the horizontal axis is frequency from 0MHz to 1MHz. To change these values, use the Control Bar located above the plot plane or the Configuration Panel located to the right of the plot plane which are discussed in subsequent sections. With the Spectrum tool running, the plot should show a large " | + | |

- | ==3.2 Additional Control Bar Parameters== | + | |
- | For further controls, click the wide, downward arrow button on the right side of the Control Bar. This will bring down an additional row of parameters: scale, center frequency, frequency span, and number of samples. To change these parameters (except Samples), click on the drop down arrow or type in the text field. Click the gear icon to change the acquisition algorithm and enable control of the Resolution and Samples parameters. | + | |
