- | In order to measure a signal with the //Spectrum // instrument, there must first be a signal to measure. To this end, step 2.1 of this guide describes setting up a simple loopback circuit that connects the <test & measurement device>' | + | |

- | 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 " | + | |
