- | ===== Introduction ===== | + | |
- | This guide explains the use of the //Network// instrument in WaveForms. This instrument is used to measure the frequency response of a circuit-under-test. | + | |
- | ---- | + | |
- | ===== Prerequisites ===== | + | |
- | * A Digilent Test & Measurement Device with Analog Input and Output Channels | + | |
- | * A Computer with WaveForms Software Installed | + | |

- | Plug in your Test & Measurement Device, then start WaveForms and make sure your device is connected. | + | |
- | + | ||
- | If no device is connected to the host computer when WaveForms launches, the **Device Manager** will be launched. Make sure that the device is plugged in and turned on, at which point it will appear in the Device Manager' | + | |

- | ==2.3 Plot Plane Axes== | + | |
- | By default, the top pane displays the magnitude response of the network port in decibels (from +10dB to -90dB) and the bottom pane displays the phase response of the network port in degrees (from +180° to -180°). These respective values are on the left side vertical axis and are adjusted using the configuration panel. | + | |
- | + | ||
- | The bottom axis is shared by both plots and by default is frequency from 1kHz to 1MHz. This axis can be adjusted using the control bar. Alternately, | + | |

- | To place one or more normal or delta cursors, click the Add Cursor button in the bottom left plane. The first click will generate a normal cursor and repeated clicks will generate additional delta cursors referenced to the first cursor. To change the delta cursors to a normal cursor, click the arrow icon on that cursor' | + | |
