- | ===2.3 Plot Plane Axes=== | ||
- | By default, the top pane displays the magnitude response of the circuit network in decibels (from +10dB to -90dB) and the bottom pane displays the phase response of the circuit network 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 displays every frequency in the sweep range (1kHz to 1MHz). The range can be adjusted using the Control Bar. Alternately, | ||

- | <WRAP group> | ||
- | <WRAP column half> | ||
- | ===3.1 Control Bar=== | ||
- | The Control Bar can be found above the plot pane. The control bar contains the Single and Run acquisition buttons, as well as several settings that control the frequency sweep used to probe the circuit under test, accessible via either drop-down menus or text field, . | ||
- | |||
- | * **Scale:** // | ||
- | * **Start & Stop:** Define the frequency range of the sweep. | ||
- | * **Samples: | ||
- | * **/ | ||
- | * **Step:** Controls how many samples are captured during a sweep. Defines the change in frequency between each sample. (Only applicable for Linear scale) | ||
- | |||
- | These settings can also be changed by clicking and dragging the plot or by using the mouse wheel - " | ||

- | ===3.2 Configuration Panel=== | ||
- | To the right of the plot planes is the configuration panel. The top window selects the sweeping signal source and is WaveGen Channel 1 by default. To change to WaveGen Channel 2 or an external source, click the Gear icon ({{: | ||
- | ---- | ||
- | Below the signal source window is the Magnitude plot configuration window. By default, the units are decibels with a ceiling of 10dB and a floor of -90dB. These parameters can be changed by selecting the drop-down menus labeled Units, Top, and Bottom, respectively. | ||
- | ---- | ||
- | Below the Magnitude plot configuration window is the Phase plot configuration window. By default, the Offset and Range are set to 0 degrees and 360 degrees, respectively. To change these values, click the **Offset** and **Range** drop-down menus, respectively. | ||
- | ---- | ||
- | Below the Phase plot configuration window are two Custom measurement windows. By default, these windows are deselected. To add a custom measurement, | ||
- | |||
- | Below the Custom window buttons is a Add Channel button ({{learn: | ||
- | ---- | ||
- | Below the Custom/Add channel buttons are the Channel 1 and channel 2 configuration windows. By default, the Offset and Gain parameters are set to 0 volts and 1x, respectively. To change these values click on or type in the **Offset** or **Gain** fields, respectively. | ||

- | === 3.3 Plot Pane === | ||
- | The plot pane displays data captured on the analog input channels during the stimulus sweep. The horizontal axis of the plot represents the sample frequency. The vertical axis in the top plot represents the gain of the circuit. The vertical axis in the bottom plot represents the phase shift imposed on the test signal by the circuit under test. | ||
