Changing the view in one graph also changes the view in the remaining three graphs. | | --- | --- | | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-P3NNQ8CR.png) | The slider enables you to turn on and off the collection of power logging data. | | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-CVHIDBFO.png) | Time range of the graph. | | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-PD8N8QEQ.png) | By clickng on the channels, they appear or disppear from the graph. | | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-RQT1S4SB.png) | Refresh of the graph. | | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-3OZ22LS1.png) | Saves the graph as image. | ## Graph types | **RMS Power Limiter:** Logs and visualizes the continuous average power output for individual channels and the total system. | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-NIOL79AM.png) | | --- | --- | | **Peak Power Limiter:** Captures transient power spikes and maximum output levels in real-time. Helps identify dynamic limits and potential clipping points during high-energy signal bursts. | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-HZS4VC9L.png) | | **Limiter Gain Reduction:** Tracks protective attenuation activity across all channels and PSU rails. Shows when and by how many decibels the system reduces gain to protect the hardware. | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-Z9D9M4OU.png) | | **Thermal Monitoring:** Provides a historical view of operating temperatures for all channels, the heatsink, and the transformer. | ![](https://cdn.document360.io/a3e67867-6316-451b-94ad-ec727ac9102a/Images/Documentation/image-KJBHQNW0.png) |
