Plotter Tab

The Plotter is one of the powerful time-domain measurement tools as introduced in Unique Set of Analysis Tools and is available on all GHFLI instruments.

Features

  • Vertical axis grouping for flexible axis scaling

  • Polar and Cartesian data format

  • Histogram and Math functionality for data analysis

  • 4 cursors for data analysis

  • Support for Input Scaling and Input Units

Description

The Plotter serves as graphical display for time domain data in a roll mode, i.e. continuously without triggering. Whenever the tab is closed or an additional one of the same type is needed, clicking the following icon will open a new instance of the tab.

The maximum duration data is kept in the memory can be defined through the window length parameter in the Settings sub-tab. The window length also determines the file size for the Record Data functionality.

Setting the window length to large values when operating at high sampling rates can lead to memory problems at the computer hosting the data server.

Select a Preset

Select a pre-defined group signals. A signal group is defined by a common unit and signal type.

They should have the same scaling behavior as they share a y-axis. Split a group if the signals have different scaling properties.

Enabled Demods R

Selects the amplitude of all enabled demodulators.

Enabled Demods Cartesian

Selects X and Y of all enabled demodulators.

Enabled Demods Polar

Selects amplitude and phase of all enabled demodulators.

Unpopulated

Shows no signals.

Manual

Selects the signals as defined in the tree sub-tab.

For the Vertical Axis Groups, please see the table "Vertical Axis Groups description" in the section called "Vertical Axis Groups".

For the Math sub-tab please see the table "Plot math description" in the section called "Cursors and Math".
