Square Root Operator

For each input value, point by point, this math operator takes the square root of the source and places the result in the function waveform. For example, a 10 mV input voltage point results in a 100 mV½; output point. The output units are not V or W. Instead, they are V^½; or W^½;, which are identified on screen as V½; or W½;. The scale of the output waveform does not track the input waveform.

Display Setup

Each operator's setup includes a Setup section that has the selections that are shown in the following generic setup dialog box. Use these settings to control the display of the operator's output waveform, including turning the display on or off. Use the Name field to display an identifying name to the waveform which can be helpful for screen captures or when multiple waveforms are displayed. The settings also include the output waveform's color, scaling, and signal type. The scaling Automatic selection allows the output waveform to track changes to the scaling of the input waveform. This is the setting that you would normally want to use.

The signal Pattern can be used for BER (Bit Error Ratio), SNDR (Signal to Noise and Distortion Ratio), and other measurements. You can specify the math function has the same pattern as the input waveform (Track Input), Auto Detect the pattern, choose a Known Pattern from a list, or specify your own pattern using a Pattern File.
