Time Derivative (Dx/Dt)

Calculates and outputs a time-based derivative of the input data.

Location: Time Series -->Time Derivative

Number of Inputs: 1

Type of Inputs: dynamic scalar

Type of Output: dynamic scalar

User Controls: N/A

Time Trend (Trend)

Adjusts the memory buffer used for strip chart acquisitions.

Location: Time Series -->Time Trend

Number of Inputs: 1

Type of Inputs: dynamic scalar

Type of Output: dynamic scalar

User Controls: Buffer Mode, Buffer Size, Clear Buffer

Notes:

A circular buffer stores and displays a fixed number of data points. Once the maximum number of

data points has been reached, each new data point acquired will cause the deletion of the oldest data point
in the buffer. The buffer size is held at a constant value and data acquisition does not stop.

A linear buffer stores a fixed number of points. Data acquisition will stop when the buffer's maximum
number of data points is reached. Use the Buffer Size control to choose how many data points will be
retained in the memory buffer.

The output of this node must be fed into a Unit Labels node or a Graph View node.

Unit Labels (Units)

Alters the x-axis and y-axis labels and units on a graph view or provides the unit on a scalar view.

Location: Constant -->Unit Labels

Number of Inputs: 1

Type of Inputs: scalar or array
