Parameter

Description

Input Signal

Displays the input signal.

Displayed signal—Specifies the signal(s) to display in the preview graph(s). This option appears only when you select a group of signals for the input.
Note If the input signals include scalar values that depend on the values of input waveform signals, you cannot specify to display all signals in the preview graph(s).

Autoscale amplitude

Autoscales the preview graph along the y-axis. The default is to autoscale the amplitude.

Averaged Signal

Displays the averaged time signal.

Autoscale amplitude

Autoscale amplitude—Autoscales the preview graph along the y-axis. The default is to autoscale the amplitude.

Configuration

Contains the following options:

Input signal—Specifies the input signal for the step.
Averaging Configuration—Contains the following options:
- Weighting mode—Specifies a linear or exponential weighting mode for the time averaging operation. The default is Exponential.
- Number of avg.—Specifies the number of averages to use for time averaging.
- Averaging mode—Sets the averaging mode. Contains the following options:
  - Running avg.—Specifies to calculate a running average of all input signals for the duration of the operation.
  - Block avg. (auto-restart)—Restarts the averaging process as soon as Avg. count. reaches the value you specify in Number of avg.
Status—Contains the following options:
- Data ready—Indicates when the averaging process is done and the averaged data are ready.
- Avg. counter—Displays the averaging progress.

Advanced Measurement Setup

Contains the following option:

Only return data when ready—Specifies to only return an averaged signal when LabVIEW SignalExpress has processed the number of signals specified in the Number of avg. field.
