I/O Waveform Controls and Indicators

Waveform Control

Use the waveform control to manipulate individual data elements of a waveform. The waveform control carries the data, start time, and delta t of a waveform.

Digital Waveform Control

Use the digital waveform control to manipulate the individual elements of a digital waveform. Use the digital waveform control to specify start time, delta t, the data, and the attributes of a digital waveform. The digital waveform control stores data using a digital table.

The digital waveform control in Figure 4. Elements of a Digital Waveform Control displays digital data with six samples that each contain eight signals, a start time of 6:00 PM on 1/31/2007, and delta t of 1.

Digital Data Control

The digital data control displays digital data arranged in rows and columns as a digital table. Use the digital data control to build digital waveforms or to display digital data extracted from a digital waveform.

To view the samples and signals of a digital waveform, wire the digital waveform data control to a digital data indicator.

The digital data control in Figure 5. Elements of a Digital Data Control displays six samples that each contain eight signals.

You can insert and delete rows and columns in the digital data control. Use the shortcut menu to cut, copy, and paste digital data within the control.

You can display the data in the digital data control in binary, hexadecimal, octal, and decimal formats. The digital states L, H, Z, X, T, and V, which are states some measurement devices use, appear as question marks in the control if you choose to display the values in hexadecimal, octal, or decimal format. Right-click the control, select Data Format from the shortcut menu, and select a data format for the control.
