The appearance of both signals after modifying process.

• Analyzing the Amplitude of the Signal

Peak to peak value setting

• Controlling the Speed of Execution

Time delay setting to 1 sec

The movement of the both signals move more slowly

• Adding a Warning Light

Block diagram of warning light included

Front panel when warning light is included

The warning light will on if the peak exceed the limit value of 2

• Setting a Warning Level Limit

Setting the Level Limit to the >Greater

• Configuring a VI to Save Data to a File

Write to Measurement File setting

The data collected is displayed via Notepad
