SodarTools Calibration System (CalSys)

The Sodar Tools Calibration System (CalSys) provides the ability to field test the performance of the Model VT-1 sodar system using a laptop computer. Three software modules are provided: PulseCheck, MakeTone and Transpond.

• PulseCheck captures the Model VT-1 transmit pulse and analyzes it for frequency with ±1-Hz accuracy.
• MakeTone provides a continuous output tone that is selectable in 1-Hz increments and accurate to ±1 Hz. This tone can be used to measure the frequency response of the Model VT-1.
• Transpond generates test signals that simulate a user specified wind speed and wind direction at a user specified height. These test signals can be used to assess the accuracy of the wind data reported by the Model VT-1.

Key Benefits

• Provides convenient means of field testing the Model VT-1
• Certifiable against independent, certified standards
• Increases system confidence level
• Conforms with U.S. guidelines for sodar QA procedures
• Cost-effective compared to alternative means of sodar performance testing
