BioAmp signal fed from a DataPipe input results in erroneous data

Tech Note: TN0218
Product: RZ2
Version: All
Date Added: 2006-09-19

Issue

When the DataPipe is used to feed signals from the BioAmp, fixed-point-to-float conversion is required. Omitting the conversion results in erroneous data.

Workaround

The RZ2_Input_MC macro executes the necessary conversion automatically. If the macro is not used in the circuit, the user must place a MCInt2Float or Int2Float with a scale factor of 1e-9 after the PipeIn or MCPipeIn component that feeds the BioAmp signals to the circuit.

Example:

Solution

Use the RZ2_Input_MC macro provided with RPvdsEx.
