Integrating the ORTECH 438 BaseLine Restorer into your analysis system involves several key considerations to ensure optimal performance. Begin by connecting the 438 as the final stage before pulse height analysis. If your system includes a nonlinear element without a restoration circuit, address this. De-couple the nonlinear element up to its bias point and perform restoration before it to preserve pulse height resolution. Ensure proper de-coupling of the pulse height analysis system after the restorer. Consider the ADC: Some ADCs may lack internal de-coupling at their input. For high count rates, perform external de-restoration and couple directly into the ADC's normal mode. If count rates are extremely high, utilize external de-coupling in the ADCs and use the 438 for external de-restoration. Consult the manufacturer's recommendations for specific methods of connecting the 438 to your multichannel analyzer, as these may vary. Pay close attention to signal integrity. When connecting linear signals, consider the source impedances of the outputs and terminate cables appropriately to prevent signal reflections or oscillations. Use the 93-ohm output for series termination of the cable. Terminate the cable correctly at the receiving end to avoid signal loss. Proper implementation of these steps will allow you to successfully incorporate the ORTECH 438 BaseLine Restorer, ensuring its optimal function within your analysis system.
