Overview

The DXP is a Digital Signal Processor based multichannel analyzer from X-ray Instrumentation Associates. It is a single-width CAMAC module with up to 4 input channels. Each channel contains the equivalent electronics of the shaping amplifier, ADC and MCA of a conventional pulse-height analysis system. The Saturn model has the same functionality, but is packaged as a standalone box, and is interfaced with an Enhanced Parallel Port (EPP) interface.  Support for the DXP modules under EPICS is provided in the following manner:

  1. Device support for the MCA record. This permits each channel of the DXP to be connected to an MCA record identically with other supported MCA hardware, including the Canberra AIM.

  2. A new DXP record. This record is used to set all of the many software selectable parameters for the DXP, including shaping times, pileup rejection criteria, etc.
