Standard modes of MPIA's current H2/H2RG-readout systems

摘要

Even though the last instruments built with the previous generation of MPIA-ROE are offering in the meantime most ofthe standard readout modes, the current generation ROE is based on the experience of the last years, and besides otherproperties like small volume, more channels, less power consumption, etc., it will also allow extended readout modes inthe near future by using the detector engineering and data interfaces of GEIRS.The Hawaii-2-RG detector has a large amount of operational flexibilities to support extended readout modes. Withspecial properties in the pattern generator of the ROE and in GEIRS, new extended readout modes can be implementedidentically for the Hawaii-2 and the Hawaii-2RG in multichannel mode.This paper presents an overview of the standard readout schemes and describes additional selectable options, offeredidle-modes, and some new extended modes available with this generation of MPIA-ROE for the next instruments andinstrument updates using HgCdTe-detectors.During the last 15 years MPIA has built 8 sets of previous readout electronics (ROE) for 8 astronomical infraredinstrumentssup1-8/sup. The generic infrared camera software GEIRS (spoken like 'cheers') is used in these instruments either as apure readout software layer or as an overall control software for IR-instruments, the last case in particular withinstruments for the Calar-Alto observatory in Spain.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
