The method of analysis of the im pact of interference on the supply lines and ground within the front-end p arts of high-speed transceivers to establish a predominantly circuit macro models with the selected nodes are affected by interference is presented. Unlike the well-known IBIS models\, that contain information on I/O buffer s in the tables with counts of the current-voltage characteristics and tim e-dependency of the output voltage\, the proposed macromodels are deprived of a number of shortcomings and limitations of these models. In particula r\, the possibility of using macromodels are not limited to solving specif ic computational problems related to the analysis of signals integrity. Th is paper shows how to use the proposed macromodels to refine the system pa rameters\, describing the interference of power circuits and ground\, for a wide range of devices and blocks.

The shaper has a function of self-adaption of the shaping time based on t he channel occupancy. The spectrometer consists of the filter with maximiz ed signal-to-noise ratio (slow shaper)\, high-frequency band-pass filter ( fast shaper)\, amplitude and time discriminators\, peak detector and signa l overlap inspector. Based on the channel occupancy the output of either f ast or slow shaper is supplied via the 2-channel multiplexer. At the highe st occupancies the inspector fixes the overlap and the signal from the fas t shaper is switched to the multiplexer output. In case of overlap absence one can use the output of the slow shaper with higher amplitude resolutio n. The estimation of the maximum channel hit rate and amplitude resolution and the structure approbation is considered in the paper.\n\nhttps://indi co.particle.mephi.ru/event/4/contributions/551/ LOCATION:Milan Hotel Vivaldi-Boccerini URL:https://indico.particle.mephi.ru/event/4/contributions/551/ END:VEVENT BEGIN:VEVENT SUMMARY:High voltage source control on FODS DTSTART;VALUE=DATE-TIME:20161014T111500Z DTEND;VALUE=DATE-TIME:20161014T113000Z DTSTAMP;VALUE=DATE-TIME:20260814T153351Z UID:indico-contribution-107-520@cern.ch DESCRIPTION:Speakers: Nikita Kulagin (IHEP)\nThe implementation of the hig h voltage power supply control system (HVPSCS) for experimental setup FODS (FOcusing Doublearmed Spectrometer) at accelerator U-70 of the Federal sta te budgetary institution State Research Center Of Russia Institute for Hig h Energy Physics of the National Research Centre "Kurchatov Institute" (he reinafter referred to as IHEP) or for the test bench of the detector compo nents is considered.\n\nThe required set of hardware is defined and the ap propriate software to operate HVSCS\nis written in C/C++ codes.\n\nThe dat a acquisition (DAQ) system makes automatic control on HVSCS for data takin g\nrun.
