16 +==== SP-Devices ADQ412AC ====
17 +
18 +We have ADQ412AC-4G-MTCA digitizer cards for the experiment crates (Exp1, Exp2 and FL2Exp1):
19 +[[ADQ412_datasheet.pdf>>url:http://hasfweb.desy.de/pub/Setup/MtcaAdc/10-0494_C_ADQ412_datasheet.pdf||shape="rect"]] ( [[new version>>url:http://hasfweb.desy.de/pub/Setup/MtcaAdc/10-0494-adq412_datasheet.pdf||shape="rect"]], [[sampling rates table>>url:http://hasfweb.desy.de/pub/Setup/MtcaAdc/Clocking_AppNote.pdf||shape="rect"]])
20 +The cards are connected via Patch panels to the Experimental endstations.
21 +
22 +\\
23 +
24 +* **NOTE: between ADC and Patch panel we have installed an [[EMP protector>>url:http://hasfweb.desy.de/pub/Setup/MtcaAdc/EMP_protector.pdf||shape="rect"]] and an additional 1dB attenuator**
25 +* for the influence of the Patch cable and the EMP protector see also [[this logbook entry~[~[image:url:http://hasfweb.desy.de/pub/TWiki/TWikiDocGraphics/external-link.gif~|~|width="13" height="12"~]~]>>url:http://ttfinfo.desy.de/ExpHallelog/show.jsp?dir=/2016/27/08.07&pos=2016-07-08T17:41:07||shape="rect"]]
26 +* we can offer amplifiers to either amplify small signals or to decouple setups which may deliver voltage peaks fro the ADCs. The available ADCs are:
27 +** 20 dB, 1 GHz, 50 Ohm, ( [[Minicircuits ZFL-1000LN+>>url:http://hasfweb.desy.de/pub/Setup/MtcaAdc/ZFL-1000LN.pdf||shape="rect"]])
28 +** 10 dB, 1.8 GHz, 50 Ohm, ( [[Becker und Hickl, ACA-1-10-I>>url:http://hasfweb.desy.de/pub/Setup/MtcaAdc/ACA-amilifier.pdf||shape="rect"]])

93 +===== ADC and DOOCS / DAQ =====
94 +
95 +The HDF5 names for the ADC traces are depending on the beamline :
96 +\\PG Beamline:
97 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH00/TD{{/code}}
98 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH01/TD{{/code}}
99 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH02/TD{{/code}}
100 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH03/TD{{/code}}
101 +
102 +BL Beamlines:
103 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH00/TD{{/code}}
104 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH01/TD{{/code}}
105 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH02/TD{{/code}}
106 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH03/TD{{/code}}

108 +{{code language="none"}}/FL1/Experiment/BL2/ADQ412 GHz ADC/CH01/TD{{/code}}
109 +\\{{code language="none"}}/FL1/Experiment/BL3/ADQ412 GHz ADC/CH02/TD{{/code}}
110 +{{code language="none"}}/FL1/Experiment/BL3/ADQ412 GHz ADC/CH03/TD{{/code}}
111 +
112 +DOOCS prop : {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00/CH00.TD  or CH00.DAQ.TD{{/code}}
113 +here the {{code language="none"}}CH00.TD{{/code}} is the full ADC trace as it is sampled ( typically several 100.000 samples per pulse train) while the {{code language="none"}}CH00.DAQ.TD{{/code}} trace only has the number of samples which are sent to the DAQ OR if //grouping// is actvated the {{code language="none"}}CH00.DAQ.TD{{/code}} contins only the grouped spectra. To read the ADC trace with an online analysis program the {{code language="none"}}CH00.DAQ.TD{{/code}} is preferable to use ...
114 +DAQ channel: {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00{{/code}}
115 +
116 +in addition there are also additional parameters saved like:
117 +
118 +* sample frequency (in MHz)
119 +* error (state)
120 +* offset

124 +==== Struck SIS8300-L2D ====
125 +
126 +There is one in each of the MTCAs in the hall: MTCA-EXP1 at PG/BL1, the other at BL2 and BL3.
127 +
128 +They are 16 bit, 10 channel, 125 MS/s ADCs.

135 +50 Ohm input impedance, -1 V,...,+1 V default input range, analog signals can be routed to AC and DC input stage. The coupling is DC via op-amp (switching to AC transformer involves resoldering of SMD solder bridges).
136 +
137 +Here is a trace of the first signal, a 1 MHz trigger connected from the x2timer board in the same MTCA:

142 +
143 +==== Using the Struck SIS8300-L2D to detect only integrated values of pulses ====
144 +
145 +FS-LA (Falko Peters) programmed a pulse detection server that automatically detects peaks in the signel and integrates the samples around the peak. <\br> things to set:
146 +
147 +* Peak height: from what signal on (incounts) is the signal to be counted as peak
148 +* pre and post peak integration time: how much ns to be integrated before and after the peak sample that are taken into account for the peak
149 +* pre and post peak noise time: before and after the samples that are taken for the actual signal these samples are used as background ( they also can be used to define the "deadtime" of the detector before it searches for new peaks.
