17 +
18 +== GHz ADCs: SP-Devices ADQ412AC ==
19 +
20 +We have ADQ412AC-4G-MTCA digitizer cards for the experiment crates (Exp1, Exp2 and FL2Exp1):
21 +[[ADQ412_datasheet.pdf>>attach:10-0494_C_ADQ412_datasheet.pdf]] ( [[new version>>attach:10-0494-adq412_datasheet.pdf]], [[sampling rates table>>attach:Clocking_AppNote.pdf]])
22 +The cards are connected via Patch panels to the Experimental endstations.
23 +
24 +\\
25 +
26 +* **NOTE: between ADC and Patch panel we have installed an [[EMP protector>>attach:EMP_protector.pdf]] and an additional 1dB attenuator**
27 +* 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"]]

86 +===== ADC and DOOCS / DAQ =====
87 +
88 +The HDF5 names for the ADC traces are depending on the beamline :
89 +\\PG Beamline:
90 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH00/TD{{/code}}
91 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH01/TD{{/code}}
92 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH02/TD{{/code}}
93 +{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH03/TD{{/code}}
94 +
95 +BL Beamlines:
96 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH00/TD{{/code}}
97 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH01/TD{{/code}}
98 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH02/TD{{/code}}
99 +{{code language="none"}}/FL1/Experiment/BL1/ADQ412 GHz ADC/CH03/TD{{/code}}
100 +\\{{code language="none"}}/FL1/Experiment/BL2/ADQ412 GHz ADC/CH00/TD{{/code}}
101 +{{code language="none"}}/FL1/Experiment/BL2/ADQ412 GHz ADC/CH01/TD{{/code}}
102 +\\{{code language="none"}}/FL1/Experiment/BL3/ADQ412 GHz ADC/CH02/TD{{/code}}
103 +{{code language="none"}}/FL1/Experiment/BL3/ADQ412 GHz ADC/CH03/TD{{/code}}
104 +
105 +DOOCS prop : {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00/CH00.TD  or CH00.DAQ.TD{{/code}}
106 +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 ...
107 +DAQ channel: {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00{{/code}}
108 +
109 +in addition there are also additional parameters saved like:
110 +
111 +* sample frequency (in MHz)
112 +* error (state)
113 +* offset
114 +
115 +\\
116 +
117 +== Amplifiers for the GHZ ADCs ==
118 +
119 +* **we can offer [[ Phillips scientific Model 6954>>attach:6954ds.pdf]] amplifiers** to either amplify small signals or to decouple setups which may deliver voltage peaks fro the ADCs.
120 +* The available ADCs 5x, 10x, 20 x 50x and 100x
121 +* The ADCs can be borrowed from Markus Braune
122 +* The Amplifiers fot perfectly to the dynamic range of the GHz ADCs - here a  [[ test of the Phillips scientific amplifier>>attach:Model_6954_Amplifier_Report.pdf]]
123 +
124 +\\
125 +
126 +== 108 MHz ADCs:  Struck SIS8300-L2D ==
127 +
128 +There is one in each of the MTCAs in the hall: MTCA-EXP1 at PG/BL1, the other at BL2 and BL3.
129 +
130 +They are 16 bit, 10 channel, 125 MS/s ADCs.

137 +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).
138 +
139 +Here is a trace of the first signal, a 1 MHz trigger connected from the x2timer board in the same MTCA:

144 +
145 +== Pulse energy server: Using the Struck SIS8300-L2D to detect only integrated values of pulses ==
146 +
147 +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:
148 +
149 +* Peak height: from what signal on (incounts) is the signal to be counted as peak
150 +* 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
151 +* 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.
