18 -We have ADQ412AC-4G-MTCA digitizer cards for the experiment crates (Exp1, Exp2 and FL2Exp1):
19 -[[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]])
20 -The cards are connected via Patch panels to the Experimental endstations.

23 -
24 -* **NOTE: between ADC and Patch panel we have installed an [[EMP protector>>attach:EMP_protector.pdf]] 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 [[ 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. The available ADCs
27 -* 5x, 10x, 20 x 50x and 100x

92 -{{code language="none"}}/FL1/Experiment/PG/ADQ412 GHz ADC/CH01/TD{{/code}}

106 -DOOCS prop : {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00/CH00.TD  or CH00.DAQ.TD{{/code}}
107 -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 ...
108 -DAQ channel: {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00{{/code}}

110 -in addition there are also additional parameters saved like:
111 -
112 -* sample frequency (in MHz)
113 -* error (state)
114 -* offset

118 -==== Struck SIS8300-L2D ====
119 -
120 -There is one in each of the MTCAs in the hall: MTCA-EXP1 at PG/BL1, the other at BL2 and BL3.
121 -
122 -They are 16 bit, 10 channel, 125 MS/s ADCs.

129 -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).

131 -Here is a trace of the first signal, a 1 MHz trigger connected from the x2timer board in the same MTCA:

137 -==== Using the Struck SIS8300-L2D to detect only integrated values of pulses ====
138 -
139 -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:
140 -
141 -* Peak height: from what signal on (incounts) is the signal to be counted as peak
142 -* 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
143 -* 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.
