22 -We have ADQ412AC-4G-MTCA digitizer cards for the experiment crates (Exp1, Exp2 and FL2Exp1):
23 -[[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]])
24 -The cards are connected via Patch panels to the Experimental endstations and can be operated with a jddd panel:

111 -DOOCS prop : {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00/CH00.TD  or CH00.DAQ.TD{{/code}}
112 -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 ...
113 -DAQ channel: {{code language="none"}}FLASH.FEL/ADC.ADQ.PG/EXP1.CH00{{/code}}

115 -in addition there are also additional parameters saved like:
116 -
117 -* sample frequency (in MHz)
118 -* error (state)
119 -* offset

123 -== Amplifiers for the GHZ ADCs ==
124 -
125 -* **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.
126 -* The available ADCs 5x, 10x, 20 x 50x and 100x
127 -* The ADCs can be borrowed from Markus Braune
128 -* 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]]

132 -== 108 MHz ADCs:  Struck SIS8300-L2D ==
133 -
134 -There is one in each of the MTCAs in the hall: MTCA-EXP1 at PG/BL1, the other at BL2 and BL3.
135 -
136 -They are 16 bit, 10 channel, 125 MS/s ADCs.

143 -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).

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

151 -== Pulse energy server: Using the Struck SIS8300-L2D to detect only integrated values of pulses ==
152 -
153 -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:
154 -
155 -* Peak height: from what signal on (incounts) is the signal to be counted as peak
156 -* 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
157 -* 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.
