13 -We have ADQ412AC-4G-MTCA digitizer cards for the experiment crates (Exp1, Exp2 and FL2Exp1):

15 -The cards are connected via Patch panels to the Experimental endstations and can be operated with a jddd panel:

21 -* **NOTE: between ADC and Patch panel we have installed an [[EMP protector>>attach:EMP_protector.pdf]] and an additional 1dB attenuator**

81 - ~* note that the sample rate is NOT locked to the FLASH repetition rate ! Thus there is a not integer number of samples between FLASH pulses. The sample rate also differs slightly from ADC card  to ADC card. The rough spacing is **1993.846** samples between 2 pulses at 1 MHz for details ask the local contact.

121 -== Amplifiers for the GHZ ADCs ==
122 -
123 -* **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.
124 -* The available ADCs 5x, 10x, 20 x 50x and 100x
125 -* The ADCs can be borrowed from Markus Braune
126 -* The Amplifiers fit perfectly to the dynamic range of the GHz ADCs - here a  [[ test of the Phillips scientific amplifier>>attach:Model_6954_Amplifier_Report.pdf]]
127 -* There are also [[BiasTs>>attach:ZX85-12G-S+.pdf]] available that can be borrowed  ([[link to internal page>>doc:FLASH.Bias T]])[[image:url:https://confluence.desy.de/download/attachments/177857419/20210414_161820.jpg?version=5&modificationDate=1618412745169&api=v2||alt="20210414_161820.jpg" thumbnail="true" height="250" width="333"]]

129 -== 108 MHz ADCs:  Struck SIS8300-L2D ==
130 -
131 -There is one in each of the MTCAs in the hall: MTCA-EXP1 at PG/BL1, the other at BL2 and BL3.
132 -
133 -They are 16 bit, 10 channel, 125 MS/s ADCs.  Here is a link to the [[Struck website>>url:https://www.struck.de/sis8900.html||shape="rect"]]

136 -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).
137 -
138 -Here is a trace of the first signal, a 1 MHz trigger connected from the x2timer board in the same MTCA:

143 -== Pulse energy server: 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 signal and integrates the samples around the peak.
146 -
147 -Things to set:
148 -
149 -* Min peak height: threshold fro which on some signal is considered to be a peak. The actual peak is then determined as the maximum of the counts after the threshold
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.
