Hallo,
I'm using DRS4 Evaluation Board Rev 4.0 and I'm trying to change the output of the samples to be an average of  #  measurements (1000 or even more)
during the process I have encountered some difficulties I hope you will be able to help me  with:

1. the DRS chip have 8 channels but the Evaluation board have only 4 channels. does the default mode of the DRS in the Evaluation Board is 1024 bins for each channel or 2048?

2. in the readout mode, does it samples all the 1024 bins waveform from a channel and then move to the next one, or after each bin it move to the next channel?

3. In the file "drs4_eval4_app.vhd", I have a problem finding the names of the signals that represents the registers bits which tell me what is the number of the bin (1-1024) the ADC is reading from the DRS, and the signals

that represents registers A0-A3. can you send me their names? 

4. In another matter- is the -0.5V to 0.5V is the  upper and lower  limit of the input (or just a working range), and if not what is the limit for AC?  is there a fuse on the board in case of overload from the input? (I didn't see  it in the User's Manual, but I didn't know if you will mention it there in case there is one).

thanks in advance and have a nice day,
