====== How to use oscilloscope ======
Model: Siglent SDS 1104X-E or SDS1204X-E

===== Counter function =====
  * Function like scaler in the NIM modules
  * Go to Ultility -> counter 
    * Counter on source any of four channel
    * Mode: period, frequency, totalizer 
    * Slope

  * Can use trigger out signal for counting the coincidence rate
    * Signal out signal is falling, delay by around 5.5us
===== Trigger =====
  * Edge: negatie slop
  * Pattern: can be used for coincidence using AND/OR/ NAND/NOR


===== Connect through Ethernet =====
  * Cable connect to the local network
  * Go to Utility -> IO -> IP set -> Turn on DHCP, get the ip
