P/L3 Statistical pulsed signal characterization Procedure

Objectives

Characterize the capacity of the RFI Monitoring system to detect pulsed signals by statistical algorithms.

Steps to follow

• Turn on equipment

  • Power supply
  • Signal generator

• Configure to desired parameters

  • Power supply
    • Set Voltage to 3.3V
    • Set current limit to 0.3A
  • Signal generator
    • Set output frequency to some IF Band frequency periodic pulsed signals

• Set up nucleo board and PC

  • Make sure the proper code is loaded into the nucleo board

• Make connections

  • Connect the power supply to the payload:
    • Vcc to PoL (RED)
    • GND to GND (BLACK)
  • Connect the DAC output to the DAC_In (GREEN)
  • Connect the ADC input to the ADC_Out
  • Load the IF Input with a 50 Ohm perfectly matched load.

  

  • Connect PC to ground (plug in the charger).
  • Connect necleo board to computer by USB.

• Power on power supply.

• Begin the measurements procedure

  • Run the flashed program in Debug mode.
  • Once the program stops at the breakpoint, collect the calculated mean and plot it in a data processing software like Matlab.

• Analyze the collected data.
