README

  • These scripts are probably of little use to anyone given to their specific use for my testing. This is more for me to keep track of what I've tried
  • Keysight 6000-X series oscilloscope and up to 4 HackRFs are controlled via SCPI and hackrf_transfer respectively
  • Automation of phase offset measurements across frequency and different condition

NOTE

  • Issue noted in that the DC antenna bias on the HackRF is asserted for ~100ms at start-up. This is enough to trip the 50 ohm input of the scope. Issue has been noted in #1006, no fix found yet that doesn't include a DC blocking filter or removing the bias FET.
