Test Plan Timeline RFDF

Test 1: Anechoic Chamber

Primary objectives:

  1. Verify that the KrakenSDR can pick up a 915 MHz signal in the anechoic chamber.
  2. Show the signal clearly in the spectrum.
  3. Maintain coherence/calibration across the five receiver channels.

Potential objectives:

  1. Compare performance of the Master and Slave Kraken.

1st Test Plan

Test Setup What to record Pass criteria
Baseline Kraken on, transmitter off Noise floor / spectrum screenshot No strong unexpected signal at 915 MHz
Master detection Master Kraken, transmitter on at 915 MHz Peak frequency, signal level, SNR, screenshot Clear repeatable peak near 915 MHz
Master OFF/ON check Toggle transmitter OFF/ON Spectrum change Peak disappears OFF and returns ON
Slave detection Same setup, swap to Slave Kraken Peak frequency, signal level, SNR, screenshot Clear repeatable peak near 915 MHz
Slave OFF/ON check Toggle transmitter OFF/ON Spectrum change Same behavior
Comparison Same TX power, distance, orientation, settings Master vs. Slave signal level/SNR Both detect signal; differences documented

Master and Slave Kraken Comparison

Parameter Master Slave Difference
Signal peak ___ dB ___ dB ___ dB
Noise floor ___ dB ___ dB ___ dB
SNR ___ dB ___ dB ___ dB
Detected frequency ___ MHz ___ MHz ___
Detection stable? Y/N Y/N
