Abstract
Occupied bandwidth of emission is measured by ⁄2-method or method X dB using spectrum analyzer or measuring receiver and subsequent computer processing. For measurement simplification it is necessary to find the spectrum level of X dB, which corresponds to occupied bandwidth. The article examines the possibility of solution problem using SDR platform HackRF One on example emission of digital television.
