WebSep 9, 2024 · For example, when JT65 provides a SNRreportedJT65 = -16 dB, the actual SNR is, SNRFSKJT65 = -16 dB + 29.7 dB = 13.7 dB, a SNR that reflects FSK tone power level well above the noise floor that we can see on our panoramic spectral display and hear on our Single Sideband Band (SSB) transceiver. The same applies to JT9 communications. WebMar 1, 2002 · In this test, the single-tone was at 3 MHz offset, while the two-tones were at 3.00 and 3.06 MHz, so a DC IM2 output in dBVDC is being compared to a 60 kHz IM2 output in dBVRMS. The 60 kHz output is expected to be 3 dB higher as derived above. But in the measurement system, there is a low pass response that rolls off by 1.4 dB at 60 kHz.
