1. ACPR specifications apply when the instrument is maintained within ± 20 to 30 °C.
2. This is rms power. Convert from rms to peak envelope power (PEP) with the following equation: PEP = rms power + crest factor
(for example, 3GPP test model 1 with 64 DPCH has a crest factor 11.5 dB, therefore at +5 dBm rms, the PEP = 5 dBm + 11.5dB = +16.5 dBm PEP).
