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).
Multitone and two-tone (Option 430)

Real-time phase noise impairments (Option 432)
Close-in phase noise characteristics –20 dB per decade
Far-out phase noise characteristics –20 dB per decade
Mid-frequency characteristics Start frequency (f1) Offset settable from 0 to 77 MHz
Stop frequency (f2) Offset settable from 0 to 77 MHz
