PRACH transmit on/off power
Measurement method: The measure of the ON power of the PRACH preamble burst,
along with the OFF power preceding the burst and the OFF power following the burst
Input power level range:
–– ON power: –40 to +28 dBm/3.84 MHz
–– OFF power: –61 to –55 dBm/3.84 MHz
Input frequency ranges: 800 to 1000 MHz, 1700 to 1990 MHz
Measurement accuracy: < ±1.0 dB (typically < ±0.5 dB) within ±10 °C from the
calibration temperature
Nominal trigger range: Expected power ±9 dB
Temperature range: +20 to +55 °C
Concurrency capabilities: PRACH Tx on/off measurements cannot be made concurrently
with other measurements

Phase discontinuity
Measurement method: The measured results include the phase discontinuity (defined as the
phase difference of adjacent timeslots) as well as all waveform quality results for each timeslot
Input power level range:
–– Phase discontinuity: –61 to +28 dBm/3.84 MHz
–– Other measurements: –25 to +28 dBm/3.84 MHz
Input frequency ranges: 800 to 1000 MHz, 1700 to 1990 MHz
Phase discontinuity range: ±180°
EVM range: 0 to 35% rms
Phase discontinuity measurement accuracy:
–– < ±2.4° (typically < ±1.7°) for input levels of –25 to +28 dBm/3.84 MHz
–– < ±2.6° (typically < ±1.9°) for input levels of –51 to < –25 dBm/3.84 MHz
Other reported parameters with phase discontinuity: All measurements found in the
waveform quality measurement are also available; the specifications are the same in both
measurements, including the input power range of the waveform quality measurement
Measurement interval: 617 μs (= 1 timeslot (667 μs) – 25 μs transient periods at either side of
the nominal timeslot boundaries)
Measurement triggers: Protocol and external
Temperature range: +20 to +55 °C
Concurrency capabilities: Phase discontinuity measurements cannot be made concurrently
with other measurements
