Phase discontinuity (continued)
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) or 283 μs (0.5 timeslot
(333 μs) – 25 μs transient periods at either side of the nominal timeslot boundaries)
Measurement triggers: Protocol, external, and HS-DPCCH
Temperature range: +20 to +55 °C
Concurrency capabilities: Phase discontinuity measurements cannot be made concurrently
with other measurements
