5.2.10 Measuring access probe output power
Access probe output power is one-time access channel output power that consists of
the pre-ample and the message. Nominal power offset of access channel output
power, initial power offset, power increment in continuous probes, number of probes
in one-time access probe sequence, and number of probe sequences in one-time access
attempt are measured in this section.
Measurement procedure
