iDEN
The iDEN set-up provides:
– Average power in one iDEN training and data pulse
– Peak-to-average one iDEN training and data pulse
– Average power in a 90ms iDEN frame
The measurement is started by detecting the iDEN training burst—for example the
burst emitted by a mobile—using the internal RF level trigger. Time gating is used
to measure the average power in the following 15 ms (data pulse). Gate 1 is used
to measure this data pulse. The 90 ms frame is also captured to measure the
average power in the entire frame. Gate 2 is used to measure the 90 ms frame.
The following table shows the power meter presets when <character_data> is
set to IDEN. Commands not listed are preset according to their DEFault values (for
further information refer to Table 12-1):
