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- 26):
