CDMAone
The cdmaOne set- up provides:
• Average power in an IS- 95 cdmaOne signal (bandwidth is less than 1.5
• Peak power and peak- to- average ratio of the signal over a defined,
The measurement is a continuously gated measurement on a cdmaOne
signal. Its aim is to measure the peak and average power corresponding to
a <0.01 % probability that there are no peaks above the returned peak
reading. Time gating is therefore set to 10 ms, corresponding to 200000
samples. Triggering is set to occur continuously internally to the meter.
The internal trigger is set to AutoLevel. A reading over the 10ms period is
returned and the reading is then re- initiated for the next 10ms period. In
this way the reading always relates to a position beyond 0.01 % on the
CCDF curve and will refresh to track any signal or DUT changes.
The following table shows the power meter presets when <character_data>
is set to CDMAone. Commands not listed are preset according to their
DEFault values (for further information refer to
