W-CDMA
The W- CDMA set- up provides:
• Average power in a W- CDMA signal (bandwidth <=5 MHz)
• Peak power and peak- to- average ratio of the signal over a defined,
The measurement is a continuously gated measurement on a 3GPP
W- CDMA 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 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 10 ms
period is returned then re- initiated for the next 10 ms 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 WCDMA. Commands not listed are preset according to their
DEFault values (for further information refer to
