Introduction The Agilent Technologies multichannel CDMA per- sonality, Option UN5, is ideally suited for adjacent- channel-power (ACP) and code-domain power measurements for CDMA base-station and mobile component test for single and multiple carriers. This personality offers preconfigured settings for pilot, 9-channel, 32-channel, 64-channel, and reverse channel. For additional control of CDMA signals, a channel editor provides the power to define up to 256 Walsh-coded channels per carrier with selectable channel type, Walsh code, power, PN offset, and data. Four IS-95 filters are provided as well as user-defined FIR filtering. To test CDMA variants, the chip rate is selectable from 10 chips/ second to 20 megachips/ second. All these capabili- ties are combined with superior ACP performance to test high performance active components.
