BB-IC Evaluation (continued)

The N4850A acquisition probe

captures the Tx traffic generated

by the BB-IC. The control packets

are identified by the logic

analyzer, decoded and displayed

on the logic analyzer using the

packet viewer. Debug and

validation of the configuration

and control functions of the

BB-IC/RF-IC interface are

accelerated by using these

capabilities.

The N4850A acquisition probe

captures the Tx traffic generated

by the BB-IC. The data packets

are identified and the digital IQ

data is extracted from these

packets using the signal extractor

tool. The digital IQ data is

analyzed by the 89601A vector

signal analysis tools running

on the logic analyzer. These

capabilities enable BB-IC

validation team to validate

that the digital IQ was properly

converted to DigRF v3 format. In

addition, the DSP algorithms that

generated the IQ can be evaluated.
