Check Even-Second Clock

Overview

Most CDMA transmitter tests require an Even-Second clock signal from the base

 

station in order to correlate the measurement. If you are receiving an error stating

 

Cannot correlate to input signal. Check setup. , you may have a

 

problem with your Even-Second clock signal. This Software utility allows you to

 

check for a valid clock signal from the base station.
