What is the CDMA Codogram display on the E7495A/B Wireless Base Station Test Set?

Codogram is a three dimensional display of Walsh code versus time versus code power. In the figure below, the vertical axis is time, the horizontal axis is Walsh code and code power is represented by color. Power settling, control and data channel stability are easily monitored with the Codogram display. This feature is available in option 200 (cdmaOne/cdma2000 analyzer) and in option 210 (cdmaOne/cdm2000 over-air test) with firmware release 2.1 or higher.
