Showing or Hiding the OTA PN Scanner

---

The presence of the OTA PN Scanner at the top of your screen is the main distinguishing feature of an Over the Air measurement. If, from the main (Mode) screen, you selected [Tx Analyzer], then [1xEV-DO Analyzer], the OTA PN Scanner will usually be switched Off; if, from the main (Mode) screen, you selected [Over Air], then [1xEV-DO Over Air], the OTA PN Scanner will usually be switched On.

	Step	Notes
1	Press [Display]
2	Press [OTA PN Scanner]	Each time you press this key, the codogram state switches between On and Off.

When the OTA PN Scanner is turned Off, there is more space on the screen to display the Code Domain Plot, so the finer details of the Code Domain Plot are easier to see.
When you have the OTA PN Scanner display On, you also have the option of turning the CDP and Metrics Off. This leaves more space on the screen to display the OTA PN Scanner, so the finer details of the OTA PN Scanner measurement are easier to see. At the same time, most of the metrics are turned off so they appear as dashes on the metrics portion of the screen. Only the Frequency, the PN Offset, and the Time Offset are still computed and displayed on the screen. As the test instrument no longer has to compute the metrics results or the CDP plot, the update rate of the OTA PN Scanner is improved.
