Search for PN Offset

Steps	1	Connect the equipment as shown in figure 23.
	2	In the main menu, enter the Base Station Channel number for the transmitter
		being tested.
	3	Turn on your base station transmitter (pilot channel must be on).
	4	Scroll to and select Search for PN Offset and the Software will begin the
		search. The Software will search for the PN offset in segments, displaying a message
		on the screen to show which segment is being searched.
	5	When the Software has found the PN Offset, you should see a display of the offset:
		PN OFFSET = 24

NOTE:	When the Software finds the PN Offset, it will insert the value automatically into the Base
	Station PN Offset field on the main menu screen.

Notes

During the search, the following error message will often appear:

Cannot correlate to input signal. Check setup.

This is normal for the Search for PN Offset.

If the Software is unable to find the PN Offset, it will display the message:

PN OFFSET NOT FOUND

If you decide to abort (stop) the PN offset search, press the Main Menu (k5) key. There can be a delay of several seconds before you see the main menu display.

See the section on PN Offset in "CDMA Measurement not Correlating" in chapter 4, "Troubleshooting, on page 69.".
