ONFIGURE screen to On before attempting to zero the meter using the CPR DCCH ZPOW command Occasionally you may encounter non recoverable firmware errors resulting from timing conflicts between your program and the Cellular Adapter These conflicts are often caused by using immediate trigger commands that do not allow the Cellular Adapter enough time to complete a measurement before being queried To help prevent this problem use the default continuous trigger state whenever possible Wait statements are typically used to allow the Test System to finish the last requested operation before sending another command A much more efficient programming method is to use the Call Processing Status Registers to control program execution These registers monitor various call processing operations and indicate when a condition exists such as when a mobile has successfully answered a page and the Test Set is in the Connect state Using these registers you can write routines that cause the program to wait until a certain register indicates an operating conditions exists instead of entering some specific time period in seconds Refer to the HP 8920B Programmer s Guide for more information on using the Call Processing Status Registers S HP83206A USRGUIDE MANUALItrblesht fm Chapter 9 Troubleshooting Problems With or Without a PCS Interface Present Problems With or Without a PCS Interface Present This section deals with Test Systems that do not in
