Chapter 9, Troubleshooting
Remote Operation Considerations and Recommendations
Changing from
ANALOG MEAS
Screen to CALL
CONTROL Screen
Measurements
When going from the ANALOG MEAS screen to the CALL CONTROL screen to
make a MAHO or Adjacent Channel Power measurement, you should wait
about.4 seconds (at cellular band frequencies) or .6 seconds (at PCS frequencies)
before querying the measurement.
Zeroing the Power
Meter With a PCS
Interface
The trigger mode retrigger must be set to “Repetitive” when zeroing the power
meter in the PCS Interface (
TRIG:MODE:RETR REP
).
Remember to set the
System Type
on the CALL CONTROL screen to
DCCH
and
set the
PCS Mode
field on the CONFIGURE screen to
On
before attempting to
zero the meter using the
CPR:DCCH:ZPOW
command.
Triggering to
Prevent Non-
recoverable
Firmware Errors
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.
Reducing Wait
Statements in Your
Program
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.
