Remote Operation Considerations and Recommendations
The following items discuss operation under HP-IB control. For much more
information on programming in the Call Processing Subsystem, refer to the HP
8920B Programmer’s Guide HP P/N 08920-90222.
Loopback BER
When making loopback BER measurements on the DIGITAL
MEASUREMENTS screen, configure the DTC settings on the CALL CONTROL
screen prior to switching to the DIGITAL MEASUREMENTS screen.
To Prevent
Problems When
Changing the
System Type
Changing the
System Type
field (on the Call Control screen) from
AMPS
to
DCCH
, and then immediately changing the
Cntrl Chan
settings, can cause the
Test Set to experience a non-recoverable firmware error (a “fatal” error requiring
you to turn the Test Set off and back on). This can be eliminated by either
querying the call processing status registers until the
Active
annunciator is lit
(recommended method) or by inserting a wait statement (of about 3 seconds) in
your program after the
System Type
is changed.
Temperature
Compensation
The CALL CONTROL or DCCH CALL CONFIGURE II must be displayed
before performing the temperature compensation using the
CPR:DCCH:ZPOW
command.
Handoffs
After establishing a call on a DTC, wait at least 1 second before handing the call
off to another channel. This helps eliminate the error “
Handoff message not
acknowledged by mobile
”.
Releasing a Call
After establishing a call on a DTC, wait at least 1 second before releasing the call.
This helps eliminate the error “
Release acknowledgment not
acknowledged by mobile
”.
Going from the
Data Display to the
Measurement
Display Mode
When changing the
Display
field from
Data
to
Meas
, you can get the error
“
Query UNTERMINATED
” if you query a measurement too soon. A wait of .2
seconds after changing the Display setting should eliminate this problem.
