Using Mobile WiMAX Signal Analyzer
Performing auto measurements
The Auto Measure function of the JD780A series allows a complete signal profiling covering RF
characterization and modulation quality parameters of up to 10 different carriers, particularly useful on
an overlay architecture where base stations are transmitting in different frequencies.
The Auto Measure can be easily executed either by selecting a menu in the instrument or by running a
programmed scenario in the PC-based application so that the instrument automatically configure and
perform tests on every aspect of all the carriers.
Setting limit
You can set test limits for test item(s) in the auto measurement.
Procedure
1.
Press the
LIMIT
hot key.
2.
Press the
RF Test Limits
soft key, and then enable test limits as desired.
3.
Press the
PvsT Test Limits
soft key, and then enable test limits as desired.
4.
Press the
Modulation Test Limits
soft key, and then enable test limits as desired.
5.
Optional
. You can enable alarm sound that goes off if the measurement falls outside of the limit.
Toggle the
Beep
soft key between
On
and
Off
to enable or disable the beep sound.
6.
Optional
. Go to
SAVE/LOAD
> Save
, and then select
Limit
to save the limit settings.
See
“Using save” on page 31 for more information.
Setting measure setup
After configuring test parameters as described in the
“Configuring test parameters” on page 456, you
can continue your measurement. The measurement settings can be saved and recalled as a file. You
can also use JDViewer, PC application software to configure a measure setup, save as a file, and load
the file on to the instrument.
Procedure
1.
Press the
MEASURE SETUP
hot key.
2.
Toggle the
Configuration
soft key and select the configuration option:
–
Current
:
to let the instrumnet use current frequency (single carrier) and determine pass or
fail based on the instrument
’
s limit settings in Auto Measure.
–
Scenario
:
to run a test with a programmed scenario in JDViewer.
The Scenario menu becomes activated.
3.
To load a scenario, press the
Scenario
soft key, and then select a scenario file to load.
4.
Toggle the
Test Time
soft key and select the test time option:
–
Now
: to let the instrument run a test only once.
–
Schedule
: to let the instrument repeat tests as defined in the Set Timing.
The Set Timing menu becomes activated.
5.
To define a schedule for an auto measurement, complete the following steps:
a.
Press the
Set Timing
soft key.
b.
Press the
Start Time (HH:MM)
soft key.
