NOTE
You can use the LIMIT hot key to analyze your measurements with the user-definable
limit and Pass/Fail indication. See "Setting limit for modulation tests" on page 317 for
more information.
Code domain power
The Code Domain Power (CDP) measures the distribution of power across the set of code channels,
normalized to the total power. It helps to verify that each code channel is operating at its proper level
and to identify problems throughout the transmitter design from coding to the RF section. System
imperfections such as amplifier non-linearity will present themselves as an undesired distribution of
power in the code domain.
Setting measure setup
After configuring test parameters as described in the "Configuring test parameters" on page 297, 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.
