Definitions of the parameters saved are:
RX chain gain: This is the overall receiver gain error compared to expected value
in dB’s.
LNA mid gain error: This is the difference in LNA’s gain step compared to expected
value in dB’s.
LNA low gain error: This is the difference in LNA’s gain step compared to expected
value in dB’s.
AGC slope error: This is the gain slope error in the baseband analog AGC gain stages.
LNA bias error: This is the difference in the LNA maximum gain with full and half
bias current.
WCDMA RX Band Response Calibration
• A signal generator is needed and test signal applied into NMM-3’s RF test con-
nector.
• Calibration is started from the Phoenix menu:
Tunings/WCDMA/RX band response calibration
• Press “Start” then “Tune”.
• The calibration routine will define the signal generator settings for you.
• Set frequency and settings to defined values and allow the tuning to continue by
pressing “OK”.
