Step 2. Using an ESG, setup a W-CDMA signal transmitting at 1.955 GHz and
−10 dBm.
Step 3. Select the channel analyzer mode and the adjacent channel power
measurement:
Press
Mode, Channel Analyzer, Adjacent Channel Power.
Step 4. Preset the analyzer.
Press
Mode Preset.
Step 5. Set the center frequency to 1.955 GHz:
Press
FREQ Channel, Center Freq, 1.955, GHz.
Step 6. Set the analyzer radio mode to W-CDMA as a base station device:
Press
Meas Setup, Format/BW, Format Type (List), Format List, select
W-CDMA (UMTS) using the up and down arrow buttons, press Select
.
NOTE To increase dynamic range, Noise Correction can be used to factor out
the added power of the noise floor effects. Noise correction is very useful
when measuring signals near the noise floor of the analyzer.
Setting
Noise Correction to On, will automatically set Sensitivity to Low.
If
Noise Correction is set to On, setting Sensitivity to High will
automatically set Noise Correction to Off.
