Chapter 3 — W-CDMA/HSPA+
Signal Analyzer
3-1 Introduction
The WCDMA/HSPA+ signal analyzer supports the following measurement modes:
• RF Measurements
• Demodulator
• Over-The-Air (OTA) Measurements
Connect the instrument to any Node B/BTS for accurate RF and demodulator measurements.
The instrument can measure node B transmitter performance over the air or directly. To
measure a W-CDMA signal over the air, connect the appropriate frequency band antenna to
the
RF In
connector. To connect the node B equipment directly, connect the power amplifier of
the node B equipment to the
RF In
connector of the unit using a coupler or attenuator.
Note
The W-CDMA/HSPA+ Demodulator option demodulates both W-CDMA and
HSPA+ signals. Refer to the instrument Technical Data Sheet for option
availability.
Note
The maximum input damage level of the RF In port is +30 dBm. To prevent
damage, always use a coupler or high power attenuator.
