Prerequisites
HSDPA is an extension of the WCDMA standard – that is why each HSDPA option is only available with the respective WCDMA option. The WCDMA options both require the 4479 Baseband Processing Hardware.
This page describes the final state of the HSDPA options. For the current state, please refer to the delta list for software version at hand.
4456 HSDPA Non-Call Mode Option
The non-call mode option provides basic signal generator and analyzer functionality. The signal generator generates a WCDMA or HSDPA signal either without data or containing basic data simulating a cell site (PCCPCH, PSCH, HS-SSCH; HS-PDSCH); supported modulation schemes are QPSK and 16QAM. The analyzer allows basic WCDMA and HSDPA measurements, i.e. output power, frequency error, modulation spectrum, Occupied Bandwidth (OBW), Adjacent Channel Leakage Ratio (ACLR), Spectrum Emission Mask (SEM) and transmit modulation (EVM and PCDE) with and without the HS-DPCCH being present. This option requires the 4466 WCDMA Non-Call Mode Option.
4455 HSDPA Call Mode Option
The call mode option provides the signalling part of HSDPA. The option supports the standard CS Attach, the Packet Domain (PS) Attach and the connection setup procedures based on different Reference Measurement Channels (RMC). Depending on the different needs for testing, the downlink signal can be configured as Fixed Reference Channel Handset (FRC H-Set 1 to 6), as a CQI channel or in a user-defined way. The option also supports the following transmitter measurements: maximum output power, HS-DPCCH power control, peak and RMS error vector magnitude, peak code domain error, spectrum emission mask (SEM) and adjacent channel leakage power ratio (ACLR). Tests on the receiver and receiver performance are covered by measurements such as data rate throughput (based on BLER), maximum input level for HS-PDSCH reception (16QAM), and CQI reporting. This option requires the 4467 WCDMA Call Mode Option.
