HP ESG-D Series: Option UN5 Multichannel IS-95 CDMA Personality

The HP ESG-D series of digital RF signal generators provide a wide range of digital modulation capabilities, in addition to a comprehensive feature set and excellent analog performance -- at an affordable price. Recent enhancements to the HP ESG-D series include multichannel CDMA testing capability. With this new capability engineers working on CDMA base stations and mobile equipment can now test devices under real-world conditions. Up to 256 Walsh-coded channels can be generated to qualify components under realistic, worst-case conditions - such as a fully loaded base station with interference from adjacent base stations. (This new capability requires option UN5 - multichannel CDMA personality, and option UND - dual arbitrary waveform generator).

[ Features ]

Generate multicarrier CDMA signals
Generate up to 256 Walsh-coded channels for basestation applications
Independently define channel type, Walsh code, power, PN offset and data for each specified channel
Easily setup your CDMA signal by selecting one of the five pre-configured channel configurations
Generate a pilot or reverse signal to test mobiles or their components
Test developing standards based on IS-95 CDMA by modifying the chip rate and defining custom filters
Define custom filters or select one of the four IS-95 filters

[ Specifications ]

Frequency Range:              250 kHz to maximum instrument frequency

Chip (symbol) rate:           1.2288 MHz, adjustable from 1 Hz to 10 MHz

Modulation:                   QPSK (forward) with Walsh and Short Code spreading
                              Offset QPSK (reverse) with Short Code spreading
                              of random data

Pre-Defined Channel Configurations (power levels per IS-97-A) 
Pilot Channel:                Includes IS-95 modified filter, with equalizer
9 Channel:                    Includes Pilot, Paging, Sync, 6 Traffic and IS-95
                              modified filter, with equalizer
32 Channel:                   Includes Pilot, Paging, Sync, 29 Traffic and IS-95
                              modified filter, with equalizer
64 Channel:                   Includes Pilot, 7 Paging, Sync, 55 Traffic and IS-95

Reverse Channel:              Includes IS-95 filter

All filters are IS-95 compliant. 'Modified' filters reduce spurious emissions for
adjacent channel power measurements.
