Agilent Technologies E4421B - Cdma2000 Multichannel, Multicarrier Personality, Option 101

19
cdma2000 multichannel,
multicarrier personality,
Option 101
Generate multichannel forward and
reverse link signals according to the
developing cdma2000 standard with
Option 101. These 1X or 3X chip
rate, direct or multicarrier spread
signals can be used for base station,
mobile, component, and subsystem
tests. A table based channel editor
maximizes flexibility.
Description
Option 101 is a firmware personality
built on the internal dual arbitrary
waveform generator (Option UND).
The firmware can be activated or
downloaded by purchasing a license
key for users who already own UND.
Key features
• Multichannel cdma2000 forward
and reverse link signals, either
1X or 3X chip rate
• Choose multicarrier or direct
spreading type in forward link
• HPSK spreading/modulation type
used in reverse link for IS95C
radio configuration
• Select from predefined channel
configurations or use the table
editor to fully configure a
cdma2000 channel configuration
per your requirements
• Forward link channel types include,
pilot, paging, synchronization,
fundamental code and
supplemental code channels
• Reverse link channel types
include, pilot, dedicated control
channel, fundamental code and
supplemental code channel
• Each channel can be set to a
separate code domain power level
• Baseband clipping; clip the
peak-to-average power of signals
before or after FIR filtering
Table editor features
The table editor allows you to:
• Modify the cdma2000 forward link
by choosing data rate, Walsh code,
power, PN offset and data pattern
for each channel
• Modify the cdma2000 forward link
by choosing data rate, power and
data pattern for each channel
• Use your own FIR filters or select
from predefined filters. Filtering
consists of Gaussian, IS-95, IS-95
modified ACP filters, Nyquist, and
root Nyquist
Multicarrier cdma2000
Generate up to 12 individually
configured SR1, SR3, or combination
of SR1 and SR3 carriers within a
15 MHz bandwidth. Adjust frequency
spacing and power offset of each
carrier to meet test requirements.
Baseband clipping
Reduce signal stress on power
amplifiers.
Clip the peak-to-average power of
signals before or after baseband FIR
filtering. Clipping may be applied
individually to I and Q or to the
composite I/Q vector.
The table editor allows you to modify cdma2000 forward and reverse links.
