Multichannel cdma2000
personality
(Option 101, ESG-DP and ESG-D series only)
This personality conforms to cdma2000 specification
revision 8. Provides partially coded data for component test appli-
cations.
Spreading rate
1x (SR1), 3x (SR3)
IS-95 filter selection
IS-95
IS-95 with equalizer
IS-95 modified
IS-95 modified with equalizer
All are IS-95 compliant. “Modified” filters reduce spurious
emissions for adjacent channel power measurements.
Other FIR filters
Nyquist, root Nyquist
α = 0 to 1
Gaussian
B
b
T = 0.1 to 1
Custom FIR
Up to 256 coefficients
16-bit resolution
automatically scaled
Rectangle
I/Q mapping
Normal, invert
Clipping
Clip location
Pre-or post-FIR filter
Clipping type
|I+jQ|, |I| and |Q|
Clipping range
10% to 100%
(clip the modulation level to a
percentage of full scale.
A level of 100% equates to no
clipping.)

ually configured)
Frequency offset
(per carrier)
–7.5 MHz to +7.5 MHz
Power offset
0 dB to –40 dB
Forward link
Spreading type
Direct spread (DS), multicarrier
Pre-defined channel
configurations (partially coded)

9 channel, DS or
Multicarrier/SR3
Radio configuration 6
Pilot at 9.6 kbps, sync at 1.2 kbps,
three fundamental channels at
9.6 kbps, and four supplemental
channels at 153.6 kbps
User-defined cdma2000
Channel types

Walsh code
Pilot and sync have fixed codes,
Walsh 0 and 32. Other channels
have codes selected from specific
ranges depending on the radio
configuration chosen
