Code domain power relative measurement accuracy (IS-2000 R-
RC3 and R-RC4 only): < ±0.005 relative to total power for linear
code domain powers from 0.05 to 1.0

2000 R-RC3 and R-RC$ only): < ±0.20 dB
Code domain results (IS-2000 R-RC3 and R-RC4 only):
Code domain power graph: displays the power in all 16 Walsh
coded channels (16 bit) for both the I channel and the Q
channel; reported power in each graph is relative to the total
combined I and Q channel power; red bars indicated active
channels, while yellow bars indicated inactive channels
Code domain table: displays the Walsh code, spread factor, code
domain power (at SF=16), total code domain power, and code
relative power to the R-Pilot channel for each active reverse
channel; possible active channels per IS-2000 include the R-
Pilot, R-FCH, R-DCCH, R-SCH1 and R-SCH2
Code domain power and noise graph: displays the power and
noise in all 16 Walsh coded channels (16 bit) for both the I
channel and the Q channel; reported power in each graph is
relative to the total combined I and Q channel power; red bars
indicate active channels, while yellow bars indicate noise in
each channel
Code domain measurement results: pass/fail indication based on
IS-98E standard specifications
Modulation quality measurement results: rho, frequency error,
time error, carrier feedthrough, phase error, amplitude error,
and EVM
Statistical measurement results: provides minimum, maximum,
and average for rho, frequency error, time error, carrier
feedthrough, phase error, amplitude error, and EVM when
multi-measurement mode is active; no statistical results are
available for any of the code domain power results
Concurrency capabilities: modulation quality measurements can
be made concurrently with all CDMA measurements that
support concurrency
