Concurrency capabilities
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 indicate active
channels, while yellow bars indicate inactive channels
Displays the Walsh code, spread factor, code domain power (at SF=16),
total code domain power, and code power relative to the R-Pilot channel
for each active reverse channel; possible active channels R-Pilot, R-RRI,
R-ACK, R-DRC, and R-TCH
Displays the power and noise in all 16 Walsh coded channels (16 bits)
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
Rho, frequency error, time error, carrier feedthrough, phase error,
amplitude error, and EVM
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
Supports concurrency with all other 1xEV-DO concurrent measurements
