1xEV-DO forward setting range
[Carrier Edit sheet]
On the Carrier Edit sheet, set up the Modulation parameters for the single carriers (associated with carrier numbers 1 to 9) that consti-
tute the multi-carrier.
Display Setting range
Wave Data Length
Number of frames of the waveform pattern to be generated. Specify up to 4 frames. Specify 3 frames when generat-
ing
a multi-carrier.
Over Sampling Over sampling rate for waveform patterns. Set 4, 8, or 16.
Default All Restores the settings of all the single carriers to the initial values.
Carrier Select a single carrier to be edited from 1 to 9.
Carrier Parameters Copy
Specify a single carrier to which the settings of the currently-set single carrier are to be copied (copy destination).
Set Carrier 1 to Carrier 9 or All Carrier.
Copies the settings of the currently-set single carrier (the corresponding carrier number is displayed in Carrier) to the
Execute copy destination specified by Carrier Parameters Copy. The settings to be copied include the contents of the RPC/RA
CH Parameter screen.
Set the data rate and transmission slot for the single carrier to be generated from the following:38.4 kbps (16 slots)
QPSK, 76.8 kbps (8 slots) QPSK, 153.6 kbps (4 slots) QPSK, 307.2 kbps (2 slots) QPSK, 614.4 kbps (1 slot) QPSK,
Data Rate
307.2 kbps (4 slots) QPSK, 614.4 kbps (2 slots) QPSK, 1228.8 kbps (1 slot) QPSK, 921.6 kbps (2 slots) 8-PSK,
1843.2 kbps (1 slot) 8-PSK, 1228.8 kbps (2 slots) 16QAM, 2457.6 kbps (1 slot) 16QAM, Idle Slot
1st to 4th Frame Active
(1) / Idle (0)
Set traffic channel active/idle for each slot.
Set the traffic channel payload data.
TCH Data
All ‘0’: Sets the payload data to all 0.
All ‘1’: Sets the payload data to all 1.
PN15: Sets the payload data to a discontinuous PN15 sequence. PN15 is continuous within a frame.
Offset Index Specify the PN Offset Index of the single carrier to be generated from 0 to 511.
TCH1 to TCH4
Specify the MAC Index that is used for the scrambling sequence of the traffic channel and preamble Walsh cover by an
integer from 5 to 63.
Initial value of the linear feedback shift register used to generate the PN15 sequence when TCH Data is set to PN15.
Reg1 to Reg4 Set a hexadecimal number from 0 to 7FFF. The offset can be added to the PN15 sequence of each TCH by changing
this initial value.
Restores the settings of the single carrier currently set on the screen (the corresponding carrier number is displayed in
Carrier Default Carrier) to the initial values. The settings in the Carrier Parameters frame are restored to the initial values of the single
carrier.
RPC/RA CH Parameters Opens the RPC/RA CH Parameters screen used to set up the parameters of the RPC and RA channels.
Generates the waveform patterns of nine single carriers with the current settings. After clicking this button, the entire
Display Setting range
Frame Selects a frame for which the RPC and RA channels are to be edited.
Slot Selects a slot for which the RPC and RA channels are to be edited.
RA Bit RA bit of RA channel. Set 0 or 1.
CH Power Channel gain of MAC channel (relative value to pilot channel). Set from –40 to +40 dB.
RPC Bit RPC bit of RPC channel. Set 0 or 1.
ON/OFF Turns on/off each MAC channel.
Sets the channel gains of the RPC and RA channels in the currently-set slot collectively to the ratio expressed with a
Normalize fraction. The numerator of the RA channel ratio can be set from 1 to “denominator –1”. The denominator can be set
from 2 to 99.

RPC/RA CH Parameters sheet:
[Multi-carrier Composition sheet]
Generates a multi-carrier or single carrier waveform pattern from the single carrier waveform patterns generated in the Carrier Edit
Display Setting range
Spacing Sets the frequency interval between the carriers having the consecutive carrier numbers, from 1.20, 1.23, or 1.25 MHz.
Carrier Select
Turns on or off the single carrier that is used to generate a multi-carrier (or a single carrier, if only one single carrier
were turned with all the others turned off) in the single carrier generated in the Carrier Edit sheet.
Target RMS Range
“RMS” indicates the waveform pattern RMS value. Set the maximum value to “Max” when adjusting the waveform
pattern RMS value.
RMS Adjustment Value Sets the RMS value of the multi- or single carrier waveform pattern.
RMS Adjust
Converts a waveform pattern generated by clicking the Composition Execute button into a waveform pattern that has
an RMS value close to the value entered in RMS Adjustment Value.
