Specifications

Once the instruments have been properly configured, power

mapping must be performed to align the power levels of the

channels between the two ESGs appropriately. This is required

since the two ESGs are not aware of each other’s power level. To

perform power mapping, refer to the end of this section.

Connect the RF OUTPUT of ESG #1 to a signal analyzer to view the

signal, or to a CDMA mobile phone to establish communication. If

connecting to a CDMA mobile phone, protocol must be established

for call setup or the phone must be placed in test mode to allow it to

process messages without full handshaking.

Figure 8 shows the vector signal analyzer display of the two-box exam-

ple defined in Table 3 and Table 4 with the expected code channels as

follows:

Channel RC Data Rate Walsh Set Walsh Code

Pilot - - - 0

Sync - - - 32

Paging - - - 1

OCNS - - - 57

Fundamental RC4 9.6 kbps 128-bit 10

Supplemental RC4 153.6 kbps 4-bit 4

Note that the code domain power levels shown on the ESG after power mapping

match those shown on the signal analyzer.

[Center Frequency = 900 MHz, Mode = cdmaOne, Measure = Code Domain, Avg Frames = 10, PN Offset = 0 x 64,

Sync Type = Even Sec (Rear Trig In), Freq Ref = Ext]

supplemental traffic channel

at Walsh code 4 occupies

additional code space.
