Figure 4 shows the Link Control menu on the ESG. This menu is used for
channel configuration. Notice the effect of the channel power scaling on
the individual channel power levels when scaled to 0 dB.
After completing the instrument configuration, connect the RF Output of
the ESG 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 since the ESG does not support bi-directional protocol handling.
Placing the mobile phone in test mode allows it to process messages with-
out full handshaking.
A vector signal analyzer display of the one-box example is shown in
Figure 5. This display illustrates that the code domain power levels shown
on the ESG after power scaling match those shown on the vector signal
analyzer.
[Center Frequency = 900 MHz, Mode = cdmaOne, Measure = Code Domain, Avg Frames = Off, PN Offset = 0 x 64,
Sync Type = Even Sec (Rear Trig In), Freq Ref = Ext]
