Table 3. ESG #1 instrument configuration for two-box setup
Setting Notes
[900 MHz] Set to the appropriate center frequency of the carrier.
[-40 dBm] Set to the appropriate amplitude desired.
On ALC is the Amplitude Level Control.
On
Normal
Std.
Ext Ensure that the BBG Data Clock is set to Ext.
Use the arrows to navigate to adjust the BTS
(Basestation Transceiver Station) Setup parameters.
IS95 w/ EQ Set Filter to IS95 w/ EQ for either IS-95 or IS-2000
17.5 Set delay to 17.5 chips to align RF with trigger.
[00000000001] The LC (long code) State may be set to 00000000000
[0] for no long code or to 00000000001 or another value to
seed the long code.
From the Link Control menu, setup the channels as
follows. Refer to Figure 4.
F-PICH (Forward Pilot Channel)
1
On
Use the arrows to navigate to adjust the Channel
[-7.00 dB] Setup parameters. Walsh Code for Pilot Channel is
fixed at 0.
F-SYNCH (Forward Sync Channel)
2
On
[-13.00 dB]
32 Walsh code range for Sync is 0 – 63; typically 32.
OCNS (Orthogonal Channel Noise Simulator)
3
OCNS OCNS is optional and can be used to generate ortho-
On gonal noise into the system. It may be used as fill-in
power so that the total relative power equals 0 dB.
[-3.46 dB]
[57] Refer to the Power Mapping Procedure for details on setting
this parameter.
4 F-PCH (Forward Paging Channel)
On
[-10.00 dB]
[1] Select a Walsh Code between 1-7 for Paging.
On
On For the two-box setup, the External I/Q input is used.
Ext I/Q
Note: If the Signal Polarity Setup menu is not available, this
step can be skipped.
Pos Confirm that the Clock Polarity is set to Positive.

After configuring the hardware appropriately for the two-box setup, follow the steps in Table 3 and Table 4
below to configure the instruments. Table 3 is for the configuration of ESG #1 and Table 4 is for the configuration
of ESG #2. Values in brackets [ ] are for example purposes only and the actual value should be determined by the
user. Hard key selections are indicated by Bold text. Note: The LC (Long Code) State and the PN Offset of both
ESGs must match.
