ESG Option 201 IS-2000
Real-time receiver test setup
The Option 201 personality provides significant flexibility in its configura-
tion. It may be configured as a one-box IS-95 setup or as a two-box
IS-2000 setup. Since Option 201 is a real-time solution, it requires the
Option UN8 Real-time I/Q Baseband Generator for its operation.

Below
are descriptions of a one-box setup and a two-box setup with configuration
examples.

One-box setup
The one-box setup provides four IS-95 channels with real-time signal
generation capability. This setup may be used to test IS-95 receiver
designs. Figure 3 below provides the hardware configuration for the
one-box setup. Using an ESG signal generator with options UN8 and 201,
configure the hardware as shown in Figure 3. The one-box setup utilizes
internal I/Q triggering. EVENT 1 provides an even second clock with a
delay, which may be adjusted to align the frame timing with the RF output.
(Note: The delayed even second output provides a pulse every two
seconds and is used for synchronizing test equipment.) The 10 MHz
Out is used as a frequency reference for additional test equipment, if
needed.
