About:
Test bench setup is detailed here.
Replace the DUT (Amplifier2 is provided with this template) with an RF DUT that is 1.
suitable for this test bench.
For information regarding using certain types of DUTs, see RF DUT Limitations for
TD-SCDMA Wireless Test Benches (adswtbtds).
Set the Required Parameters 2.
Note
Refer to TDSCDMA_UpLnk_TX (adswtbtds) for a complete list of parameters for this test bench.
Generally, default values can be accepted; otherwise, values can be changed by the
user as needed.
Set CE_TimeStep.
Cosimulation occurs between the test bench (using ADS Ptolemy Data Flow
simulation technology) and the DUT (using Circuit Envelope simulation
technology). Each technology requires its own simulation time step with time-
step coordination occurring in the interface between the technologies.
CE_TimeStep defines the Circuit Envelope simulation time step to be used with
this DUT. The CE_TimeStep must be set to a value equal to or a submultiple of
(less than) WTB_TimeStep; otherwise, simulation will stop and an error
message will be displayed.
Note that WTB_TimeStep is not user-settable. Its value is derived from other
test bench parameter values; with default settings WTB_TimeStep= 97.65625
nsec. The value is displayed in the Data Display pages as TimeStep.
