IS-2000 measurement background
Prior to the introduction of the ESG signal generator’s Option 201
real-time cdma2000 personality, testing of IS-2000 mobile receivers was
performed in a limited fashion using custom solutions or non real-time
solutions such as arbitrary waveform generators.
Custom solutions had their downsides. They required significant time
and effort to develop, they were typically complex and costly, and they
provided only limited functionality and flexibility.
Arbitrary waveform generator solutions, such as the ESG Option 101
multi-carrier, multi-channel cdma2000 personality, have been used in
the early stages of IS-2000 development to facilitate receiver design and
test. Beyond the typical stimulus-response requirements of component
test, arbitrary waveform generators also have the capability to simulate
much of the coding required to verify receiver designs. Arbitrary wave-
form generators have been used to provide the first level of support in
receiver test to ensure that receiver designs are demodulating and
despreading properly.
The Option 201 real-time cdma2000 personality goes beyond these
solutions by offering a second level of support to receiver design and
verification. The added benefits of fully coded channels with complete
long coding, the ability to utilize user-defined data, and the ability to
make real time changes provide additional capabilities to accelerate the
design process.
