Option H98 Product Overview
W-CDMA is a third-generation (3G) wireless technology designed to deliver high transport
capacity for high-speed data and low-cost voice services. The ESG-D Series Option H98
Signal Generator enables you to accelerate the development of W-CDMA base station and
mobile receivers by fully exercising the receiver to ensure it meets performance
requirements.
Option H98 provides real-time data on downlink or uplink signals.
•For downlink simulation, you can generate up to two coded channels (Perch 1 and 2,
plus one user-selected logical channel), and select the data pattern, symbol rate, long
code, and short code.Figure 1-1 shows the Option H98 downlink block diagram;
Figure1-2 on page1-3 shows more detail of the logical channels (Channel 1) with the
downlink state selected.
•For uplink simulation, you can generate up to three independent channels, or three
multicode channels, for sensitivity-testing needs.Figure1-3 on page1-3 through
Figure1-6 on page1-6 shows more detail of the uplink mode.
Typically better than 63 dBc adjacent channel power ratio (ACPR) performance, with less
than 1.25 percent error vector magnitude (EVM), ensures that the signal will meet
performance requirements for W-CDMA (seeChapter 2 for Option H98 specifications).
