Capabilities
The Option 200 single-ESG setup provides four fully coded 3GPP channels for use in
testing 3GPP mobile receiver designs.
Channel Types
The single-ESG setup can provide up to four of the following downlink channel types:
• primary synchronization channel (PSCH)
• secondary synchronization channel (SSCH)
• primary common control physical channel (PCCPCH)
• common pilot channel (CPICH)
• dedicated physical channel (DPCH)
• paging indicator channel (PICH)
• orthogonal channel noise simulator (OCNS)
A single ESG can provide a control configuration (PSCH, SSCH, PCCPCH, and CPICH) or
an information data transmission configuration (DPCH and PICH, with optional OCNS).
For valid channel type/channel number, see “Valid Channel-Type-to-Channel-Number
Assignments” on page 4-7. For valid channel combinations, see “Valid Channel
Combinations per ESG” on page 4-7.
Reference Measurement Channels
Option 200 provides reference measurement channels at 12.2, 64, 144, and 384 kbits per
second. This option also provides transport layer channelization for AMR 12.2 (adaptive
multi-rate) and UDI 64 (unrestricted digital information) protocols.
System Triggering and Synchronization
This configuration utilizes internal I/Q triggering. The rear panel EVENT 2 BNC
connector provides a system synchronization signal in the form of a chip-wide pulse that
resets the system every time a parameter change that requires system re-synchronization
is made. For increased measurement accuracy, the signal generator’s rear panel 10 MHZ
OUT frequency reference can be utilized by other instruments in the test system.
