Optional cdma2000 1x EV-DO Demodulation
With this cdma2000 1x EV-DO option (which includes Rev A capability), the instrument can perform MAC code domain power, pilot, Rho, EVM, data modulation type identification and other cdma2000 1x EV-DO measurements.
Optional 1xEV-DO Over-the-Air Measurements and Scanner
The 1xEV-DO scanner adds two capabilities. First, it allows BTS maintenance personnel to find the “Sweet Spot” for over-the-air 1xEV-DO signal quality tests. This can now be done without taking the base station out of service, or even hooking up to the BTS. Second, it gives optimization and planning personnel the ability to troubleshoot coverage, interference and co-channel interference issues with an easy-to-use handheld tool.
This option automatically identifies the PN offsets for the ten strongest pilots and graphically displays their power level, timing error and Ec/Io. This option also measures pilot dominance and multipath power so users can evaluate their RF measurement environment.
Optional GSM/GPRS and EDGE RF and Demodulation Testing
This GSM/GPRS and EDGE measurement suite adds the capability to test EGPRS signals to the YBT250. It provides the user with the most important base station RF measurements. These measurements include RF power measurements for each time slot, Power vs. Time, EVM, Phase Error, Origin Offset, Carrier-to-Interference ratio and other EDGE measurements.
Optional GSM/GPRS/EDGE Scanner
The GSM/GPRS/EDGE Scanner adds two capabilities. First, it allows BTS maintenance personnel to find the “sweet spot” for over-the-air GSM, GPRS or EDGE signal quality tests. This can now be done without taking the base station out of service, or even hooking up to the BTS. Second, it gives optimization and planning personal the ability to troubleshoot coverage, interference and co-channel interference issues with an easy-to-use handheld tool. This option automatically identifies the channel, frequency, power, channel type, C/I and if a control channel, the BSIC, for channels in the selected range.
Optional TD-SCDMA RF Measurements
This TD-SCDMA option provides DwPTS power (pilot power), along with instantaneous and peak power readings for each downlink time slot. This critical setting affects the size of the TD-SDCMA cell. In addition, the option provides occupied bandwidth measurements.
Optional W-CDMA/UMTS/HSDPA Demodulation
This W-CDMA/UMTS/HSDPA option adds 3GPP Release 5 demodulation capabilities to the YBT250. It provides the user with code domain power, pilot and sync power, scrambling code, EVM overall, EVM for 16 QAM modulations, Peak Code Domain Error and other W-CDMA specific measurements. In addition, the option includes provision for measurement of Revision 5 signals using Transmit Diversity.
Optional W-CDMA/UMTS/HSDPA Scrambling Code Analyzer
This W-CDMA/UMTS/HSDPA option adds the capability to evaluate the cochannel interference from neighboring Node B base stations. This enables users to determine the effect of making changes to or adding a Node B base station to their network and to evaluate any changes which might contribute to pilot pollution.
W-CDMA Field Strength measurements are also available, enabling essential measurement of C-PICH (Ec) emissions.
The Modules and the Platform
The Tektronix NetTek analyzer platform is required for using NetTek modules and cards. The NetTek platform includes the display, power supply, CPU and battery compartments. Modules can then be attached to the back. Up to four modules can be attached at once. A variety of modules and options allows you to tailor the instrument to service the standards and interfaces in use in your network.
The modular design also means that the instrument can easily be upgraded. New measurements or standards can be added with software upgrades or with additional modules.
