This Application Note describes measurements compliant with the cdma2000® base station standard described in 3GPP2 C.S0010 / TIA/EIA-97 / ARIB STD-T64-C.S0010.The primary focus is on solutions for generating and analyzing cdma2000® signals. The special characteristics that make the selected signal generators and signal analyzers eminently suitable for this purpose are detailed, and remote control programming is demonstrated by a free of charge program.

This document presents a simple procedure for network analysis that is more cost-effective than the use of scalar network analyzers. It allows the accurate measurement of the transmission characteristics of filters, amplifiers and frequency converters over a large frequency and dynamic range. In order to reach very high measurement speeds, Rohde & Schwarz signal generators are operated in 'List Mode', and Rohde & Schwarz power meters are operated in 'Buffered Mode.' The required programming for the signal generator and the power meter is illustrated by excerpts from a Visual Basic program which is available, free of charge, upon request.

The R&S®FSMR3000 (hereinafter FSMR) is a three-in-one instrument incorporating a Measurement Receiver, a Signal and Spectrum Analyser, and a Phase Noise Analyser.This application note demonstrates the use of the FSMR, including the Cross-correlation option (R&S®FSMR3-B60), to measure the Phase Noise characteristics of a raw Signal Generator (R&®SMA100B).The Cross-correlation phase noise measurement improves sensitivity by 5 · log(n) dB, compared with measurements that do not use this option. For example, a measurement using 10 correlations, improves the phase noise floor by 5 dB.

This application note demonstrates the use of the Measurement Receiver to calibrate the signal output level of a Signal Generator.Calibration in this application is a two-step process.► The absolute output level of the signal source, at a fixed level, is measured using a thermal power sensor (e.g. NRP50T), which in turn outputs its reading to the FSMR.► Output power calibration over a wider dynamic range (to lower power) is performed by connecting the FSMR to the signal source directly, and sweeping the power of the signal source.The FSMR offers a nominal total measurement uncertainty of <0.015 dB +/- 0.005 dB per 10dB step. At 1GHz, the power measurement range covers -152 dBm to +30 dBm. It is this intrinsic linearity, that the accuracy of the calibration relies upon.Absolute power measurement uncertainty, for the NRP50T thermal power sensor used in this Application Note, is 0.040 dB to 0.143 dB.This process may be repeated at multiple frequencies. Calibration values are automatically stored and managed by the FSMR. Measurement frequencies for calibrations are stored, will be automatically recalled by the FSMR, by re-selection of those frequencies.

The R&S®NRP-Z power sensors from Rohde & Schwarz represent the latest in power measurement technology. They offer all the functionality of conventional power meters, and more, within the small housing of a power sensor. This application note serves as a coding guide for situations in which the R&S®NRP-Z power sensors are to be used in custom test and measurement software.
