Brief Description The R&S®FSQ-K102 software enhances the R&S®FSQ and R&S®FSG analyzers for transmitter measurements on 3GPP Long Term Evolution (LTE) base stations. Analysis of MIMO transmitters provides more insight into the performance of the complete base station. The software analyzes the modulation quality, e.g. EVM or I/Q imbalance, of 3GPP EUTRA FDD signals in downlink. When combining two or up to four signal analyzers, these tasks can even be performed on MIMO transmitters. R&S®FSQ-K102 analyzes all LTE modulation types: BPSK, QPSK, 16QAM, and 64QAM. The user can define all bandwidths within a range of 1.4 MHz to 20 MHz.
Features & Benefits Large number of possibilities to determine the performance of the transmitter A summary of the transmitter performance is displayed in a table, providing a quick overview. As the LTE signals are highly complex (e.g. one frame of a 10 MHz signal may contain over 80000 different error vector magnitude results), graphical displays are more suited to quickly locate performance trouble spots in the transmitter. R&S®FSQ-K102 provides an abundance of graphical displays. Quick analysis of transmitter performance by controlling the demodulator After a performance problem has been identified, it is helpful in fault finding to change the settings of the demodulator. The captured data can be analyzed again, which ensures that any sporadic problem will be analyzed in detail as soon as it has been captured by the R&S®FSQ-K102 software. Spectrum emission mask and adjacent channel leakage power measurement included for ease of use R&S®FSQ-K102 includes all the settings to perform the spectral measurements required by the standard. The measurements are automatically configured by means of a few settings. Automate your measurement No matter whether R&S®FSQ-K102 is installed on the instrument or on an external PC, the measurements can be fully automated by using well-known SCPI commands. This makes R&S®FSQ-K102 ideal for use in automated test systems.''
