At the beginning of the build process the number of available CPU cores is detected ARB Toolbox PLUS will spawn up to eight parallel processes for steps that can be carried out simultaneously The build process will create several temporary files per CPU process in the system s temporary directory If the number of system resources is limited and errors occur during the build process parallel processing may be disabled using the following command line option no multi process The build process can be started at any time and repeated multiple times Existing target waveforms are replaced by newer ones 61 15 Capturing with the Spectrum Analyzer The spectrum analyzer capturing module records UO data using a spectrum analyzer and saves this data as a waveform file The module can be invoked via the context menu for a folder entry in one of the local file system browsers Before using the module you must configure the spectrum analyzer for use with ARB Toolbox PLUS This is done in the Instrument Configuration panel Menu Instrument Configure The spectrum analyzer is added in the same way as the signal generators are added VISA resource TCPIP FSQ26 200837 INSTR Firmware 4 65 User data D Once a spectrum analyzer is added to the instrument list it can be selected as a capturing source in the capturing module Trigger Slope Please see the instruments operating manual for valid settings The first pag

Lal S The measurement results obtained from the above settings are summarized in the table below Original Clipped PAR 10 5 dB 8 3 dB ACLR 71 dB 69 dB EVM lt 0 3 2 42 As a rule of thumb the pre filter clipping PAR should be selected such that it is about 1 dB below the target PAR The pre filter clipping characteristic is usually set to a soft characteristic while the target clipping model uses a hard characteristic The basic idea behind this approach is that the first clipping stage reduces the PAR significantly As a side effect spectral regrowth occurs that is filtered with the low pass filter block The side effect of the filter is that the PAR increases again The small number of samples that remain above the target PAR are removed in the second clipping stage Manual 42 14 The Waveform Composer Start the waveform composer module via the context menu for a folder entry or a composer settings file entry in the local file system browser The waveform composer provides powerful and versatile functionality for building complex multicarrier scenarios The main purpose of the composer module is to provide the user with a flexible way for arranging various waveforms in time or in frequency This is done by arranging waveform segments in up to 16 parallel tracks The final waveform is built by adding all waveform data from all tracks on one common time scale The tracks are provided as placeholders for waveform se
