The R4131 Series incorporates the performance of the already-popular TR4131 Series of 3.5 GHz spectrum analyzers and provides additional feature as well. These analyzers have measurement-conditions memory function which includes waveforms, an auto-recall function which recalls measurement conditions when power is switched on and other features to simplify operation. In addition to these features, these analyzers use the proven spectrum analysis expertise of ADVANTEST, with standard features of directly readable field strength measurements compensated for antenna calibration factor and quasipeak value measurements conforming to CISPR standards.
