The R4131D Spectrum Analyzer is small, light, and affordable. Its wide frequency range accommodates measurement of PCN MDS, and other 2 GHz band signals, plus harmonic distortion of RF signals. Maximum input sensitivity of -116 dBm, dynamic range of 70 dB, and -80 dBc phase noise characteristic enhance the range of signals that can be measured with the R4131D. AFC tuning enhances the stability of this economical spectrum analyzer. Built-in quasi-peak detector and EMC resolution bandwidth filters enable diagnostic EMC measurement. Automated measurements and data logging are complimented by a GPIB communication interface.
