Advantest R4131D Spectrum Analyzer
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.
