    The spectrum analyzer offers the ability to measure smaller signals using our digital IF filter, which allows for smaller bandwidth settings and reduces displayed noise levels. The DSA700 also distinguishes between signals with a frequency difference as little as 100 Hz. The DSA700 has the capability to monitor FSK signals with the 2FSK-DSA option. A complete spectrum analyzer for your low frequency signals and systems at an unprecedented price.


  • Distinguish two nearby signals clearly with 100 Hz RBW
  • Compare spectrums with different color trace
  • Read spectrum peak values with peak table function
  • Measure lower level signal with the preamplifier turned on


Rigol’s DSA700 series spectrum analyzer makes radio, IoT, and educational/hobbyist measurements more accessible than ever with value analyzers designed for lower frequency RF test. The DSA700 shares the popular mechanical package of the DSA800 series analyzer with a focus on measurements below 1 GHz.

  • The ability to measure smaller signals: on the basis of this technology, the IF fi lter enables smaller bandwidth settings, which greatly reduce the displayed average noise level.
  • The ability to distinguish between small signals by frequency: using the IF fi lter with the smallest bandwidth setting it is possible to make out signals with a frequency difference of only 10 Hz.
  • High precision amplitude readings: this technology almost eliminates the errors generated by fi lter switching, reference level uncertainty, scale distortion, as well as errors produced in the process of switching between logarithmic and linear display of amplitude when using a traditional analog IF design.
  • Higher reliability: compared with traditional analog designs, the digital IF greatly reduces the complexity of the hardware, the system instability caused by channel aging, and the temperature sensitivity that can contribute to parts failure.
  • High measurement speed: the use of digital IF technology improves the bandwidth precision and selectivity of the filter, minimizing the scanning time and improving the speed of the measurement
