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 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.
