Rigol DSA875-TG3

This used Rigol DSA875-TG3 spectrum analyzer with built in tracking generator is a practical instrument for RF filter design, amplifier characterization, and general educational lab use. The DSA800 series is popular among small labs, universities, and independent engineers because it delivers solid measurement performance at an approachable price point compared to higher tier brands. The integrated tracking generator adds significant value for users who need to sweep filters and passive components without a separate signal source. The analyzer covers a frequency range well suited to many common RF design tasks, and its clear color display makes it easy to interpret spectral traces during bench work. Many hobbyist labs, service shops, and smaller commercial test facilities have adopted the DSA800 series for tasks such as verifying oscillator output, checking spurious emissions, and performing basic EMI pre compliance checks. Its compact size also makes it convenient for mobile or field based measurement setups. Our team has verified this specific unit for power on function, frequency accuracy, and tracking generator output prior to sale. It is offered in good used condition and includes the standard power cable. This analyzer is an excellent choice for labs seeking dependable RF measurement capability without a large capital expenditure.
