UNI-T UTS3021B – Benchtop Spectrum Analyzer (9kHz – 2.1GHz)

• Frequency range: 9kHz – 2.1GHz
• Up to 40001 scanning points
• Resolution bandwidth (RBW): 1 Hz to 3 MHz, 1-3-10 steps
• Excellent sensitivity to test weaker signals
• Tracking generator (via option UTS3000B-TG) 

The UNI-T UTS3000B series are swept spectrum analyzers with a frequency range from 9kHz to 8.4GHz (model dependent). The chart below outlines main differences in each model.

The UTS3000B series provides up to 40,001 sweep points, providing higher frequency resolution, making it easier to capture signals that are difficult to detect.

Testing weaker signals can be challenging due to the inherent noise floor of the spectrum analyzer. The UTS3000B series features a Displayed Average Noise Level (DANL) as low as -161dBm, excels in sensitivity, enabling effective testing of weak signals. This capability is indispensable for applications where signal strength is minimal, such as monitoring low-power transmissions or detecting subtle signal variations.

UTS3000B spectrum analyzers can be used for EMI pre-compliance testing with option UTS3000B-EMI and optional UTS-EMI01 near field probes.

This turns the instrument into a powerful tool for identifying and addressing EMI defects in advance, shortening the development cycle and reducing the cost of compliance testing.

The advanced measurement kit offers an array of functions, including Channel Power, Time Domain Power, Occupied Bandwidth, Third-Order Intermodulation, Adjacent Channel Power, Spectrum Monitoring, Carrier-to-Noise Ratio, and Harmonic analysis. These functions are indispensable for in-depth signal analysis in various electrical engineering applications.
