UNI-T UTS3021B Spectrum Analyzer

1. Key Specifications

• Frequency Range: With a measurement range from 9kHz to 8.4GHz, it provides extensive frequency coverage, making it suitable for various frequency – related tests across multiple industries.
• Resolution Bandwidth (RBW): The RBW ranges from 1Hz to 3MHz. This wide RBW range allows users to precisely adjust the measurement bandwidth according to the specific characteristics of the signals being analyzed, ensuring accurate results.
• Phase Noise: A phase noise of -98dBc/Hz @10kHz ensures high – quality signal measurement with reduced noise interference, enabling accurate signal quality assessment.
• Displayed Average Noise Level (DANL): The DANL of -161dBm contributes to excellent sensitivity. This low noise floor enables the analyzer to effectively detect and measure weak signals, which is crucial for applications where faint signals need to be analyzed.

2. Analysis Features

• Scanning Points: The series offers up to 40,001 sweep points. This high – density scanning provides higher frequency resolution, making it easier to capture hard – to – detect signals and analyze the frequency spectrum in greater detail.
• Selectivity: It exhibits excellent selectivity with a strong signal resolution capability for adjacent unequal – amplitude signals. This feature allows for clear differentiation of closely spaced signals, enhancing the accuracy of spectrum analysis and signal identification.
• Detector Functions: Equipped with a variety of detector functions such as positive peak, negative peak, sampling, standard, average, and quasi – peak, the analyzer offers flexibility in signal detection. Users can choose the most appropriate detection method based on the nature of the signal under test.
• Advanced Analysis Modes: The UTS3000B series supports advanced analysis 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 features are essential for comprehensive signal quality evaluation in fields like communication and semiconductor.

3. User – Friendly Interface

• 10.1 – inch Touch Screen: The instrument features a 10.1 – inch TFT LCD multi – touch HD capacitive screen. This large – sized, high – definition screen supports quick menu settings and multiple gesture operations like dragging, expanding, and zooming on the trace. The intuitive human – computer interaction simplifies complex operations, providing users with a convenient and efficient operation experience.

4. Additional Features

• Removable Dust Mesh: It comes with a detachable dust filter. After a period of use, users can easily remove dust from the air inlet, which helps to ensure the reliability of the entire machine. This feature prevents potential issues such as short – circuits, burns, or fires caused by dust accumulation.
• USB Flash Disk Insertion: The ability to insert a USB flash disk enables easy data storage and transfer. Users can save measurement data, analysis results, and instrument settings for further processing or sharing, enhancing the instrument’s data management capabilities.
• EMI Pre – compliance Analysis: With optional components and near – field probes, the UTS3000B series can be used for EMI pre – compliance analysis. This feature helps users identify and rectify EMI defects in advance, effectively shortening the product development cycle.
