When it comes to high-performance spectrum analyzers, Uni-Trend’s UTS3000T+ Series and UTS3000B/T Series stand out as top choices for a wide range of signal analysis applications. Both series are designed to deliver precise and reliable measurements for professionals in fields like telecommunications, electronics, and RF testing. But what are the key differences between the two, and which one should you choose? In this blog, we’ll dive deep into the specifications and features of each model to help you make an informed decision.

UTS3000T+ Series: The High-Performance Choice

The UTS3000T+ Series is designed for those who need advanced capabilities, including the powerful built-in tracking generator. This feature allows the analyzer to generate test signals for devices under test (DUT), making it ideal for applications such as network analysis, signal source testing, and system calibration.

Key Specifications of UTS3000T+ Series:

• Frequency Range: 9 kHz to 8.4 GHz
• Resolution Bandwidth (RBW): 1 Hz to 3 MHz, adjustable
• Displayed Average Noise Level (DANL): As low as -161 dBm
• Phase Noise: -95 dBc/Hz (at 10 kHz offset)
• Third-Order Intercept (TOI): +15 dBm
• Spurious-Free Dynamic Range (SFDR): >100 dB
• Input Impedance: 50Ω (nominal)
• Pre-Selection Filters: Included for reduced out-of-band interference
• Sweep Time: <15 ms (Fast Sweep mode)
• Weight: Approx. 4.6 kg
• Display: 10.1-inch TFT LCD touchscreen with multi-trace display modes
• Interfaces: USB, LAN, GPIB for remote control and integration
• Tracking Generator: Built-in for network analysis and signal calibration
• Power Supply: AC 100-240V, <35W power consumption

Best For: The UTS3000T+ Series is perfect for professionals who require detailed signal analysis and advanced testing capabilities. The integrated tracking generator makes it the go-to model for network analysis, filter testing, RF component characterization, and antenna testing.

UTS3000B/T Series: The Flexible and Cost-Effective Option

The UTS3000B/T Series offers many of the same core capabilities as the T+ series but is more cost-effective and flexible. While it lacks the integrated tracking generator, it still supports the addition of a tracking generator as an optional feature, allowing users to customize their setup based on their needs.

Key Specifications of UTS3000B/T Series:

• Frequency Range: 9 kHz to 8.4 GHz
• Resolution Bandwidth (RBW): 1 Hz to 3 MHz, adjustable
• Displayed Average Noise Level (DANL): As low as -161 dBm
• Phase Noise: -92 dBc/Hz (at 10 kHz offset)
• Third-Order Intercept (TOI): +12 dBm
• Spurious-Free Dynamic Range (SFDR): >95 dB
• Input Impedance: 50Ω (nominal)
• Pre-Selection Filters: Available with the optional tracking generator
• Sweep Time: <15 ms (Fast Sweep mode)
• Weight: Approx. 4.5 kg
• Display: 10.1-inch TFT LCD touchscreen
• Interfaces: USB, LAN, GPIB for remote control and integration
• Tracking Generator: Optional for advanced users
• Power Supply: AC 100-240V, <35W power consumption

Best For: The UTS3000B/T Series is a great choice for those looking for a reliable spectrum analyzer at a more affordable price. It’s suitable for general-purpose signal analysis, and with the optional tracking generator, it can be upgraded for more complex tasks like network analysis and device testing.

Detailed Technical Comparison: UTS3000T+ vs. UTS3000B/T

Here’s a breakdown of the key technical differences between the two series:

Which Model Is Right for You?

Choosing between the UTS3000T+ Series and the UTS3000B/T Series largely depends on your specific needs and budget.

• If you’re working on advanced tasks like network analysis, filter testing, or need the tracking generator for signal source testing, the UTS3000T+ Series is the better choice. Its built-in tracking generator and superior dynamic range make it ideal for more demanding applications.

• On the other hand, if you’re looking for a more cost-effective solution and don’t need the tracking generator right away, the UTS3000B/T Series provides all the essential spectrum analyzer features. You can always add the tracking generator later as your requirements evolve.

Conclusion

Both the UTS3000T+ Series and the UTS3000B/T Series are excellent spectrum analyzers that offer reliable and accurate measurements for a variety of applications. The T+ Series is ideal for high-end, advanced applications, while the B/T Series offers flexibility and a lower entry price point, with the option to upgrade as needed.

Whether you’re testing simple signals or performing complex RF analysis, both series will deliver exceptional performance tailored to your needs.
