Need help?Do you have a question about the Agilent Technologies U2000A and is the answer not in the manual?
The Agilent U2000 Series USB Power Sensors are a line of devices designed for precise power measurements in various RF and microwave applications. These sensors offer a convenient and portable solution for engineers and technicians, leveraging the ubiquitous USB interface for connectivity and power. The series includes several models, each tailored to specific frequency and power ranges, ensuring a suitable sensor for a wide array of measurement needs.
At its core, the Agilent U2000 Series USB Power Sensor functions as a highly accurate power measurement tool. It converts RF and microwave signals into a measurable electrical signal, which is then processed and displayed as power readings. The sensors are designed to provide true average power measurements, making them suitable for both continuous wave (CW) and complex modulated signals. This capability is crucial for accurately characterizing modern communication systems, radar, and other RF/microwave devices that often employ complex modulation schemes.
The sensors connect directly to a computer via a standard USB 2.0 interface, eliminating the need for a separate power meter mainframe. This direct connection simplifies the test setup, reduces clutter, and enhances portability. The USB interface not only handles data transfer but also powers the sensor, further streamlining operation. This design philosophy makes the U2000 Series ideal for field applications, educational settings, and benchtop testing where space and portability are key considerations.
The U2000 Series sensors are capable of measuring a wide dynamic range of power, from very low signal levels to high power outputs. This broad range ensures versatility across different test scenarios, from sensitive receiver measurements to high-power transmitter characterization. The sensors are equipped with various connector types, such as N-type and 3.5 mm, to accommodate different RF interfaces commonly found in test environments.
For enhanced functionality, the sensors can be integrated with Agilent's Power Analysis Manager software, specifically the Power Panel. This software provides a graphical user interface (GUI) that allows users to easily configure the sensor, view real-time power readings, perform statistical analysis, and log data. The software suite also includes programming guides, enabling users to automate measurements and integrate the sensors into larger automated test systems. This programmability is a significant advantage for high-volume testing and complex measurement sequences.
The U2000 Series also supports external triggering, allowing for synchronized measurements with other instruments or events. This feature is particularly useful in applications requiring precise timing, such as pulsed power measurements or characterization of time-varying signals. The trigger input typically has a standard impedance, though options for higher impedance are available for specific multi-instrument triggering scenarios.
The Agilent U2000 Series USB Power Sensors are designed with user convenience and flexibility in mind. The direct USB connection is a primary usage feature, offering plug-and-play simplicity. Users can quickly connect the sensor to any compatible computer and begin taking measurements without extensive setup. This ease of use is further enhanced by the intuitive Power Panel software, which provides a clear and organized interface for controlling the sensor and visualizing data.
Portability is a significant advantage of these sensors. Their compact size and reliance on USB for power and data make them highly suitable for field service, on-site troubleshooting, and mobile test setups. Various carrying options, such as soft carrying cases, holsters, and transit cases, are available to protect the sensors during transport and provide convenient access during use. These accessories underscore the sensors' design for practical, real-world applications beyond the lab bench.
The sensors offer a range of frequency and power options, allowing users to select the most appropriate model for their specific application. This modularity ensures that users can optimize their investment by choosing a sensor that precisely meets their measurement requirements without overpaying for unnecessary capabilities. For instance, models are available for general-purpose RF measurements, as well as specialized models for higher frequencies or extended power ranges.
Calibration documentation is an important usage feature, ensuring measurement accuracy and traceability. Agilent provides options for ANSI Z540 and ISO17025 compliant calibration test data, including measurement uncertainties. This documentation is crucial for quality assurance, regulatory compliance, and maintaining confidence in measurement results, especially in critical applications.
The U2000 Series sensors are compatible with a range of Agilent test equipment, including PNA network analyzers, spectrum analyzers, and signal generators. This compatibility allows the sensors to be integrated into existing test systems, expanding their utility and providing a consistent measurement platform. The ability to use the sensors with various instruments enhances their versatility and value within a comprehensive test environment.
For multi-channel applications or long-distance operation, the sensors can be used with Agilent's E5813A NETWORKED 5-PORT USB-to-LAN hub or commercially available active USB hubs. These accessories facilitate the connection of multiple sensors to a single computer, either directly or over an extended LAN cable, enabling synchronized multi-channel power measurements or remote monitoring.
Maintenance for the Agilent U2000 Series USB Power Sensors primarily revolves around calibration and ensuring the physical integrity of the device. Agilent offers comprehensive repair and calibration services to maintain the sensors' performance and accuracy over their lifetime. These services are performed by Agilent-trained technicians using factory calibration procedures, automated repair diagnostics, and genuine parts, ensuring that the equipment continues to perform to specifications.
The standard warranty for the U2000 Series sensors is 12 months, with options available to extend this warranty to 3 or 5 years. These extended warranty plans provide peace of mind and protect against unexpected repair costs, ensuring long-term operational reliability.
Calibration plans are also available, including Agilent Calibration Upfront Support Plans and Z540 or 17025 compliant calibration plans, with options for 3 or 5 years of coverage. Regular calibration is essential to maintain the accuracy of power measurements, as sensor characteristics can drift over time due to environmental factors, usage, and aging. These calibration plans help users adhere to their quality management systems and ensure the continued validity of their measurement data.
The robust design of the sensors, including their N-type or 3.5 mm connectors, contributes to their durability and reduces the need for frequent physical maintenance. However, proper handling and care, such as using protective caps when not in use and avoiding excessive torque on connectors, are recommended to prevent damage.
Documentation, including operating and service guides, programming guides, and power analysis assembly manuals, is provided with the sensors. These resources contain valuable information for troubleshooting minor issues, understanding the sensor's operation, and performing basic maintenance tasks. The availability of localized language versions of these guides further enhances user accessibility and support.
In summary, the Agilent U2000 Series USB Power Sensors are designed to be reliable, accurate, and easy to maintain. The combination of factory-backed repair and calibration services, extended warranty options, and comprehensive documentation ensures that users can depend on their sensors for consistent and accurate power measurements throughout their operational lifespan.
