The Importance of a Tracking Generator

A tracking generator is an indispensable tool for engineers performing frequency response analysis on components like filters, amplifiers, and attenuators. By providing a signal source that synchronizes with the spectrum analyzer’s frequency sweep, it allows real-time measurement of how a device reacts across its operating range. This capability is essential in verifying the frequency-dependent behavior of components, ensuring performance consistency, and optimizing system designs. Tracking generators are especially valuable in RF and microwave engineering, where precision is critical to maintain signal integrity and efficiency.

For example, a communications engineer developing a bandpass filter for a 100 MHz radio system can use the UNI-T UTS3021B or UNI-T UTS3036B spectrum analyzer with a tracking generator starting at 10 MHz. The synchronized generator provides a signal sweep across the filter’s range, while the spectrum analyzer captures the output response. This method allows the engineer to pinpoint frequency characteristics, like passband performance and roll-off, and make adjustments quickly. The precision offered by features like a resolution of 0.5 dB and output flatness within ±3 dB makes the tracking generator an ideal solution for ensuring devices meet stringent design requirements.

Why Engineers Should Enable the Advanced Measurement Kit

The UTS3000B/T-AMK option is a valuable tool for engineers working on applications requiring precise RF analysis, particularly in advanced fields such as 5G, radar, and satellite communication systems. With its ability to automate time-consuming calculations like adjacent channel power (ACP) and transmit frequency error, it eliminates the need for manual measurement setups and external calculations, saving significant time and reducing the risk of human error. This functionality is especially crucial when working at higher frequencies where signal behavior becomes more complex. By enabling these automated measurements, the AMK option ensures faster development cycles, improved design accuracy, and quicker compliance with industry standards.

For example, consider a satellite communication engineer tasked with optimizing the spectral efficiency of a high-frequency transmitter operating at 8 GHz. Without the AMK option, calculating channel power and adjacent channel power would involve configuring the spectrum analyzer to manually measure power across specified bandwidths, exporting the data, and performing complex mathematical integrations. With the AMK option, these calculations are performed instantly with one touch, delivering precise results and freeing up time to focus on optimizing the transmitter's performance.

The Benefit of Measuring Adjacent Channel Power (ACP)

One of the most common yet challenging measurements in RF testing is Adjacent Channel Power (ACP), especially at high frequencies. Engineers must carefully measure the power in a defined channel and compare it to the power in adjacent channels to ensure signal integrity and compliance with spectrum regulations. The process often involves extensive setup, multiple measurement sweeps, and intricate manual calculations to determine power ratios with sufficient accuracy. The AMK option simplifies this process dramatically by automating the measurement of Main Channel Power, Left Channel Power, and Right Channel Power, along with their relative ratios. This not only speeds up the testing process but also ensures consistent, repeatable results, which is critical for applications like 5G base station design or satellite uplink testing, where precision is paramount.
