Tektronix Inc. has unveiled a line of compact RF and microwave power sensors/meters that feature what it boasts as the industry's fastest measurement speed. The Tektronix PSM RF Power Meter Series is fully calibrated throughout the entire operating temperature. The company added that this feature does away with the need for sensor zeroing and meter reference calibration.

The Tektronix PSM3000, PSM4000 and PSM5000 are compact USB power sensors/meters that can be used for many CW and pulse modulation measurements, depending on the model selected. The meters are delivered with Microsoft Windows-based power meter application software for controlling the meter, displaying readings and recording data. This combination provides a complete test solution, eliminating the need for a separate meter mainframe, described the company.

PSM Series

The PSM Series boasts -60dBm to 20dBm dynamic range.

Accurate power measurements have emerged as an absolute requirement in RF and microwave design and manufacturing. While testing of RF products has become faster and easier over the past several years, testing RF power still remains one of the most basic and time consuming tests. This has led to a market need for more capable, compact power sensors/meters such as the PSM Series, noted Tektronix.

The power sensors feature measurement speed rated at 2000 readings/s. This speed can significantly reduce test times and provide dynamic power measurement information, stated the company. A high-speed logging application provides a mechanism for getting this data into a host PC for analysis. The PSM Series products have a dynamic range from -60dBm to 20dBm and frequencies ranging from 10MHz to 26.5GHz.

The Tektronix PSM sensors use a patented technique to ensure stability and calibration over the entire temperature range. According to the company, this makes them more accurate over varying ambient temperatures than any other sensor on the market. Other power sensors require time-consuming disconnecting or zeroing and frequent calibration.

PSM3000 Series RF power meters provide true average power measurements, giving accurate power measurements independent of signal modulation and bandwidth, claimed Tektronix. The PSM4000 Series delivers average power measurements, and adds pulse and peak power measurements for gathering basic data on pulsed RF and microwave signals. PSM5000 Series power sensors/meters provide the same measurements as the PSM4000, and add pulse profiling capability for signal viewing and characterization in pulsed RF and microwave systems.

Tektronix PSM Series RF power sensors/meters are available for $2,590 MSRP.
