Keysight Technologies has added two new models to its U8480 Series USB thermocouple power sensors. The range now comes with improved specifications, including an expanded frequency range to 67 GHz and a measurement speed of 900 readings/second.
The U8480 Series’ real-time measurement uncertainty feature significantly reduces overall test time by removing the need for time-consuming manual measurement uncertainty (MU) calculations. Users can now compute MU in real time and at any given point. The feature also allows them to display power measurements and their MU simultaneously, simplifying test measurement and increasing test accuracy.
The U8480 Series provides enhanced accuracy and repeatability with thermocouple sensing technology and a power linearity of less than 0,8%. The new S-parameter and gamma correction functions further improve measurement accuracy by correcting the mismatch errors caused by inserted components between the device-under-test and the power sensor, making the U8480 Series suitable for applications such as test system or instrument calibration.
Like all Keysight USB power sensors, the U8480 Series can be used as an accessory for other Keysight instruments, allowing these instruments to perform specific power measurement applications without needing to connect to a PC or laptop. The U8480 Series is compatible with Keysight FieldFox RF analysers and MXG signal generators, giving them power meter functionalities.
The power sensors also perform source power calibration with Keysight PNA, PNA-L and PNA-X network analysers. USB functionality and the bundled N1918A Power Panel software ease the measuring of high-frequency power measurements in applications ranging from high-volume manufacturing to calibration and field remote monitoring.
Also new to the company’s power sensor range, the E8486A waveguide power sensor, designed with a WR-12 flange connector, makes precise and accurate power measurements in the E-band spectrum of 60 to 90 GHz, making it ideal to meet the demands of E-band telecommunication applications.
The E8486A comes with an 80 dB dynamic range option, allowing the sensor to measure from -60 dBm to +20 dBm instead of the standard -30 dBm to +20 dBm range. With its expanded dynamic range, it continues to be highly accurate even when measuring low-level signals, making it possible to measure power at the receiver side of point-to-point transceiver modules in addition to the module’s output power.
For easy calibration, the E8486A incorporates a 50 MHz calibration port to eliminate the uncertainties due to temperature changes and the variance in making measurements with different meter and sensor combinations. It also offers excellent SWR of 1,06, minimising any measurement uncertainty caused by sensor and source mismatch for greater accuracy.
