The S2VNA software developed by Copper Mountain Technologies’ (CMT) for its VNA product line can now be used to calibrate the power of LadyBug’s power sensors. The LadyBug’s power sensors can be connected to either or both the ports of CMTs Vector Network Analyzers (VNAs) to perform power calibration. In general, power calibration of the source is an important step as some measurements require an extremely accurate power level from the VNA. Using the power level obtained from the VNA through measurements, customers can decide whether the power level is suitable for further design and analysis or a re-design is required.
Secondly, power calibration helps observe any possible reflections, which will eventually help designers to adjust and design devices with appropriate power levels. This measurement also helps in providing customer or regulatory compliance to various organizations such as the NIST.
LadyBug True RMS Average Power Sensors deliver reliable, accurate power measurements for CW, Pulse, and modulated signals. These diode-based sensors feature a wide dynamic range and a great VSWR. The optional external triggering input feature can be used without any external components. Recorder and Trigger outputs are also available. LadyBug’s patented NoZero NoCal technology makes these sensors ideal for calibration systems, automated test stations and other embedded applications. The video below demonstrates how you can use LadyBug Power Sensors to perform power calibration using a CMT network analyzer.
Several CMT VNAs are available to perform power calibration for LadyBug’s power sensors (USB-based/True RMS) such as the LB480A and LB5944A, which operate over a wide frequency range from 1 MHz to 44 GHz. CMTs VNAs are 2-port network analyzers that provide measurements from 9 kHz to 20 GHz. Options to further extend the frequency range may be available depending on the model and availability.
