Webinar: VNA Impedance Measurement for Power Distribution Networks
Almost all modern circuits are sensitive to power quality, which to a large extent is a measurement of the power rail impedance. This is because flat impedance power rails result in much lower noise than power rails that aren’t flat. In RF circuits the peaks generally result in increased phase noise, while in digital circuits the issues are related to the allowed voltage window for the ASIC’s. In high-speed transceivers, these peaks result in jitter, which is also related to phase noise. In analog circuits, the peaks can result in increased noise density and in analog to digital converters the peaks result in spurious responses. The power rail impedance is typically controlled by the careful selection of bulk aluminum or tantalum capacitors, ceramic decoupling capacitors, inductors, and ferrite beads. The instrument of choice for these impedance measurements is a vector network analyzer and the most common and highest accuracy measurement is the 2-port shunt through technique, using a 2-port VNA. The VNA offers the excellent dynamic range and also wide bandwidth.

Benchtop VNA measurement of an RF Power Amplifier can be greatly facilitated by using a pulsed RF stimulus. If a continuous wave excitation is used, the PA may require a large heatsink and a fan to produce airflow. On the other hand, if the PA is measured with pulsed RF with a low duty cycle, the overall heat dissipation can be greatly reduced and heat-sinking may not be necessary at all.

Offset Frequency Measurements with a VNA
VNA Master Class: Offset Frequency Measurements with a VNA Webinar
A Copper Mountain Technologies VNA can make offset measurements where the stimulus and receiver are not at the same frequencies. This allows for the characterization of upconverters, downconverters, and mixers. Because the frequencies differ, phase measurement has no meaning and only scalar amplitude is determined. Vector mixer calibration utilizing a de-embedded reference mixer makes the stimulus and receiver measurements the same and allows for full amplitude and phase characterization of the mixer under test. De-embedding of the reference mixer requires a second-tier calibration. In this webinar, both of these methods will be demonstrated.

De-embedding Fixture Effects from VNA Measurements Webinar
Automatic Fixture Removal (AFR) is an intuitive software plug-in that is used to accurately measure hard-to-access devices, such as SMD-sized components mounted on a fixture by de-embedding the fixture effects. The AFR VNA software plug-in enables the measurement of a wide range of components through comprehensive methods tailored to specific fixture properties. It can be used for manufacturing and production facilities as well as for component testing.
The AFR software moves the calibration plane towards hard-to-access DUTs and guides the de-embedding process using either time-gating, filtering, or bisect methods on a 2-port 2xThru or 1xReflect fixture. These methods provide the user with better measurement accuracy and reliability based on the components being tested. The AFR software plug-in is easy to use and is compatible with all CMT 2- and 4-port Cobalt series VNAs up to 20 GHz and Compact series two-port, two-path VNAs up to 44 GHz.
During this webinar, we briefly demonstrate this using the software plug-in with the different methods available for de-embedding fixture effects. For more information about method selection, please read this application note.
