Pulse Measurement of a Power Amplifier

VNA 101 Bootcamp: Pulse Measurement of a Power Amplifier

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.

Time Domain Gating Measurements with a VNA

Time Domain Gating Measurements with a VNA

Time domain gating is a very useful tool in vector network analysis. If a measurement can be made over sufficient bandwidth, there will be ample resolution in the time domain to “gate out” reflections which are of no interest and obscure the desired measurement. It is helpful to first understand the time domain conversion process and then the simple manner in which chosen spatially defined reflections may be eliminated. Join us for this webinar where we explore time domain gating measurements with a VNA.

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.
