Time Domain Reflectometry Measurements with a Vector Network Analyzer
Time Domain Reflectometry (TDR) has traditionally been performed using a fast oscilloscope and a very sharp impulse or step type excitation. Reflections from the excitation are measured at the source […]
Vector Network Analyzer Measurement of S-Parameters in a Pulsed RF System
This video demonstrates how to make Pulsed S-parameter Measurements using a VNA.
Automatic Calibration Module Confidence Check
How many times have you completed a series of measurements to only later find them tainted by a bad cable? The Confidence Check feature of the Automatic Calibration Module (ACM) […]
Reflection vs Transmission Accuracy in Vector Network Analyzer Measurement
Why is it that Reflection measurements are typically only specified to -35 dB, while transmission measurements are valid to -85 or -90 dB or more? This is a common question […]
Trends in the RF and Microwave Industry
As technology keeps progressing, Vector Network Analyzers are doing the same.The development of compact and portable instruments, such as USB VNAs, provide a wide range of benefits that are changing […]
Remote VNA Measurements
How can I make a measurement with a USB vector network analyzer remotely from the operating computer? We often see this question from our VNA users and want to make […]
Multiport & Balanced Measurements with a VNA
When working with a multiport or differential circuitry application, a 2-port VNA might not be suitable for your measurements. In this scenario, using a 4-port VNA is more effective for […]
Fixture Removal from VNA Measurements
Embedding and de-embedding have proven to be the most accurate way to remove or add any additional circuitry. Vector network analyzers can make more accurate measurements if the de-embedding, embedding, […]
Automating Vector Network Analyzer Measurements
In some applications of network analyzers, it is necessary to automate the VNA measurements. This video reviews the COM and TCP interfaces that the vector network analyzer measurements can be […]
