Interactive Video: Calibrating a 2-Port VNA
Virtually interact with CMT’s software to complete a simulated calibration of a 2-port VNA.
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 […]

Automation Interfaces of Copper Mountain Technologies’ Network Analyzers
Introduction to the CMT Automation Interface Copper Mountain Technologies’ VNAs can be readily automated and there are numerous options for users who wish to do so. To help illustrate the different automation […]
Introduction to Using Databased Calibration Kits
Introduction Vector network analyzers need to be calibrated before measurements to ensure the most accurate measurements possible are made. To do a calibration you need a calibration kit. The characteristics […]
Testing & Matching PCB Antennas
Introduction Connecting to an Antenna Under Test (AUT) integral to a Device (DUT) may involve some tradeoffs between measurement accuracy, electrical considerations, and mechanical ruggedness. In this paper, we describe […]
