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 […]

Measurement Benefits of USB-Driven VNA

Measurement Benefits of USB-Driven VNA

Historically, test and measurement instruments have been developed primarily with their own operating systems. In fact, many late model conventional test equipment devices contain embedded PCs running Windows or Embedded […]

High Power Device Measurement with USB VNA

Measurement of High-Power Devices

Introduction The VNA output ports are capable of sustaining a pre-defined output power level as provided in the datasheet of the manufacturer. Exceeding the power ratings of the VNA ports […]
