Industry Insights

Small Form Factor SATCOM Solutions

Application Note | Analog Devices

Traditional ground station satellite communication systems in the Ka-band have relied on an indoor to outdoor configuration. The outdoor unit includes the antenna and a block down conversion receiver that outputs an analog signal in the L-band.

What Is An RF Signal Generator?

Article | Berkeley Nucleonics Corporation

An RF signal generator is a device that behaves as a stable local oscillator signal, generating different types of modulated signals.

How To Use Antenna Factors

Application Note | A.H. Systems

Antenna factor (AF) is a comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. AF varies with frequency, that is, for the same presented field strength. But at a different frequency, the voltage produced at the connector is not constant.

Group Delay Measurements With Signal And Spectrum Analyzers

Application Note | Rohde & Schwarz GmbH & Co. KG

This application note provides basic information about the concept of a group delay measurement with spectrum analyzers and signal generators, and how this method simplifies the test setup and improves the measurement speed.
