Picture: VSWR bridges

VSWR bridges

A VSWR bridge (also known as a VSWR measuring bridge or standing wave ratio bridge) is a measuring device used to determine the standing wave ratio (VSWR) in radio frequency and microwave circuits.

Picture: ESD targets

ESD targets

An ESD target (electrostatic discharge target) is used in electrostatics to control and test electrostatic discharge (ESD). ESD-Targets are current sensing transducers to verify ESD-Simulators.

Picture: Adapters

Adapters

These adapters are ideal to avoid having to keep a separate cable for each connection option.

Picture: Attenuators

Attenuators

An attenuator is an electronic component that is used to reduce the power of a signal without significantly distorting its waveform

Picture: Terminators

Terminators

For correct termination of a signal while preventing reflections.

Picture: Transient limiters

Transient limiters

Device for the protection of spectrum analyzer or measurement receiver inputs when carrying out conducted noise measurements or other measurements where the input levels cannot be predicted with certainty or where accidental overloads may occur.

Picture: Wideband injection transformer

Wideband injection transformer

A broadband injection transformer is used in measurement technology to carry out stability measurements in the control loop.

Picture: 2-way power splitter/power combiner

2-way power splitter/power combiner

The 2-way power splitter/power combiner is used to split or combine an RF signal. It can operate in two main modes:

  • Power splitter: Here, an input signal is distributed to two outputs. This is useful if you want to send a signal to two different devices or circuits.

  • Power combiner: This combines two input signals into one output. This is useful if you need to combine two signals, e.g. for the antenna connection.

Picture: High Pass Filter

High Pass Filter

A high-pass filter (also known as a low-cut filter) is an electronic component designed to pass signals with a frequency above a certain threshold and block those with a lower frequency
