Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

In RF testing, an essential attribute of every RF signal generator is the maximum output power it can supply to a device under test (DUT) while maintaining spectral purity and level accuracy. The ...

A small audio test generator is very useful for quickly tracing a signal through an audio unit. Its main purpose is speed rather than refinement. A single sine-wave signal of about 1 kHz is normally ...
