Every engineering lab bench needs a supply of handy test accessories—cables, adapters, attenuators, couplers, combiners, fil-ters, detectors, limiters, etc. This article describes several accessories that can be built quickly (and cheaply), yet they provide sufficient performance from DC to 100 MHz. This frequency range includes most audio, baseband and intermediate frequency circuits, as well as many RF applications from VLF through VHF.
