The HP 355D VHF Attenuator is a precision variable attenuator designed for use in VHF and lower RF applications. It provides a wide attenuation range of up to 120 dB, allowing for fine control of signal levels in testing and measurement setups. Operating from DC to 1000 MHz, it is well-suited for laboratory, calibration, and communications work. Built with Hewlett-Packard’s signature rugged construction, the unit offers reliable performance and smooth adjustment. It features a 50-ohm impedance and supports a maximum RF power of 0.5 watts (CW), making it ideal for accurate signal attenuation in sensitive environments.
