HP 8341B

The HP 8341B is a used synthesized sweeper offering frequency coverage up to 20 GHz, designed to provide highly stable swept and CW signals for microwave testing applications. This unit has supported laboratory work in component testing, network analyzer stimulus, and general RF characterization, and it is offered here in working order for buyers who need a dependable wideband signal source. Its synthesized design gives it the frequency accuracy and repeatability that made HP sweepers a standard in microwave labs. Technicians and engineers use the 8341B to drive devices under test during amplifier, filter, and antenna measurements where precise frequency control matters. The instrument's sweep modes allow for efficient characterization across broad frequency ranges, reducing test time compared to manual point by point measurements. Its build quality reflects HP's engineering standards from this era, and many of these sweepers remain functional and accurate well beyond their original service life. This sweeper is appropriate for microwave test labs, calibration facilities, and RF component manufacturers seeking a proven, cost effective signal source for wideband testing. As used equipment, it may show cosmetic wear from its service history, but its core synthesis performance continues to meet the needs of many bench and production test setups. It offers a practical option for buyers who want established HP reliability without the cost of new microwave sources.
