HP 8657B Synthesized Signal Generator, 100 kHz to 2060 MHz

The HP 8657B offers excellent performance at an economical price. The low residual FM and excellent phase noise performance of these signal generators make them ideal for many in-channel and even out-of-channel receiver tests. The HP 8657B is a versatile signal generator offering a variety of features, such as extended frequency coverage up to 2060 MHz, pulse modulation, simultaneous and mixed modulation combinations of AM and FM, as well as a carrier phase adjust capability that allows you to characterize phase-sensitive devices. In addition, the HP 8657B offers a wide output range, +13 to -143.5 dBm with superior level accuracy of ±1.0 dB. Built to stringent quality standards, the HP 8657B will promote consistent, repeatable measurements every time.
