Additional Features: Wide frequency coverage: 100 kHz to 2060 MHz <35 ms frequency switching speed AM and FM capabilities ±1 dB level accuracy (typically ±0.5 dB) Amplitude offset and phase adjust capabilities The low residual FM and excellent phase noise performance of the Agilent 8657B signal generators make it ideal for many in-channel and even out-of-channel receiver tests. The Agilent 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, it offers a wide output range, +13 to -143.5 dBm with superior level accuracy of ±1.0 dB. Built to stringent quality standards, the Agilent 8657B will promote consistent, repeatable measurements every time.
