HP 8657A Synthesized Signal Generator, 100 kHz to 1040 MHz

The HP 8657A 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 8657A is a versatile signal generator offering a variety of features, such as 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 8657A offers a wide output range, +13 to -143.5 dBm, with superior level accuracy of ±1.0 dB. Built for reliability, the HP 8657A uses an all-electronic attenuator, which is backed with a five-year warranty to ensure that you will make consistent, repeatable measurements every time.
