Here's an easy to use synthesizer that offers sweep, generator, and synthesizer modes. The 2230A Frequency Synthesizer covers frequencies to 1MHz and can be selected with 1Hz resolution. The 2230A also provides 0, 5, and 10 V square wave outputs. Selectable impedances include 150-ohms (200Hz to 1MHz), 600-ohms (200Hz to 300kHz), and 75-ohms.
