Sweep oscillator applications are greatly expanded by the features of the popular 8350A Sweep Oscillator Mainframe. Along with the traditional swept and CW frequency functions the 8350A adds five markers with extensive capabilities, versatile data entry and complete HP-IB programmability. Accepts the 86200 (with adapter) and 83500 series of plug-ins for true versatility. Frequency range is dependent upon plug-in used (sold separately). Mainframe features also include the ability to save & recall up to 9 different front-panel settings! This is a very reliable mainframe that will provide years of quality service.
