The 83570A Sweep Oscillator RF Plug-In is designed to be used in the 8350-Series mainframe, provides precision measurements to 26.5GHz. All solid-state, maintains a minimum leveled output power of 10 dBm, internally leveled to a flatness <±1.4 dB. At the output, power losses are minimized with a waveguide output connector (K281C coaxial adapter sold separately). The full range from 18GHz to 26.5GHz maintains a 30MHz frequency accuracy and 0.1% linearity. Output power has a calibrated range of 11 dB which can be extended with external attenuators (sold separately). Power level may be manually set to a 0.1 dB resolution, remotely programmed to a 0.02 dB resolution. With high frequency coverage, complete HP-IB programmability and outstanding leveled output power, the 83570A plug-in, combined with the many of the 8350 mainframe adds a new dimension to microwave measurements above 18GHz.
