Fast-switching signal generator reaches 20 GHz

Test & Measurement World Staff - October 20, 2012

Berkeley Nucleonics’ Model 845 microwave signal generator covers a frequency range from 10 MHz up to 20 GHz with frequency switching times of less than 200 µs, low SSB (single sideband) phase noise, and a wide output power range.

The instrument’s lowest settable frequency is 9 kHz with some reduction of maximum output power.

Using fractional-N frequency synthesis, the Model 845 keeps SSB phase noise to –108 dBc/Hz for a 10-GHz signal at a 20-kHz offset. Frequency resolution is 0.001 Hz. The Model 845 includes AM, DC-coupled wideband FM, PM, FSK, PSK, frequency chirp, and pulse modulation as standard. Three internal modulation sources are available, and all modulation modes can be combined.

Berkeley Nucleonics’ full line of RF/microwave signal generators offers a wide array of options to meet application requirements in research and development, production testing, service and maintenance, signal simulation, and aerospace and defense. Packaging options include bench, portable, rack-mount, and card-level OEM integration.
