The Model 845-H is a high output power, low phase noise, fast-switching microwave signal generator covering a frequency range from 9 kHz up to 20 GHz. The Model 845-H provides leading edge output power up to +30 dBm along with a complementary range of features at a excellent price/performance ratio. It is targeted for applications where a high-quality, high output power CW microwave source with analog modulation is required. The Model 845-H includes AM DC-coupled wideband-FM, PM, and fast pulse modulation as standard. Programmable pulse trains and chirps are also available. The Model 845-H operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) and can be phase-locked to any external reference from 1 to 250 MHz.
