Low-Noise and Fast-Switching Signal Generator
Hands on workshop at APS
Comparison Chart (pdf)
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.
The Model 845-H is housed in a 3U 19” enclosure for standard rack mounting applications. This industrial package is well suited for commercial applications needing a stable high-end microwave signal generator. It offers a compact size, unusually high output power and excellent microwave performance. Custom or OEM versions available.
