100 kHz to 20 GHz Signal Generator APSIN20G

The APSIN20G is a low-noise and fast-switching microwave signal generator covering a frequency range from 100 kHz up to 20 GHz. The APSIN20G provides a mHz frequency resolution, a wide and accurately leveled output power range, and low spurious levels. It is targeted for applications where a high-quality CW microwave source with analog modulation is required. The APSIN20G includes AM; DC-coupled wideband-FM, PM, FSK and PSK, and fast pulse modulation as standard. Optionally, frequency chirps and programmable pulse trains get be executed. The APSIN20G 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. Available also as truly portable model with internal rechargeable battery module, this instrument offers a reliable and powerful alternative to expensive high-end microwave signal generators, where small size and excellent microwave performance at an attractive cost is required.
