100 kHz to 12 GHz Signal Generator APSIN12G

The APSIN12G is a low-noise and fast-switching microwave signal generator covering a frequency range from 100 kHz up to 12 GHz. The APSIN12G comprises a full set of analogue modulation (AM, FM; PM, Pulse, Pulse trains, Chirps) while the APSIN20G-NM does not support any modulation and acts as a CW only signal source. With a 0.001 Hz frequency resolution, a wide and accurately leveled output power range, and low spurious levels, 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 200 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.
