- Datasheet


The APSIN20G-1URM is a low noise and fast switching covering a frequency range from 100kHz to 20GHz.

The instrument 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-1URM 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-1URM operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) to ensure minimal drift, and can be phase-locked to any external reference from 1 to 250MHz.

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.

The APSIN20G-1URM is 19" 1U Rackmount compact packaging.
