    The APSIN20G is a low-noise and fast-switching microwave signal generator covering  a continuous frequency range from as low as 100 kHz up to 20.4 GHz with a 0.001 Hz resolution. 


    The APSIN20G is a wide and accurately levelled output power range and high spurious suppression. Advanced frequency synthesis with fractional-N divider makes for low SSB phase noise and micro-Hz resolution. Power level extension is available to accurately level below -90 dBm. 

    Two models of the APSIN20G are available: the APSIN20G and the APSIN20G-NM. The APSIN20G comprises a full set of analog modulation while the APSIN20G-NM does not support any modulation and acts as a CW only signal source. The APSIN20G includes amplitude modulation (AM), DC-coupled, low distortion wideband frequency modulation (FM), PM, FSK and PSK, frequency chirp, and fast pulse modulation with internal pulse train generator. Three internal modulations sources are available. All modulation modes of the APSIN20G can be combined. This allows the generation of complex modulation signals for modern communication and location systems. The combination of pulse modulation and FM simulates Doppler effects or chirp signals. Simultaneous AM and pulse modulation provides the types of signal occurring in pulse radar applications with rotating antenna. The combination of FM and AM can be used to check fading effects of FM receivers. 

    Both APSIN20G models allow fast analog and digital sweeps including flexible list sweeps, where frequency, power and dwell times can be set individually. A flexible triggering capability simplifies synchronization within test environments. The APSIN20Gs operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) to ensure minimal drift, and can be phase-locked to any stable external reference in a range from 1 to 200 MHz. Additionally, optimum phase synchronous signals can be achieved by feeding a 100 MHz reference directly as reference. 

    The APSIN20Gs support various standard interfaces such as USB-TMC, LAN, and GPIB.  It is targeted for applications where a high-quality CW microwave source with versatile modulation is required. It offers an alternative to expensive high-end microwave signal generators, where small size and excellent microwave performance at an attractive cost is required.
