Microwave Signal Generator APSIN 20G
The APSIN20G is a low-noise and fast-switching microwave signal generator covering a frequency range from 10 MHz (optionally 100 kHz) up to 20 GHz. The lower limit can be expanded to 100 kHz by the optional frequency extension 100 kHz to 10 MHz.
The APSIN20G 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 frequency resolution.
The APSIN20G includes AM, DC-coupled, low distortion wideband-FM, PM, FSK and PSK, frequency chirp, and fast pulse modulation as standard. 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
The APSIN20G allows 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 APSIN20G operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) to ensure minimal drift, and can be phase-locked to almost any stable external reference in a range from 1 to 200 MHz
The APSIN20G support various standard interfaces such as USB-TMC, LAN, and GPIB.
