Overview
The APSIN4010 is a low-noise and fast-switching RF signal generator covering a frequency range from 9 kHz up to 4000 MHz. Other APSIN models range to 2, 6.1, 12, or 20 GHz. The APSIN4010 includes AM, DC-coupled, low distortion wideband-FM, PM, FSK and PSK, frequency chirp, and fast pulse modulation with internal pulse train generator as standard. Three internal modulations sources are available. All modulation modes of the APSIN4010 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.
