January 31, 2011 - Saelig introduced the APSIN20G - a low-noise, ultra-fast-switching microwave signal generator covering a frequency range from 10 MHz up to 20 GHz. It provides micro-Hz frequency resolution, a wide and accurately-flat output power range to 30 dBm, and very low spurious levels. Comprehensive AM, low-distortion, wideband DCFM, and high speed pulse modulation allows for testing a wide range of receivers. APSIN20G's trigger and sweeping modes can be controlled via standard interfaces such as USB-TMC, LAN, and GPIB, and can operate from an optional internal rechargeable battery. Advanced frequency synthesis with a fractional-N divider makes for low SSB phase noise and micro-Hz frequency resolution.
APSIN20G includes AM, DC-coupled wideband-FM, PM, FSK and PSK, frequency chirp, and pulse modulation as standard, and all modulation modes can be combined. This allows for the generation of complex modulation signals for today's advanced communication and location systems. The combination of pulse modulation and FM, for instance, can simulate Doppler effects or chirp signals; simultaneous AM and pulse modulation replicates pulse radar applications with rotating antenna; FM/AM combinations can be used to check fading effects of FM receivers. APSIN20G features a fast 200μs frequency switching time, as well as very low SSB phase noise. The unit provides 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. APSIN20G features an ultra-stable temperature-compensated 100 MHz reference (OCXO) to insure minimal drift, but it can be phase-locked to almost any stable external reference in a range from 1 to 200MHz. The lower frequency limit can optionally be expanded to 100 kHz. And there is even provision for attaching a USB power sensor. APSIN20G offers a reliable alternative to expensive high-end microwave signal generators, where small size, attractive cost, and excellent microwave performance with versatile modulation is essential.
It is compact (172 x 220 x 106 mm) and lightweight (6lbs) and will find applications in areas such as: R&D low noise signal source, production testing (industry-leading switching times; high dynamic range); service and maintenance, signal simulation (Radar, WiMax, UWB), aerospace & defense (Pulse modulator, Chirps), etc. APSIN20G is available now from $14,600.
