Saelig Debuts New 20GHz Sig Gen
Compact signal generator.
Pittsford, NY — Saelig Company, Inc. has introduced APSIN20G, a new low-noise, ultra-fast-switching microwave signal generator covering a frequency range from 10MHz up to 20GHz. The unit provides micro-Hz frequency resolution, a wide and accurately-flat output power range to 30dBm, and very low spurious levels. Comprehensive AM, low-distortion, wideband DCFM, and high-speed pulse modulation allows for testing a wide range of receivers.

The signal generator's powerful trigger and sweeping modes can be controlled through 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. The 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 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.

The unit has a remarkably fast 200µs frequency switching time, as well as very low SSB phase noise. It 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. The signal generator incorporates an ultra-stable temperature-compensated 100MHz 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 extended to 100kHz. In addition, there is provision for attaching a USB power sensor.

The unit reportedly 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, measuring 172 x 220 x 106mm and lightweight at 6-lbs. (2.73kg) and will find applications in areas such as R&D low noise signal source, production testing; service and maintenance; signal simulation (Radar, WiMax, UWB); aerospace and defense (Pulse modulator, Chirps).
