Saelig Debuts APSIN26G 26GHz RF Signal Generator

Battery-powered, ultra-stable, low-noise, fast-switching microwave signal generator with MHz frequency resolution and high power output

Saelig Company, Inc. (Saelig) has introduced the APSIN26G - a new low-noise, ultra-fast-switching microwave signal generator covering a frequency range from 100 kHz up to 26 GHz. It provides micro-Hz frequency resolution, a wide and accurately-flat output power range to +20 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.  

The APSIN26G’s powerful 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 for truly portable use. Advanced frequency synthesis with a fractional-N divider makes for low SSB phase noise and micro-Hz frequency resolution. The APSIN26G 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 while 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 APSIN26G features an industry-leading, remarkably fast 400us 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.

The APSIN26G also 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 250MHz. And there is even provision for attaching a USB power sensor.

The APSIN26G 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 (6.8 x 8.7 x 4.2") 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.

Swiss-made by AnaPico AG, a leading-edge designer of RF sources and sampling systems, the APSIN26G is available now from their USA distributor Saelig Company, Inc.
