APHSP-X Multi-Channel High Spectral Performance Signal Generator – up to 51 GHz

The APHSP-X is an agile and extremely low phase noise signal generator from 10 MHz (1 kHz with option 1K) to 12.75 GHz (APHSP12-X), 20 GHz (APHSP20-X), 40 GHz (APHSP40-X), or 51 GHz (APHSP50-X). It is available with 1 to 4 independently programmable and phase-coherent outputs. Excellent harmonic and spurious performance in combination with fast switching makes the instruments very well suited for high-performance demanding applications in labs or production facilities.

The key features are:

– Frequency ranges from 1 kHz to 12.75, 20, 40, or 51 GHz
– Low SSB phase noise: -139 dBc/Hz typ. at 10 GHz, 20 kHz offset
– Aging < 20 ppb per year
– Harmonics: -50 dBc, Spurious X-Band: -80 dBc typical
– Advanced pulse modulation ON/OFF: 100 dB typ., Rise time: 2 ns typ., Pulse width: 15 ns
– Fast switching speed of 3 μs (typ.)
– Single and multi-channel phase-coherent models

The applications include:

– R&D extremely low noise signal source
– Metrology-grade signal source
– Aerospace, Defense, Radar & EW
– Beamforming (generation of directional signals)
