The APMSYN22 is a new compact-size broadband frequency synthesizer for the generation of accurate and stable signal in both CW and pulse form, covering a frequency range of 100 kHz to 22 GHz, with a fast-switching time of 5 µs (with option FS), the output power of -40 to 25 dBm. The phase noise at 1 GHz and 20 kHz offset is -132 dBc/Hz, and the subharmonics lower than -60 dBc. The frequency setting resolution is 10 mHz and for the power 0.5 dB.
The frequency synthesizer is excellently shielded and in a very compact module form, weighs lighter than 0.5 kg, consumes barely 17 W and therefore passively cooled. It features ETHERNET communication port for local and remote connection to a PC for control over GUI software or SCPI commands.
The microwave signal source features external reference support of 100 MHz and 1 GHz. Multiple units can be connected together, with one unit acting as the master and the others as slaves, to implement multi-channel PHASE-COHERENT sources. The Master reference frequency of 1 GHz is generated once in the master unit and looped through all the slave units. The phase coherence reached is about +/- 0.5 degree over 10 hours when all the channels are set to 5 GHz, as an example.
