Compact, ultra-agile frequency synthesizers with single- and multi-channel options

The FS1 series of frequency synthesizers offers fast switching speed, great phase noise, and high signal quality. Four models are available, with frequency ranges of 8 kHz to 20 GHz and 8 kHz to 40 GHz. FS1 frequency synthesizers come in a variety of form factors, including a flange- and rack-mountable module (AP4011A, single channel model), a compact desktop enclosure with color touch display and front panel control (AP4021A, single channel model), and a standard 1 HU 19” rack-mountable enclosure (AP4012A and AP4022A, multi-channel models).

  • Single- and multi-channel (up to 4) configurations.
  • Channels can be independently programmed in frequency, phase, and amplitude and are phase coherent.
  • Internal, high-stability oven-controlled crystal oscillator (OCXO) with external variable reference frequency input.
  • FM, PM, and pulse modulation
  • Fast frequency and list sweeps
  • USB, Ethernet, and optional GPIB communication ports (available for AP4012A and AP4022A)
