Microwave Vector Signal Generator, Dual Channel – SynthHD PRO

The Windfreak SynthHD PRO RF Signal Generator is similar to the SynthHD but has these extra features:

  • Improved calibration for higher amplitude accuracy
  • Re-calibrate at the Windfreak factory when needed, or calibrate yourself
  • Milled aluminum case for better electrical performance and use in more rugged environments
  • SynthHD PRO will have 70uS frequency step time (as an option) and even higher amplitude accuracy in early 2017
  • CE certification
  • Easy stack-ability


  • 54 MHZ to 13.6 GHZ in 0.1 Hz steps
  • -50 dBm to +20 dBm (typical) in 0.01 dB steps
  • Set each channel to independent frequencies and amplitudes
  • 0 to 360 degrees coherent phase control in 0.01 degree steps on each channel
  • Stack multiple devices for coherent phase control on every channel
  • Select internal 10 or 27MHz reference or use external 10-100MHz reference
  • Pulse, AM and FM internal modulation including FMCW radar chirp
  • Pulse Modulation with 1uS minimum width and 1uS resolution
  • Pulse, AM and FM external modulation from DC – 10KHz
  • Powerful Trigger modes allow external triggering of most functions without a PC connected
  • Linear and list mode (frequency and amplitude hopping) sweeps include dual channel differential sweeps
  • Save all settings to the device for use without a PC
  • 32 bit ARM processor on board which is Arduino compatible (Teensy 3.2)
  • Digital schematics and complete Labview GUI executable and source code (pictured below) included with purchase
  • Top and bottom side PCB snap connector locations brings 20 power, analog and digital I/Os to your custom mezzanine boards
  • Windows, Linux and Android compatibility
  • Designed and manufactured in the USA with maximized value / cost ratio

SynthHD Pro Software GUI (Labview source code included with purchase)


The following video shows the SynthHD Pro doing a Pulsed FM Radar Chirp (FMCW) that is simultaneously AM modulated.

The video below is taken with both channels driven into a mixer. The mixer is then fed into an oscilloscope and displayed on the right side of the video. The signal shows the DC and near DC downconverted component. The DC level depends on the phase relationship between the two channels. The switch on the far right of the GUI toggles between controlling channels (RFA or RFB). For orders over 10 units discounts will apply. Request a quote here. Emails will be answered within 24 hours.
