SynthHD PRO Dual Channel Microwave RF Signal Generator
The Windfreak Technologies SynthHD PRO is a 10 MHz to 24 GHz dual channel software tunable RF signal generator and frequency sweeper controlled and powered by a device running Windows or Android via its USB port.
The SynthHD PRO’s dual independent channels can be configured to run as two different frequencies, or the same frequency with different phases. This allows its use in antenna beam steering applications or quadrature signal generation commonly used in image reject frequency conversion.
The SynthHD PRO also has nonvolatile onboard flash memory so it can be programmed to fire up by itself on any frequency, power, sweep or modulation setting (and combinations thereof) to run without a PC in the field. This makes for a highly mobile, low power, and lightweight solution for your RF signal generation needs.
Product Highlights:
- 10 MHZ to 24 GHZ in 0.1 Hz steps
- -40 dBm to +18 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 onboard which is Arduino compatible
- Complete Labview GUI executable and source code (pictured below) included with purchase
