The device is easy to talk to via 1 simple command character followed program data. All source code is sent on CD “saved as” using the latest version of Labview Basic. Labview is available with a free 1 month trial from National Instruments. If you want to write your own software, it is best to get Labview and reverse engineer the Windfreak Labview source code. If you don’t own Labview, you will also get an executable that will install standalone and run on a PC. This software was written in Labview and the open source code is included so that you can modify and enhance any way you see fit for your own use. Control is very similar to a bench top signal generator. It can control multiple devices based on programmed serial numbers, tune a RF CW frequency, run a RF sweep, Pulse Modulate, save many settings to EEPROM, and fine tune the PLL registers for experienced users. Please check out the SynthNV for more power and 1/2dB steps. There is a total of 10dB of output power adjustment in 4 total steps. RF power is controlled by two bits in the PLL chip.

(Check SynthUSBII firmware version, save to SynthUSBII internal EEPROM memory Frequency, Power, Modulation and Sweep setup for standalone operation. (Control some finer details of the ADF4351 chip to get higher accuracy or quality for a particular frequency.)Įxtras tab. Please see SynthNV for higher performance.)

(Minimum pulse size and resolution is 1mS. You may enter data either with the touch pad, knob, directly with the PC keyboard, and also by clicking on arrows next to the controls. Shown below, the software is eloquently engineered giving professional performance at fractions the cost of a bench top generator. Use this device as a generic RF signal generator in your test setup, or use it as a high quality local oscillator in your RF / microwave communication system.
