SynthHD Software GUI (Labview source code included with purchase)


The following video shows the SynthHD 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.
