I recently purchased a Hantek DSO2C15 on ebay. I see using the remote software that it has the Signal generator Hardware built in. I can turn on and off the sine wave, square wave and ramp through remote, so I know all the hardware is there. However, I cannot load any waveforms. Do you sell an upgrade Firmware or license key that will enable full Signal Generator Capabilities making it a DSO2D15?
