Re: FG085 doesn't output SQR waveform
Please check the duty cycle setting. It might have been set to 0 or 100. Pressing the '.' button (decimal point) will show you current duty cycle. Press again will allow you change it.

Re: Sending screen error
Do you know the amplitude of 1KHz signal for bus pirate? If it matches the scope reading then scope is good. The amplitude of test signal could be wrong.
You have checked the frequency of test signal. But correct frequency doesn't mean the amplitude is correct.

Re: Sending screen error
Thank you! I saw the video finally. For the issue I'd suggest you first check the scope with some DC source of known voltage (like a battery or regulated power supply). This is to verify that the gain/attenuation of analog channel is correct. If the gain is correct then reproduce the issue. Touch co...

Re: Sending screen error
Thank you for the effort! But it still said "video can not be found".

Re: Smaller frequency steps wanted.
Yes this can be done. Just lowering the DDS clock will increase frequency resolution. But modifying the operation interface will take some time. We are pretty busy currently. We will do it later if you are not in rush.

I am sorry we are unable to open Youtube from within China. Please email the file to jyetek@gmail.com. Thank you.
Re: Zeroes
Please upgrade M48 to the attached firmware 113-08502-052. This sets DAC output to +5V when frequency is set to 0.
Please try 113-08512-014 for M168. It should allow amplitude reach 0.

Re: Control FG085 from serial port
Updates:
1 ) New command for setting waveform was added. Document updated.
2 ) Fixed a bug that resulted residual output voltage even when amplitude was set to 0.
