Title: Help: Problem DDS to Hantek 6074BD (Frequency Generator) [Print this page] Author: rafaelholeva Time: 2024-2-7 16:45 Title: Help: Problem DDS to Hantek 6074BD (Frequency Generator) Hello, greetings!I recently purchased a PC USB Oscilloscope device from Hantek, model 6074BD. However, there are some bugs in the equipment when used in DDS (Function Generator) mode. When asking the DDS to generate a frequency of 1Khz, its output always shows half of this value, 500 Hz.
I believe it is a software or firmware problem;Note: I am already using the latest version available on the website V. 2.2.7
Another important detail is that in the equipment manual it refers to a function generator output impedance of 50 ohms. However, when measuring the function generator output it does not present 50 ohms. This implies a voltage error programmed by the software, which instead of showing 3.5 volts peak to peak, shows 7 Volts peak to peak.
To solve this problem, an impedance selection option via software and internal relay in the equipment would be necessary.
That's it for the moment, I would like to know if there is a solution to my problem, any firmware or software update that can solve this problem!
Thanks

Could anyone be so kind as to make the updated firmware and FPGA available for the Hantek 6074BD USB Oscilloscope?
