6074BD Function generation options not available

abhishek6590

I have purchased 6074BD from aliexpress and installed 6000BD series software from hantek website.
But I dont get the DDS option in the software. Please help.

Sir, please upload some pictures and the serial number of your scope.

Here is the image of the software that does not provide me with DDS option.

I think factory had flashed the wrong firmware, or skipped the DDS part. Please help me with a solution. Can I upgrade the firmware?

The software you provided worked like magic.  One single click and DDS started working.  It appeared like it unlocked the DDS function.

Thanks.

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

Only the function for the entire generating function is known.  However, the coefficients for the g.f. start with x0 and proceed uniformly to x2k for some k.  How is the formula for the central element recovered?
