Hantek Function Waveform Generator HDG3012B / HDG3022B HDG3000 Series
Akbar:
I am surprised that no one is talking about this function Generator, seems well-built and it being sold at a decent price. The biggest selling point for me over the more compact Uni-T function generator is that you don't need any PC software to make arbitrary waveforms
The file format the function generator uses is not CSV for some reason, but the file opens just fine in notepad++ or in Excel for editing, a few lines needs to be added to tell the function generator on what to do.
I am just posting this in case someone wants more information on it, below is some data I collected messing around with the PC Program for arbitrary waveform generation in demo mode
//File Type is hwf?? Opens in Excel and Notepad++
// First Line Defines Mode
//10 = Samples/s
//20 = Frequency Mode??
version,10
//Second Line is Unknown, Does not Change??
type,2
//Line 3 is the number of Voltage Samples
samples,64
//Line 4 is the Sample Rate
//It is Defined in Samples/s or Hz
sps,1000.000000
//Line 5 defines the Dynamic Range
//Amplitude is in Vp-p
//5 means +/- 2.5V
zoom,5.000000
//Afterwards the Voltage Samples are Given
//They are Read as per Sampling Rate
//Voltage is As 0.000 000 with 6 Decimal Points
Scratch.HTF:
The file format is HWF with the following format (although it is from a HDG2000 series, it should be the same for the HDG3000 series):
version,16 ; DAC resolution (bits)
type,2 ; Type ID
samples,600 ; Total Number of Samples
sps,250000000.000000 ; Samples Per Second
zoom,20 ; Vpp Range (1/4/20 for +/- 0.5/2/10 Vpp respectively)
div,1 ; Waveform Division/Segment (1-65536)
0.100000 ; Sample 1
0.100000 ; Sample 2
-0.100000 ; Sample 3
...
0.000000 ; Sample 600
Common to both Types: All Samples except the last are terminated with CR+LF.
Type 1: Samples are signed numbers from -32768 to 32767 representing 0.0003125V/0.0000625V/0.000015625V steps for the Vpp range of +/- 10/2/0.5 maximum respectively.
Type 2: Samples are rounded down to the nearest 0.0003125V/0.0000625V/0.000015625V step for the Vpp range of +/- 10/2/0.5 maximum respectively and only negative numbers include a negative sign.
Akbar:
It does look similar, but the version line for the program does not seem to be the DAC resolution, as it becomes 10 for the samples mode and 20 for frequency mode, in one of the files I had it in frequency mode, and it changed to 20 but the rest of them are in samples mode which have 10, this generator is 16 Bit as well so 10 shouldn't be its resolution. I don't know why there are these two modes in the Waveform program and why they are any different

I am considering buying the 80Mhz version but lack of review is whats keeping me from ordering one. BTW how does it perform?

looks like a rigol clone ??
