Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!

>>could the HDG2002 generate sine wave about 25 MHz?
Out of the box -> no.
After modding -> yes.

So is it a similar data format like i.e. comma separated values (csv) or tab delimited values? Please, could you give an example of such a file (at least a header)? .txt format does not ensure its a proprietary data format. Thx!

fremen67 posted some waveform files here (see page 14 of this thread), so you can download one and check file format on your own.

Sorry, there's a mistake in my last post. The data format for HDG2000B is .hwf.
The content of this .hwf file is csv file format, and it's easy to compile data by software like excel.
Example
version,17
type,2
samples,128
sps,250000000.000000
zoom,20
0.004570
0.042962
0.074040
0.088665
0.108775
0.138026
...
First line 'version,17' stands for the file content format version is 17, no need to modify;
The second line 'type,2' stands for the record data type is floating point data, its range: -1 to +1 (corresponding voltage range: -0.625V to + 0.625V). When type is 1, the record data type is integer, range: -32768 to +32767 (corresponding voltage range: -0.625V to + 0.625V);
The third line 'samples,128' stands for waveform data points is 128 points;
The fourth line 'sps,250000000.000000' means sampling rate is 250000000hz, i.e. the interval between two points is 4ns;
The fifth line of 'zoom,20', means the waveform magnification is 20 times, effective numbers are 1,4,20, stands for the corresponding magnification for the voltage of waveform;
The rest lines, each line represents a waveform data.

Some fresh news:
-currently shipped HDG2002B have firmware version 1.00.2(140819.0) , PCB: 1004, FPGA: 12, Keyboard: 3, Kernel: Linux 3.2.35
-U25 place on PCB is not populated, so HF counter doesn't work and upgrade becomes more complicated
-system.inf is now located inside /config/root
-tcxo (or maybe OCXO?) is covered with cap / thermal insulation box
That's all for now. Now I need to find proper replacement for U25 :-//
What exactly is U25 marked? Is it a common HF divider?
