Hello EF,
Yes I tried TTSource, the PC Software. It is very easy to build a waveform. You choose a frequency, draw with the mouse and download to the HDG. You PC acts as a remote control.
You can also edit each point and specify a value |O or you can also create a file (with Excel for exemple), save to an ASCII file with specific format (.hfw), import into TTSource and send to the HDG.
The format is simple ( a 6 lines header + 1 line/dot) but the way of defining the number of dots and the time each dot has to be repeated to achieve a defined frequency is not that trivial without documents. I will explain what I understood in later post.

It's not a connector but a bridge to connect the left side of the board with the right side.

Hi Dago,
The HDG 2002B is very nice to use. I find the GUI very intuitive for almost all the functionalities. What I don't like:
- There are to many freezes where the only option is to reboot (until you know what you should not do...)
- There is a build-in functionality for editing waveforms but I had no success to make it work (until now |O), even with files created on the PC. I also tried the RTFM option but it didn't work ;). It is too buggy or i am not smart enough... or both :). But it is so easy on the PC that it's OK for me.
- When remote controlling the HDG from the PC, the screen and the buttons states are not updated
Even with that, with the other functionalities the HDG is amazing !

This could be an interesting unit, I wonder what the specs on the OCXO will be.

Hi fremen67,
Is there any way / anywhere to get a download of the TTSource software? Likewise, anywhere to get a download of the manual?
On the connector, just to confirm, the slot I was asking about is to the right of the USB port an inch or two; next over on the front panel is a BNC connector that looks like it says count trig.
Also, what is the limit in terms of number of arb points that can be created and saved?
Thanks again, EF

You will find attached the chinese manual and a google translation of it in English.
I will try to post TTSource in other messages (I will split it with 7zip).

Sorry I got you wrong and was looking on the PCB :P. The 26 pins front connector is for digital outputs. I didn't used it at the moment.

TTSource allows you to work with maximum 67 108 864 points. You can save it (quiet long) but TTSource can't load it later on (1Gbyte file size).
When you enter your frequency, TTsource propose a number of samples and a sample rate divider. It tries to work with a number of samples around 6000 and adjust the divider to match the frequency. The divider goes from 0 (no divider) up to 249. The divider you enter will divide the sample rate by 4 times this number (the standard sample rate beeing 250Msamples/s). In fact the easiest way is just to enter your frequency, let the software calculates the number of samples and divider you need, draw your arb., download it to the HDG and enjoy ;)
The thing that confused me at the beginning is that the translation in the software for "Samples" is "Counter" and the translation for "Divider" is "Samole".. yes "Sample" with a typo ;). Anyway it is very easy to modify the language files.
I tried a 0.25Hz arb (1 004 016 samples!). It worked but took several minutes to be downloaded to the HDG. If you work with less then 10000 samples, it is downloaded in some seconds.
