| Review: Hantek DDS 3X25. Anyone own one? |

| Mechatrommer:
i have published my GolTek Controller software. its the first "almost" complete functionality, hence in alpha stage. i'm publishing to ask for alpha (or beta?) testers (hantek 3x25 owners everybody, even without hantek this program still can run in offline mode). i dont think its a good idea to publish the source code yet since i'm still under development, modification and update. but the software is working as it should, only bugs to find, with help from alpha testers, the bug fix process can be quicken as i'm still busy with the development. and its not meant for test tool only, its a real application i made esp for myself. except the help file system (details on specific technical terms) is not completed yet. i hope you can enjoy and benefit the software. cheers. Download Page - to download and install first for supporting files (esp CommDlg.ocx) Online Help Page - offline help is available in software file by clicking The Yellow GolTek name Main Page - my non realized plan yet features (just to make you tempted to download it) :P: 1] edit any ArbExpress csv wave file you like from other software (Tektronix, Hantek DDS3x25 software etc), load it in goltek controller and send to our awg 2] DUT impedance compensated display (info) 3] synch stable (and phase correction) feature (can be on and off) 4] force clock mode. to ensure whats in your csv file (clock and number of points) get feed into the hantek. again, a big thanks to marmad on this! 5] signal boost (to ensure max amplitude from down sampled data) yet to analyze the effectiveness 6] normal and log sweep (once, repeat, cyclic forward and reverse, like before) 7] flatness control and bandwidth limit. to ensure flat output from hantek (profile not good enough yet. online explanation on the concept not done yet. i'll asap) 8] 12 memory button to store and recall your favorite waves. 9] online (device connected) and offline live simulation of signal and synch, can help if you dont have enough dso channel to probe your signal or want to see if your signal in synch or not in online simulation. but dont trust it 100%, as i said i need alpha testers. 10] a rotatable knob! please tell me if its good or what. as usual, if you dont like it, dont use it. 11] near "true" awg hardware front panel interface, can be good for learning if you plan to get the "high end" one (can you guess from what awg interface i'm cloning it?) 12] lastly, beeps when send data to hantek :P (dont worry, can be turned on or off of course, default to off) hope to hear some suggestions. thanks Regards, Shafri. |

--- Quote ---i cannot read time div in you last picture so i cannot read its frequency? --- End quote --- Time div is 2.0ms - the frequency when the 'image' is snapped ist 900Hz - early in the sweep, which, as mentioned, was done using 4000points, 10 periods. But I JUST noticed for the first time that Sync Out is actually doing (almost) 2 pulses per 10 periods of the waveform - instead of one - like MPL5 is doing. Why the hell is that? |

--- Quote ---GolTek Controller --- End quote --- First impressions - very nice! Better than the Hantek software in many respects - except for the rotating knob ;) just kidding, don't mind knob as long as I have numpad input as well. One obvious display glitch (or not?) - bottom of controller (drawing) has large border (~100 pixels) of white hanging off it. I'll give it a thorough testing later with more time... and report back. Cheers - and thanks for your efforts! |
