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

Hey Marco - sorry I didn't noticed your inquiry the last time I checked this thread. Maybe it's a little late to answer, but better late than never. I checked the modulation schemes you requested and found all of them working exactly as they should. I attached a few screen shots of the waveforms on the scope. For the 20MHz carrier FM test I had to increase the modulation frequency to 50kHz and the deviation to 5kHz, otherwise I wouldn't have had a chance to visualize the modulation with my DS1054Z's FFT function. My spectrum analyzer is at home and I'm on work... ;) Actually, after playing around with a Rigol DS4102 generator which isn't without its flaws either, the Hantek (at least in the H/W - S/W configuration that I've got) doesn't seem such a bad choice, at least for "standard" waveforms. Cheers, Thomas |

Can anyone point me to the calibration procedure on this? When I select calibrate from the menu and then start, it asks me to input the voltage value from channel one into the hantek. I cannot get past this point. Even after entering the voltage (-560mV dc) I hit next but nothing happens. |

My HDG2002B sits in its cardboard box on my basement, i think forever thanks to Hantek's ridiculous / nonexistent aftermarket support. My suggestion for potential buyer is : stay away from this pile of crap. |

It's quite funny Hantek still seems to support this "pile of crap" 8) - there's a new firmware available for download on their web site http://www.hantek.com/en/ProductDetail_12_149.html I did the update on my toy, it now reports Software 1.00.3.03.07 (2016/04/11), Linux 3.2.35, FPGA 60 and keyboard 3. The software seems to be pretty stable now and most interestingly, the arbitrary functions (via the windows-based editor) work on channel 2, yet they don't on channel 1 (but no crashes so far). So maybe the generator is turning into something half-way usable after all ;). Unfortunately, the new firmware didn't address the shortcomings that annoy me most, namley the adjusted digit in incremental mode stays fixed relative to the decimal point which means when the units change (Hz to KHz for example), the increments that you control the value with suddenly change by a factor of 1000 -- CRAP! Maybe this won't have been the last update though... Cheers, Thomas |

I want to get my counter working. There are some missing parts on my pcb. I circled them in red. If you know their model, value, please, share it. Thanks! |
