In terms of bang for buck, it depends on what you need. This is not a professional tool by any stretch (although the EE at my work is thinking of picking one up for our lab). But for a hobbyist, i think it is great value for your dollar. |

I have no doubts on the future :) --- Quote from: tinhead on May 19, 2014, 11:57:44 am ---oh well, we don't know how the hardware really looks like on HDG2102B. Sure, DAC/FPGA/SoC/PSU are the same, but the important filter part might be different (i really hope it is different ..., and if not, well we will do something about) --- End quote --- |

I seem to have done something very bad... I tried saving the "status" under the utility menu. The save worked, but on the next reboot, it appears the display of the HDG2002 goes black after the splash screen and the hantek are briefly displayed. It can still output a signal, so I don't think it's totally borked, but yeah. So word to the wise, don't save the status of the function generator! Could someone send me a copy of their generator's files (I guess etc and /home/user and anywhere else I might need to poke around), or even better, if someone knows how to do a factory reset, that would be better. Thanks! |

It will restore your default factory settings |

I hadn't done anything "bad" to the filesystem or anything, I was just playing around with some of the menus (actually doing what they describe in the user manual >.<). And no luck, same behavior when I move the def.hsf file and reboot. The error I am getting in the console is something about the display widget destroy != NULL. Looks like a failed assert or something. |
