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

@idpromnut which bits did you add to enable the HF counter? Did you have to add any silicon? |

But we hadn't performed a really high frequency test of the HF counter to be sure. I can at least now confirm that it is accurate up to 2.1Ghz (assuming my test equipment is reasonably accurate). |

I'm not sure what size/volt rating I should order. |

Hmm i didn't need to install any caps. I will have a look at the board tonight, perhaps i missed those! EDIT: if they are needed, I would simply measure the voltage on the two legs of the crystal and get a cap rated for double. Also, the capacitance needed would depend on the crystal used. I used one of these: http://www.kyocera.com.cn/prdct/electro/pdf/xtal/cx3225sb_wl_e.pdf (mostly because that is what I could find and yes, it was a little tricky to get soldered into place ;) |

@FrankenPC: I forgot to include the BNC connector that I used: eBay auction: #300529921992 Beware though that this connector required a fair amount of filing-down of the mounting pins to fit correctly. It also had the BNC locking bits in the vertical orientation versus the horizontal as the rest. |
