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?

Thankfully no silicon was needed (as fremen67 has mentioned before). 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).

You mind giving me a hand with the 2 x 22pf surface mount caps?  I'm not sure what size/volt rating I should order.
idpromnut:
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 ;)
idpromnut:
@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.
