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

<< < (6/134) > >>

Sounds like it's a doddle! Thanks mate!

...in fact it seems a bit of a "fail safe" as you could modify things without the reboot and if you screw it up it just clears... (Wish life was like that...  ;) )

A couple of questions:

- It looks like to the left of the serial header there is a spot for a DB9 + a MAX323-style chip?
- I see the SOIC-8 footprint on the bottom under the HF counter, any ideas what chip part # could go there? I had a look around and came up with this: http://www.micrel.com/index.php/en/products/clock-timing/clock-data-distribution/clock-dividers/article/21-sy10100el32v.html.  Just not sure what type of divider would be needed; this is of course only a /2 divider.

The 2 spots on the left of the UART header are for the lan option (RJ45 jack + H1102NL Magnetic). See attached picture with populated spots.

I also though about a frequency divider. It could be a 1/128 divider as the high frequency input could go up to 2.7Ghz and the low frequency input is still working at 25Mhz. Tinhead suggested a LMX5080 or a MB510 but the pinout to this footprint is strange: 1&8 are connected together (2.5v), 2, 3, 6&7 are grounded and 4&5 are not connected ... :-//

You can get it off eBay for around 250€ shipped.

Interessting news!

Quite a bargain when considering the hackability.

I wonder how the Waveforms look like. Do you maybe have a DSO and want to post some measurements here in the forum?

Right now, I'm also considering to buy one of there FG's. Spec's are really awesome.
