Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!
<< < (127/134) > >>
TurboTom:
Component values are:

C233, C234, C238 are 100nF/25V
C236, C237 are 1nF / 50V
R183 51Ohms
R134 120kOhms
D14 1SS226 (equiv. BAV99)
L27 RF-Choke 805

D4, R194 and U29 are not related to frequency counter and aren't populated on my HDG2002 either. Was the LMX5080 already populated on your board or did you assemble it? It would be funny if it was and all the cheap "chicken food" left off. So far, I've only seen it the other way round as it was on mine, everyting except the RF divider populated...

Cheers,
Thomas

Edit: Correction of values for C236 and C237

Thanks, TurboTom!
 I populated LMX5080 and BNC connector.
Thanks a lot !

Wow this this is garbage.   I'm so glad I did not buy one off ebay.   Thanks everyone for these discussions.  It really saves a lot of people money and time.

Off to buy the Rigol....

It may be crappy but actually, having "inherited" also Rigol DG4102, and comparing prices and performance between the two, I'm not so sure which money is better spent. Currently, I hardly use any real arbitrary functionality on any of the two and after hacking and calibrating the Hantek, it performs quite reasonably as a "standard" generator. As a clock for a stepper-driven pump or to evaluate a (lower) RF signal transformer, it performs pretty reasonably, especially with the latest firmware which sped up the incremental encoder considerably. The Rigol generator isn't without its flaws either and more than twice the price tag (see my post here https://www.eevblog.com/forum/testgear/any-update-on-rigol-dg4000-series-hacking/msg857122/#msg857122 ) .

I don't know how the "smaller" Rigol models compare or the Siglent AWGs but I guess you've always got to be prepared for some shortcomings. Maybe not if you spend the money for a Keysight but at least for me these would be too expensive for an instrument basically used for my hobby.

Cheers,
Thomas

Just to revive this old 3ad ....

TurboTom, you  forgot to mention that was necessary to apply a huge HW mode to turn the Hantek in a safe instrument, at least Rigol is OK out of the box under this aspect.

The value of the workmanship involved in this process is well over the cost of the "toy" and you still have a subpar device functionally wise.

To those are looking for a fair ARB signal generator i would suggest a Siglent 2042x, i'm working with it  (expanded to 100Mhz) from several months without any important glitch.

Maybe still Rust inside (maybe, actually i never opened it), but very good performance for the price, for sure it rounds circles around several similar priced instruments.
