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

@ ippromnut:
Same DIY as yours ... but the FE5680 is not so bad (around -105 dbc PN @ 10kHZ that can be displayed by my best SA (improved YIG)).
I will add some tests with a 10MHz signal reference from an Agilent generator equipped a dual oven TCXO >10^-9.
idpromnut:
@RFasic: the second reference I tried was the OCXO from my HP 5334A, with similar glitchy results. That reference I am way more confident of. I will perform the same series of checks with the reference out (TCXO) on my HP 8642B.

I think this could be usefull for many people as it is easy to physically rotate the LCD (the lenght of flat ribbon seems to be sufficient for both configurations).

it is actully funny, you can't use lot of todays gears when then in-line with your eyes (or above). Hantek is here very conservative,
all their gears can be perfectly use like that (and i was always happy about, i don't have tons of place on desk, i like all my gear to have above it). Of course for people who have them all on their desk directly it sucks (are there any? i thought only maketing ppl have gears on desk directly, an EE have neverenought space for that). So if you really have need to place it directly on desk, then use that two feets on bottom side and move your gear 60-80cm away from you. Sure, you (maybe) can rotate the physical display to get "view angle for use on desk", but then you have to resolder i think two resistors on display itself to rotate the displayed information as well (check the datasheet, i think it is still Innolux AT070TN83).

Thank you Tinhead, you are right, I only need to switch the correct Vcc or GND signal on pins 39 and 40 in order to choose how to rotate ...
I have enough place on my working areas and often have to move those little equipment from one of them to another, and ... they are always placed on the working area near my right hand .... one of my oscilloscopes is a RIGOL DS1204B and the TN display is assembled the way i hoped, same thing with a R&S UPL and 2 Advantest SA. So I think that both display configurations are important .... but with the next (or next .. next) generation of equipement I hope they will generalize the IPS or Oled displays (... it a dream !)

when you compare that Innolux TFT to (C)STN then the difference is already huge. The good thing is, Hantek is running Linux,
so one can really easy insert what so ever display (as long supported by S3C2416). OLED would b for sure great, IPS hmm,
for an AWG for sure good thing but for DSO, maybe bit too slow.

Well I think I might have found one that can be shipped out tomorrow for me. But I do not know at this stage if its worth the money. Maybe I am better off looking at better units that meet their specification?
