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

<< < (7/134) > >>

Mine should be here in 2-3 weeks; if no one has posted detailed waveform + accuracy measurements by then, I will do so (before I "adjust it" and after).

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 ... :-//

I tried to connect one  channel  set to the max frequency (100Mhz Sine) to the HF counter directly on the PCB and guess what... it worked! It seems that everything, except the jack, is already on board for the HF counter to work  :-DD

Neat.  I will further test that when I get my hardware. I have a 2.1GHz signal generator that should give it a bit of a workout ;)

Well, I got my unit today, and I must say I am rather impressed in general by it!  The shipping was reasonable from the seller I bought from on EBay, and it tool only 4 days (shipped last Thursday, got it today) via DHL.

I still need to take it apart and see what's inside!

nctnico:
Anyone played with the digital outputs yet? Does the PC software have a special 'digital pattern' mode? It would be nice if it could produce I2C and SPI patterns with a tool.
