Review: Hantek DDS 3X25. Anyone own one?
Mechatrommer:
more test...
yellow=synch out
blue=hantek out
b_o = synch out (notice the glitch)
b_q = square out (multiple at 1mhz, 1.37mhz = out of multiple)
Mechatrommer:
b_r = ramp output at 24&25mhz, 25mhz got in multiple.
b_s = sine output at 30&40mhz, u should already know which is not in multiple.
pls note mhz is megahertz, i lazy to type "shift" key.
Mechatrommer:
b_t = trapezia at 10,12,20 mhz.
pop quiz... which one is in multiple?
Mechatrommer:
conclusion... if you need both synch and out port, really you need to check whether you are in multiple or not before doing your circuit, otherwise you'll lose hair. if you dont understand, ask. if not, dont buy Hantek 3x25 :P
ps: the good news is... this model is obsolete.
saturation:
Are you terminating both the sync and signal output of the 3x25 with 50 ohms, as its needed?
