Can my Rigol dg1022Z counter be defective ?

<< < (3/4) > >>

Njk:
Anyway for DG800 I witnessed it's working somehow. Perhaps there can be variations from one sample to the other.

bd139:
It'll work for a bit untily you accidentally exceed the miniscule voltage it'll handle before dying  :-DD

Njk:
Well, there is some protection in the form of clamping diodes. Although the input range is quite limited indeed and generally it's not a unique instrument in that regard. As usual, RTFM before use.

Edit -> I misread the title. I thought it was talking about the later DG1022Z.

Yes sorry it's dg1022Z

The running title changes from post #10 onward, oddly enough….

Okay, tried out mine last night and and the counter seems to be very level sensitive. Started off with 10V p/p sine wave and the counter sat at zero. At 2V it was a bit jumpy and wouldn’t go above 1.3MHz. At 1V p/p it worked great all the way to 25MHz. Input clamping diodes were mentioned. I’ll put the scope on it and see if that is happening.

Yes I corrected the title :p

Do you remember the trigger sense and trigger level it was set ?

Ok thanks, let me know!
