Hello 
I have new the zerooscill. and have very hard problems with tracking
and stabality of the tuning. I made also the 1V/per Okt. calibration
but there is no chance to do this when the tuning is such unstable. It
sounds like the frequ. is modulated from a s&h ore something.

I just got it from maybe 3weeks from analog haven.

Does anybody know what is to do?

Please send it back to us and we will recalibrate it for you.
Thank you.

Cynthia

Ok, i  will send it back to you...I don't know if i got a bad one but
there have been scratchs on frontplate too.
At this point i wanted to ask, if it's normal that the square wave
only goes to 20% and then break up?

Hi Cyrill!

 

The "square wave" output is actually 

An adjustable Pulse wave, and the 

PWM knob on the far right controls

The duty cycle..

 

Please let us not bother everyone 

with this conversation and contact

 me in private email on such matters.

I will give you the shjpping address 

And we'll have a look!

 

Best Wishes!
