AFG1062 outputs waveforms in burst mode when rotating the knob

Post by norbrunner » August 25th, 2017, 8:08 am

Hi,
We are using the AFG1062 with version V 1.0.4. When changing e. g. the frequency via the general purpose knob in burst mode, two sequences of the chosen waveforms are outputted at a certain frequency (by the way, this two pulses destroys my circuit :cry: ). Is this normal or is it possible to deactivate this or is it a bug?
Thanks
Norb

Could you post your setup file so I can take a look?

Hi Bryan,

here it is. I changed it into ".rtf" because of file transfer convention.

Hi Norb,

Sorry to hear about this blowing up your circuit, it's definitely unintended behavior. My hunch is that there is some sort of switch bounce causing the buffer to output (but that's just speculation). I'm going to document this and pass it to our product line team. I'll be sure to update you when a firmware update is available!
