BER measurements on the BA1500 have a minimum frequency of 100Kb/s, so yes this tester can go that slow. However the Auto-optimize eye and Physical-layer tests have a minimum frequency of 70Mb/s.

Good news Norb! The new firmware is up: https://www.tek.com/signal-generator/af ... lease-v105

Are you using an Administrator Windows user account on your DSA8300 and has UAC been disabled?

IIRC, from OS restore, UAC is disabled on real-time scopes. The DSA8300 might not have this disabled by default.

Many commands don't affect *OPC? and there are many of the scopes systems run asynchronously, which leaves us with cases like this one where the only sure way to synchronize is to use single shot acquisitions.

Hi ellen, What's your end goal in this case? Therecould be a number of things (including synchronization problem) that could be at play here, but it is worth noting that polling the instrument whilst running isn't best practice. I'd recommend single shot acquiring however many acq's you'd like to he...

Hi Steven,

I'll see if I can re-create this, what you're experiencing is pretty odd. We're running the latest firmware though (https://www.tek.com/oscilloscope/dsa830 ... ws-7-v6511) so you may try upgrading first and see if the problem persists.

Hi Tobias and Norb,

I'd like to collect some more info on this, please contact us at [email protected] with your contact info and put to the attention of me (Bryan).

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...

Could you clarify what you mean by "all the others"? Are you outputting on multiple channels and the channel with your pulse arbitrary function won't output when manually triggered?

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