Re: Faulty signal generator on 5244B

I have the system running with the v 1.1.1.4 driver now. All the 43ms drop-outs in the AWG output have disappeared !!! Unfortunately... when the AWG is the signal source for a RF resonant circuit with 400kVAr in the reactive components, whenever the AWG frequency is changed (to track resonance) ther...

Re: Faulty signal generator on 5244B

Downloaded the Beta software - it seems to be 100MB smaller than the current 6.8.11.20 ??? It can't see my 2206 scope and will only run in demo mode. Tried it with a 2204A and it does run that, but the 2204A AWG is only 100kHz and we need 1MHz. I sent you a message on support@picotech.com - Please c...

Re: Faulty signal generator on 5244B

That is really good news! You've no idea how much hassle this has caused - mostly with problems sourcing a replacement USB controlled sig-gen. Current driver is 1.1.0.143 - please remind me how to upgrade to the latest version, I seem to have lost the ability to do this... Must try this ASAP ! Thanks

Re: Faulty signal generator on 5244B

Hi Guys, This sounds very much like a problem I had with a 2206 AWG last year. The (squarewave) output would go and sit on the rail for the region of 43ms whenever any scope setting changed and sometimes apparently at random for no reason. I would be very interested if this was fixed now for the 220...

Re: AWG Phase Jumps

Sent a bunch of traces and a couple of follow-up Emails? No resonse. Did you receive them OK?

Re: AWG Phase Jumps

Thanks for the reply... Unfortunately, it's soooo much worse than I first realised! I bought a second 2206 to find out what the AWG in the first one was doing ('stuff' only happens between sweeps). Every few seconds, the AWG output goes and sits on the rail (either) for around 42.5ms :shock: at rand...

AWG Phase Jumps

I have a 2206. I use a square-wave output to a driver circuit, and from there to a high 'Q' resonant circuit. The scope also looks at the high voltage from the resonant circuit, via a divider. Whenever anything is changed e.g. voltage scale or output frequency, there is a step change in phase to the...
