Password Change, and Scope looses link

I am using a password e-mailed to me to log in. How, stroke by stroke, can I change it to something I can remember? My 3205B scope looses it's USB link after a while, and I have to reboot the computer before I can bring it up again. The pilot light is always red. On a four channel PicoScope, I have ...

Need to enter a file from math scope trace into arb

I need to enter a file, generated in the math function of scope, as the arbitrary waveform, to be generated at the output BNC of the generator in my scope. I have a PR-3205B bought in January 015. Is this within the normal functioning of the scope? If so, I need step-by-step instructions. If it requ...

Sope screen goes blank, and "check USB" message appears

I am running a brand new HP4545 computer, and this happens every time now. I think that the computer terminates the USB port link. If I switch USB ports, while running, it will recover till it gets lots of large waveforms, then it trips off again. The computer doesn't give me any error message, exce...

Signal Generator to use a stored Scope File Waveform?

It would be very useful to me in my present assignment, [Faraday Cup Instrument of Solar Probe Plus] if I could cause the analog ouput of the signal generator channel of my scope to trace a stored waveform, earlier recorded on a PicoScope channel. Is this possible? If not, is it reasonable that some...

XY Display Uses

I am an Analog Design Engineer. I intend to construct, for my own use, a transistor curve tracer, and a magnetic analyzer, using Pico scopes. I am comfortable with the analog circuitry to power the drive from the Pico signal generator, and present outputs at a level usable by the scope. I could use ...

Re: Intro and a question

Thanks for the quick answer, Alan, I just tried it and it works fine. I measured the self resonant frequency of a bank of six transformers, as zero phase shift point, where the Lissajous pattern is a straight line. I was going to ask how I should have known, but I found the users manual under Help. ...

Intro and a question

Hello, I'm Newton E. [Newt] Ball. I'm an 84 year old engineer, and inventor. Among my specialties are energy conversion, and switching power circuits. I am in the act of checking out a new circuit at [SSL] Space Sciences Lab, UC Berkeley. The circuit drives the grid of the Faraday cup experiment, on...
