Hi Simon, As far as I know the 11801C is the last of the 11000 Series and produced from the end of 1998 up to and including 2000. Really no need to replace the Batteries in such a hurry (if there

PS: May be broken I|O buffers on the card. Try to communicate with oscilloscope with any other software first. I used Win 98 SE. Anything like old Labview under Windows... And FAS under DOS section.

Your GPIB card does not see your o'scope: DUT — Device Under Test May be your settings for oscilloscope's GPIB address are wrong. May be your cable is broken. Did you connect o'scope before via

Thanks Patrick. I'll take a look at them.

I'll tell you the units that I currently own, I would recommend any of these models depending upon your intended use: HP 8642B, 100 kHz to 2.1 GHz, extremely high quality signals produced. Perfect

Thanks, Magnus! The additional advice is appreciated. I bought it for a January project (looks like a slow month for me), so I'll be taking my time to do as you suggest. I've already ordered the

Thanks for the info Patrick. So what about a signal generator?

HP 3325A is a good synthesized function generator, with highly stable frequency. Sine wave production to 20 MHz; square wave production to 10 MHz. Triangle and tooth waveforms to 10 kHz. Tek FG

So does anyone have a good recommendation for a used function generator? I have been searching for a signal generator and have been saving my pennies for one, but I think a function generator may

Thanks David. I suspected as such, but I never really knew for sure. Thanks for clearing up the compensation question for me.

Thanks Albert. I will move the images to an album so others can perhaps benefit from my recent troubles. [Non-text portions of this message have been removed]

I feel as though I've begun down a path that is going to be quite fulfilling. Thanks again Jim and all the others who helped me out over the past week. You guys are a rare breed, and I appreciate the

Thanks Siggi. It really is a good feeling. I really feel the support and goodwill from this group. As to the soldering iron question. I have a weller temperature controlled station. I'm not sure why

the sloppy solder job. I had some trouble getting the original zener out of the board. Do you have a decent temp-controlled solder station? I used one of those horrid $20-or-so cheap-ass jobs

that’s how we do things….get each other in trouble. welcome to our world…… yes your generator will do… can you measure it’s frequency… that’s what matters on the horz cal. enjoy

Just a remark about pictures Kevin. These usually go into an album in the Photos section. That makes (over)viewing quicker. Probe alligator clip connected to GND somewhere or left open shouldn't make

The probe ground and calibrator ground are the same so the probe's ground clip does not need to be attached and that is why Tektronix did not provide a spot to attach it. In theory connecting the

When you get down the list to the non-urgent parts, DigiKey offers free shipping on orders that come in the postal mail with a check as payment. That way, you can get several penny parts arriving at

Thanks David. I may revisit the calibration techniques at a later date. I fear I'm tempting fate to get into the scope again...

No worries Ed. You have aided in my electronics education. Now, I just need to figure out how to really use this thing. Here is another dumb question, but since I have the ear of the experts, here it
