HP Agilent 54510a Oscilloscope Help

Hello,

I recently picked up an HP Agilent 54510 Oscilloscope on eBay for parts/repair. The problem stated with it was that I would not power on. Upon receiving it today and plugging it in, you could hear it power up and the fan run, however it had no display. Upon removing the top cover and checking the HV board, I noticed there was a blown 2A fuse. Upon replacing the fuse it comes up and now displays fine, however when I try and bring up the menus they come up fine, but I am unable to use or get any of the selection buttons (the vertical row of buttons along the screen) to select anything in any of the menus. I was just curious if anyone knew of anything to try before I dive into this more? Maybe some one has seen that problem before with their 54510a or similar scope? Thanks!

Regards,

Brandon

I'm not sure what you are referring to.

The buttons down the left side of the screen are draggable icons. If you, for instance, want to measure rise time, you drag the rise time icon out onto the screen, onto a waveform, and the measurement is set up for you.

Is this what you were asking for?

Al,

I believe you are thinking about the 54810A (windows-based Infiniium). The 54510A is the "old" scope with only push-buttons on the right side of the display. I remember it fondly because we introduced when I worked in Colorado Springs (~1990). Do you have any service knowledge on the 54510A?

Brandon,

I worked on these scopes but been about 20 years since took one apart. The problem could be software or hardware, but I'm leaning toward the hardware. There's a front panel housing which has the elastomeric keypad, RPG knob, panel connections. I'd take it apart and check all the connections.

The service manual is available here (warning 27MB file): http://cp.literature.agilent.com/litweb/pdf/54510-90903.pdf . It mentions a keyboard self-test on page 6-18 and walks you through the troubleshooting diagram.

Hope this helps!

Mea culpa, mea culpa, mea maxima culpa (sorry, but I grew up in the Catholic church, when Latin was still in use).

I can't remember the last time I even saw a 54510. That was around when I was still messing around in compiler and emulator land, before I became a scope ****. I bow to Mr. Kawasaki's knowledge.
