Start with the power supply fuse, then the switch. In my 16500B. you draw a little power regardless (IIRC). You might check for that. Does seem to be the power supply.

hi guys i am new to electronics and need some advice. first my tale of woe....i wont bore you with all the details but basicaly i was stupid and brought privately a hp16500c, i drove 250 miles to pick

I love this ebay comment: Condition: Used: An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a

Hmmm.... then burned, thrown in a canal, left to soak for five years, and cleaned with the garden hose? ;-) Some inox screw may still be good, and considering the price of HP screws those days on

Hi all---- http://www.ebay.com/itm/S165-HP-SPECTRUM-ANALYZER-8591E-/140600806917?pt=BI_Analyzers&hash=item20bc760e05 Jonathan

Agreed. Self-contained in the unit itself is best as well. You will need at least a set of two 10 bit converters for X and Y and a lesser resolution but similar speed converter for Z modulation.

My understanding of SA's is that their displays are not fast. There is no advantage is sweeping too fast and a lot of disadvantages. I can't imaging needing more than 100KHz of bandwidth on the X and

Kuba, I have an HP 8568B at the moment and would like to see something like you describe developed for it, and for the 8566B too, which I hope to acquire soon. The output specs are widely available

Personally, I like the no-PC approach. Don't have to worry about hard drives failing, reinstalling long-obsolete operating systems, etc. I like a piece of hardware (with embedded software)!

The question is: are those fast enough to be used to replace what was inside the box of various otherwise useful HP instruments. I'm also more than willing to have potentially extra functionality

There will be a frame buffer, that's not a problem, and a video DAC as an option -- it's one chip these days, not expensive either. PC is of course cheap, but you may not wish to use one -- this is

Hi there, I recently acquired an e6380a w/ option 1d5 for use on a local ham repeater project with the santa cruz amateur radio club. the unit passes all internal tests (service4 rom module) but i am

If you go with VGA, DVI, HDMI or any other pseudo video interface they you must include a video frame buffer, video speed D/A converters and the logic to support it. Even though LCD screens include a

I don't think that audio frequencies are anywhere near what is needed for most instruments. To maintain accurate display I'm thinking of at least 1MHz bandwidth -- that means 5 to 10 Ms/s sampling

This is fine and dandy, but for real instruments you need VectorVGA Pro, and it looks like it's neither designed to be affordable, nor was their NRE "cheap". Once you decide to use an FPGA (like they

That's "almost" what we want, but not exactly. It has a fixed 800x600 resolution, and it will look like crap on widescreen monitors. For some reason everyone must be watching movies on their monitors,

Haha. 240Hz sampling rate at 10 bits.

I'm thinking of something where you plug it in and it works, with or without a PC. I don't think *that's* available. Kuba
