Kuba, Thanks for sharing this method for reverse engineering. Pretty cool idea! Keith

An alternative these days is to run the debugged OS in a virtual machine, and sniff the transactions as they pass between the guest system and the emulated hardware, or even between the guest system

Hi if the picture shows all the packing then the packing was not correct I now take pictures before opening a package and then use them for the clam The big problem is people selling items on Ebay

Hi, The 8590xE should have? reference input. It is next to the fan on the rear panel and is conected to the reference output by a solid bar type BNC to BNC link. 1PPM frequency meaurement could be a

I'd like to suggest getting one of Leo Bodnar's excellent GPSDOs. I have the 2 output version which I needed to run an SDRplay RSP2 and a VNWA 3E. I bought the outside mount antenna kit from Leo at

Hello together, Thanks for the Information, but I guess I was a little to late for that: And bought another one. unfortunately that one arrived like that: I guess the metal shielding was the problem

I used a FuturePlus FS2000 PCI Analysis Probe with a 16500C and 16700A many years ago for debugging USB host controller driver issues and needed to see what transactions were occurring on the bus.

An ovenized XTAL based or PLL unit at 10Mc should be easy to find. Just Google it. I dont know if any of the new AWGs can hold 1ppm or not. As to testing, my first suggestion that a proper room is the

Cheap NFP are typically not calibrated or accurate. I might have an extra hp NFP system that I could spare… and it is in cal. Locking to a gps would yield decent accuracy usually unless you are way

I have two needs for upcoming projects, at most loosely related to one another. The total knowledge of this group makes me look like a complete neophyte, with only a few decades of experience, so

Aren't these children a bit excessive - maybe we should block both of them. Cummon guys - GROW UP Quoting "Dale H. Cook" <bridgewaterma@...>:

You have not tried to ascertain my professional experience, which exceeds yours by more than a decade, so I consider that reply flaming and shall block your posts. -- Dale H. Cook, GR/HP/Tek

That sounds like the parts were long stored in a very poor environment. I have never seen that in the original caps in any of my 16 HP instruments of that vintage (13 working and 3 parts junkers).

A. My comment is not about your claimed experience. B. It might not work if you do it, but when I, with 30 plus years of experience and NIST traceable gear do it, its dead accurate Its an instrument

Being an EE with manufacturing, parts buying and engineering experience, these caps didn't even make it past check-in against the invoice on Receiving they were that badly oxidised- so badly I could

Anyone know much about these?? ?Allows you to connect a 16700/16900 to a PCI card. I picked up three of them with a used system and was able to get the manual and software from the manufacturer but

Thanks very much Richard.....................................Don. wrote:

Why? How did you determine that the electrolytics needed to be replaced? I have many HP instruments of that vintage that still meet spec and have never needed to have any of their caps replaced,

David Campbell wrote on 3/6/2020 10:14 AM: <snip> Hello, Dave-- Were there any date codes on the Sprague caps? Thirty years ago might register as, for example, 2690 (i.e., the 26th week of 1990).?

651B 1975 edition. Replaced all of the electrolytics and tantalums, quite a chore to get the exactly correct values Several caps were replaced with two or three in parallel. Same or better tolerance
