Hi all, I came across a 693B sweep oscillator that's in pretty nice shape considering it's age. It seems to be fully functional, tunes accurately, etc. Front panel mechanicals seem to be in good

S-parameter test sets don't have anything to do with active vs. passive. First thing's first, please read up on S ("scattering") parameters a bit, as I'm typing on my phone and explaining it would be

It's an HP 8754A. And I have a suitable phase-matched splitter (one in, three out). I was under the impression S parameter test sets were only needed for testing active devices under power. This is

Ack, sorry a directional coupler. But best to find an appropriate S-parameter test set for your VNA. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Is this an 8505A? 8753? You need either a good splitter or (better) an S-parameter test set. THEN connect to port one. :) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

I don't have a "port one". I've got one RF out and 3 inputs, R, A & B. That's all.

It's simplicity in itself: just connect it to port one, and measure S11. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Hi all, I can't find any info on how to connect a VNA for testing dummy loads. All the set-ups I'm seeing are for thru-line measurements for DUTs like filters which of course have input and output

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
