Jinxie, I should return to the lab in a few weeks. Can crank up my HP 4195A network -Spectrum analyzer (500 MHz) Also the Boonton / Measurements GDO and Q meter With a photo and specs of the coils you

OK..... quite a lot to digest there and it's rather late at night in my zone right now so I'll have to re-read this in the stark light of morning. I think it would be illustrative to post a photo of

Modern laser printers and copiers use a finely powdered plastic toner to create the letters and pictures that are on the page. The plastic dust is placed onto the paper electrostatically, and is fused

Don't get too enamored with tracing out and debugging your power supply, 9 times out of 10, the problem will be simply a case of bad electrolytic capacitors. I am not being casual with my statistics,

Note that the 6cm diameter loop antenna ideally needs to form a closed loop, so one end of the loop connects to the centre pin of the coaxial connector and the other end of the loop connects to the

If it helps, I dug out one of my test solenoids and put a 390pF ATC 800B cap across it and used the loop antenna method to find the resonance with the VNA set to s11. See the image below where the

Marco, For A1-A5 and G1 to G3: +0.019V/ 1=+4.8V For G4 to G6: -7.4V / +14.28V With my 8595E, A5 -16dB is activated with CORR=ON, and OFF when CORR=OFF. This would mean that I would probably have a

I have a 8595E that I want to remove the CT2 Demodulator (option 110) card from. Now I am wondering if any rewiring is required? I tried to find the option 110 installation instructions, but sofar no

Yves, I finally had some time to solder and to the measurements, sorry for the hold up. Below are the results ** Next I checked all the lines to see if they would ever change by changing the ref level

Greetings, I asked a longtime friend who spent his career in the printing and photo lithography industry. He suggested reaching out to the “American Academy of Forensic Sciences” located in

Hi saevar, I saw them but these are labeled as for 8340B not 8341B. Do you know whether firmware for 8340B and 8341B is exactly the same? Regards

Yes, and also the ferrite can introduce non-linear artefacts at levels below saturation. This type of distortion can happen if you use the ferrite in a narrow bandpass filter for example. Note that

I read in your links to the threads...that ISO...which I paraphrase here... they think "if there is transfer, and sticking, it is likely toner." AFAIK, that... if I have articulated their claim

Check the double tuned LC network theory. As you change the coupling between two tuned ckts, they interact, and the usual resonant peak becomes split. In a GDO your exciting the LC DUT with the GDO

If they were stacked...heat, pressure, and time. > > >

An isolation transformer is always a good idea when working on mains-connected circuits. If nothing else, a couple of regular transformers connected in cascade with the second "primary" being the

Wikipedia provides the answer. The name was "Trixie", not Jinxie... :-) -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a

Due to core saturation?

You say the GDO must be loosely coupled, which does make sense I can see now. However, that's another aspect of my method which was wrong, then. I was inserting the probe coil actually inside the test

Differential probe isn't going to keep *you* safe...... The isolation transformer might. (And most variac's are NOT isolation transformers) <anotherlin@...> wrote:
