I could swear you said it was a phase locked loop. I get the feeling you do not seem to know what you are doing.? Am I mistaken? Andy

Good grief, John. Unless your system is really (I mean REALLY) poorly behaved (seriously non-linear frequency vs. control voltage with discontinuities and reversals), a simple proportional control,

UPDATE: My system is a frequency locked loop, by the diagram bellow, I intend to make a plot of a frequency Vs error signal as shown below. Given this plot how would it help me to know the controller

Hello The controller needs to sweep over the area where the resonance is. Its frequency range is 2MHz , what controller specs can I take from this requirement? Also I was told that I need to plot

There have been several comments on high voltage measurements and probes buried in various messages. While fixing my microwave, I needed to measure the high voltage output from the transformer. As

Any indirect link is nefarious. Trust me. They (Amazon) now knows where I got that link, and who you (Sheldon) are, when you looked at the product, what your (and now my) computer model, operating

Note: Most scope FFTs really really, totally, really on steroids suck bilge water. I'd go so far as to say "all affordable oscilloscopes FFTs really suck." Suck to mean "Don't work very well, barely

My older sister had severe asthma, really bad. Mine was bad when I was younger but puberty brought hormonal changes that reduced the asthma attacks from one every week or so to one a month then "I

Hi SD, Dave Jones of EEVLOG did a review on that specific scope. He hated it. The interface was all screwy and he had real difficult time figuring out how to use it. I forget the exact details

And all this time I thought Albuterol was a steroid. A WY LEO with a case of the "lookie loos" rolled up behind me while on side of the road during a drive in company pickup. Asked what I was doing,

Hello Andy ,This driver is being built to be connected to a PI Controller which needs to tune my YIG into the resonance of the resonator. The data about the YIG and the resonance dip properties shown

I do similar stuff. I use a good quality bench scope, and a separate, reliable, HV probe: MICSIG. In my case, devices under test can be, and are, transported to the test bench, where all safety

That's the basic capacitive dropper circuit that Big Clive bumps into in a great many places. Maybe I should have specified operating from a 12VDC source... -- Member of the toughest, meanest,

Yep! My project vehicle is a '78 D200, and the only electronics in it at all are the igniion module (yay! no more points to deal with) and the voltage regulator, which is _not_ built into the

How fast an oscilloscope must I have? I used a DSO rated at 200MHz. I used ~120V [118V RMS], peak voltage 168ish, a 0.5uf [0.503uF] poly capacitor, a 1 ohm resistor to give 1V per amp, the CT-1

And some of those were designed with slide rules and log tables. Now that's primative. Although I still have, and can use, my slide rule and I have my log tables my father used when he studied

Do not think about the problem as 60 Hz. At peak voltage turn on in the USA, you will instantaneously see 150V or so charging the capacitor with very little current limiting. The spike will be
