These may not be as much fun for RF experimentation as you might think. The whole point of this unit is to implement the filters and responses required for CISPR conducted and radiated

Hi Graeme, I've just looked through the shack and, unfortunately, I cannot find the attenuator.? As I mentioned, it's been years since I last saw it, so I probably took it to some long-forgotten

A few comments... 1. "Svclo Ctnuo." abbreviation for "Servicio Continuo" which would translate into? "Continuous Service" 2. "Cos. P" (0188) Cosine Phi, or Power Factor, is 0.88 I wonder if the

Ed, IMHO you have an A.C. motor with a power factor (cos "fi") of 0.88. Regards, Antonio/CT1TE. - 2018-11-27 10:54, Ed Breya via Groups.Io escreveu: Links: ------ [1]

One more thing - the "(0188)" could be 188 watts output rating, which would be 1/4 HP, a nice round number. Ed

Yup, that would do it. I have the relay one-shot circuit working now, and installed in the TG. It works just fine, and I'm not worried about turning the knob too fast anymore - it's actually pretty

A little more info would help - especially a picture. How big is this motor, in terms of physical size and estimated output rating? How many actual leads does it have? Is there a built-in start

Hi Dave It sounds like you have a stepper motor 73 George G6HIG

I have a Spanish-made motor that I need a second opinion on.? On the spec plate, one line states the following: "Cos. P" (0188) "Svclo Ctnuo." The 0188 is in a box between the other items.? I think

Hi Ed, When I needed to drive a newer 15V?HP 3321Sx attenuator I used a PIC to read the switch and drive the coils (via OC drivers of course). This allowed the coils to be set when the switch had

Thanks Bob, My circuit is a little different from yours. Mine uses a full wave? rectifier with a center tapped transformer secondary. I will get a 30V center tapped transformer locally and replace

I repaired a crystal option on an HP 3325A.? Usually they run high at room temperature.? As they heat up the frequency gets lower to within a couple of hertz of 10MHz.? At that point it can be

Not the extender cards. I do have some extra NOS 5328A extender cards that can be made available. The test cards are used in place of the function selector. You pull the function selector and use

Hi Glenn!! Are talking about the extender cards for working on the counter??

So far, so good. It passed the hairdryer test, and has been running fine continuously since yesterday. Ed

I use the 35665A almost daily in the lab, for quick checks of gain and frequency response on various devices. Recently channel 2 has started to act as though it is stuck in "DC" mode, or at least it

Leo While I respect your not wanting to spend time on the drawings...without them the value of your work is interesting but nearly useless to most of the rest us. Things that will help the rest of

LeoHappy either way, I would buy one off you if you made one but if don't want to spend the time, I can put together a PCB. However my design would have to go through PCB Wing in China and would
