    I'm a little late to the party here but thanks for making this video. I have been thinking of getting a 2456B or 2467B to supplement my 2465. I know that the RAM backup battery can be an issue with these late model scopes and it's nice to see some of these procedures done.

    Thanks Keith, I really appreciate the effort you’re putting into producing these videos. This was immensely useful for me as I suspected that I needed to perform a Cal 8 on my 2465BCT. After seeing the Cal 8 run-through it’s confirmed that my focusing issues will be readily fixed. 😀 My scope can’t focus both the trace and the edge text at the same time especially with higher sweep rates. At first it looked like noise or jitter on the signal but when I adjusted the trace to crystal clear focus the text on the edges went out of focus.

      You're welcome. There's a little bit of information on these scopes but nothing on calibrating them that I can find, and for good reason, they are real long and a pain in the butt. So I decided to post some of what I've done in this area that I know works. Unfortunately I was not able to correct the fault 04 Calibration Constants missing. I just didn't have enough experience in doing the calibration on these, & the instructions were kinda vague if you didn't have the called out equipment. I did video the whole calibration process but I could never get past CAL 09 so I didn't post them. Maybe some day I'll post them anyways in hopes someone can tell me what I did wrong, LOL.
      My advice on the Calibration Modes is don't start a Mode until you either have someone who has done them successfully or has the correct equipment and are willing to screw up the scope if you fail at it. You can enter the CAL Mode access screen but just don't start an individual mode unless your'e prepared to do it. Hope that helps you out. Thanks for the comment. Best Wishes & Blessings.

    I have this same scope. What probes do you recommend for it? Is there a good set of aftermarket probes for it?

    • @keithnoneya
      @keithnoneya  3 роки тому

      It really depends on what you plan to measure with the probe.
      - Probes come in a variety of specifications that measure anything from Frequency, Voltage, Current and even High RF, provided the scope can measure it with the right probe.
      - Each scope has a list of probe accessories intended for the each scope when it was manufactured. You can usually find the list or recommended probes in the scopes Accessories section of the User Manual.
      - The probe selection will depend on: Voltage, Frequency and the amount of Isolation you want for the front end (Channel Input Circuits) for the scope. For this scope Accessories, it's in Chapter 7 on page 7-3 or pdf pg. 173.
      If you don't have the Operator Man you can download it here: w140.com/tekwiki/images/2/25/070-6860-00.pdf
      - You can get an overview of scope probes and what they can measure by looking up each probes Op or Service manual. Type in the probe P number and add pdf to the end and do the search;
      Try this website as a starting place to find the OpMan and probe you may want: download.tek.com/document/02_ABCs-of-Probes-Primer.pdf
      - To answer your second question, yes there are many aftermarket probes that will work on you scope. The trick is to find one that will work with the scope for the application you want to use it for.
      - For a beginner or someone who doesn't have a good understanding of probes, just start with your basic TekProbe™ Level 2 BNC P6136
      10X Passive Probe. It's a good all around probe and the 10X will help protect your scopes front end. But read the document, it should give you a ton of options you never knew you had. You can download the Probe Manual here: download.tek.com/manual/070602504.pdf
      - Hope that points you in the right direction in answering your question for what probe to use.

      Hi Typhoon, Yep I know what you mean, you just have to go through the CAL 08 a few times to get the hang of it and tweak out the problem. A lot of times it's kind of a trade off on which one you want to be more in focus. Hope that helps. Best Wishes & Blessings. Keith Noneya

      Hi Marcos, I assume you mean the TEST 04 FAIL 02 on the screen when I powered up the O-scope. Unfortunately I didn't have enough time to try and calibrate it again. I just didn't have the experience or the equipment to get passed CAL 09. I could get all the way up to and through CAL 09 but when it completed the last step on CAL 09 it said that it failed. So I'm not sure what I was doing wrong and the scope wasn't worth the money in time at work to fix it. You may try asking The Tech Genie on his video here; ua-cam.com/video/BMBrM4OUYGs/v-deo.html. He has repaired and calibrated a few of these scopes. I wish I could have helped you on that one, but I just couldn't figure it out with the time and equipment available to me at the time.

Someone will know where to get one or even my have one. You can also contcat ArtekMedia on eBay. Doing a search ArtekMedia on eBay is pretty fruitless so try this link directly to his eBay store. He collects, copies and sells high quality PDF copies of them. He also give you an option for both a disc and a direct download link so you can get it right now if you want. Here's a link to his store: www.ebay.com/str/artekmedia I would drop him a question on the dms version and see if he has it. hope that helps. I'll look around the shop and see if we or the calibration lab next door has a copy of it. Keith

I've demo my fixed scope in my electronics group and tonight I'm taking it to a larger group where we do everything from electronics, arduino, Raspberry.... 3D printers .... One never knows what we do there or what will show up. Even once a snake show by our member..... It is fascinating that some of these old scopes are functional in these days. I also have couple older so called scopes: PS 148 5" wide band oscilloscope and vectroscope - it is completely dead, but I want to fix it in near future. I have the original Sencore Service Manual, I plan to upload it - where should I upload it? My second other old scope is Simpson Handiscope - no manual or documentation. It "works", but I do not know how well, since I do not understand it much. I also would like to learn how to use it and see if it needs some new parts or not, but I do have everything working and the CRT works also.

      Not familiar with the other scopes you mentioned, they are fun to collect, I have a few myself. You should be able to find what the CTT option does by looking in your user or operator manual.
      As far as who to submit the manual to, I would do two things.
      1. Submit it to B.A.M.A (The Boat Anchor Manual Archive). Here's the link to his page; bama.edebris.com/manuals/, go to the bottom and he has a place for you to; "Submitting a Manual".
      2. I would also contact ArtekMedia. If you have a manual he doesn't have you can send it to him. He'll copy it and send a digital copy of it back to you with the original paper one you sent him.
      Hope that helps get you going in the right direction. Best Wishes & Blessings. Keith Noneya

    what is the use of this machine?

    • @keithnoneya
      @keithnoneya  5 років тому +3

      It's called an Oscilloscope. It is used to visually observe electrical pulses in a electrical circuit. The scope, short for oscilloscope, has what's called a probe. The probe is connected to an electrical circuit that you wish to observe what the electrons are doing in that circuit. Since we can't actually see electricity flow with our own eyes this machine uses a beam of light that scans from left to right on the video screen. Vertically the middle of the screen is usually set at 0 volts and as the flow of electrons increase in current flow in one direction, which it is represented by voltage, the line will go up. As the current & voltage decreases or reverses direction the line on the screen will go down. The rate at which the current goes up and down per second is called frequency. The thumbnail for this video shows me observing a voltage current change at 50 million times a second or 50 mhz.
      The oscilloscope is primarily used to test, align or in the repair of electronic equipment. It can be used to measure the power and frequency of electronic circuits. One of the cool things it does is observe digital signals and in some cases is even connected to circuits to observe voice or music. Some people who are deaf can even use it to learn to speak by watching how their voice sounds using the light patterns on the screen. I hope I was able to answer your question. The question itself was easy, the answer however is quite complex. The Oscilloscope is one of the 20th Centuries most important diagnostic inventions for electronic design and repair. Without it we may not have had computers or cell phones. Feel free to ask more questions. Thanks for watching. Best Wishes & Blessings. Keith Noneya

      Sorry for the late reply, I thought I had answered all your questions until I saw this one. Is the problem you're having the control panel flickering? It's most likely a bad connection or a struck switch. Go find that manual I gave a link to. Go to page 6-10 and start reading from "Diagnostic Routines. Pay attention to table 6-4 for the Test Number and Error code, in example "Fault 02 31" on the bottom of the CRT screen is "CHANNEL 1 VERTICAL MODE SWITCH" is stuck. Be very careful not try and do the calibration procedures with out the proper equipment or you'll screw up the calibration data files and make the scopes accuracy invalid. You should probably make a video of what the scope is doing wrong and them post it on UA-cam and ask for help. When you get it posted let me know here with a link and I'll go look at it.
