Description: Tektronix 2465B Calibration Series: Pre-Calibration DAC Adjustment Video. My Serial Number is below B04999 so I will be doing the procedure for that. The B05000 may be the same I didn't check.
Prior to doing the Calibration on the 2465B the Service Manual asks you do some Pre-Calibration Adjustments. Here’s one the them; setting the DAC Reference Voltage.
If you have not done the LVPS voltage checks and set the +5vdc reference I suggest you do that now: Here’s the link for that video: youtube.com/edit?o=U&video_id=lnguy8ELSP0
Just a quick Cautionary Note: The Calibration Adjustments is very long, laborious and should not be attempted if you don’t have the equipment and if you are not familiar with repairing electronic equipment. The oscilloscope may have lethal voltages present when the outer cover on the oscilloscope is removed. So, if you attempt this procedure you do so at your own risk and with the understanding you know what you are doing and are willing to accept those risks.
Note: Some of the pages may differ depending on what serial number your scope is or version of the PDF you have. If you need a copy of the 2465B you can do an internet search and download one. If you want a quality CD hard copy You can buy one from Artekmedia for around $14.00 bucks. It’s well worth it, they do an awesome job on all their manuals. Nope I don’t get a commission for referring them.
- I’ll be using the 2465B & 2467B Tektronix Service Manual P/N: 070-6863-01 pages 5-3, and approximately pdf page 455 & 456 for R2010 the +5vdc DAC Ref Voltage adjustment and test point.
I am by no means an expert with the repair or the manual of this scope. However, since I couldn’t find the information without spending hours looking for it I decided to compile some of the information in one spot. This is just what I’ve learned so far and wanted to try and help. I hope this helps someone just starting out with these scopes.
If you learned something from my video and appreciate the effort to film it, edit it and post it, please give it a thumbs up. If you would like to help my channel please subscribe to it.
If you would like to add or correct some of the information please comment, or send me a personal message using the “about” tab on my home page.
Thanks for watching. Best Wishes n Blessings. Keith
