    Tektronix vrs Fluke Scopes?

    A local recycler has several scopes available. It's reached the point where I should get something more reliable than my old Heathkit. The buyer will be given the opportunity to see the unit in operation, but there is no warranty.

    The choices are a Tektronix 2230, several Fluke Combiscopes, Models PM3380A, PM3382A, PM3380B. Any suggestions?

    He's also on Ebay. Those Flukes have been up for a while.

    I'd go with the DSO Tektronix.

    Got a battery operated sig gen you can take to test it?

      If you don't have that bring a tiny AC output wall wart at least you'll see if it can display a sine wave.

      The transformer is for isolation.

        Good ideas. Somewhere I have a Heathkit scope calibrator, which would also serve the same purpose.

        Actually, I may be getting ahead of myself. I picked up a Tektronix 466 a couple of years ago at a GSA auction. IIRC, this is an analog storage scope. It functions as a converntional scope, but I haven't had a lot of luck with storage mode. Which raises the question - do I really need a storage scope?

        But Honey, it's so cool!!!!

          I'm happy with my Tektronix 475 plentiful and cheap no digital storage.

          If I wanted that I'd rig up an old pc and buy one of those oscilliscope cards.

          Sure digital storage is cool but how often will you use it?

            Each type has it's own advantage. I started off building a Heathkit IO-4550 about 30 years ago. It beat the heck out of borrowing a scope from work, but it had stability problems. I fixed a lot of TVs with that scope. Other than drifting as it warmed up, it also took up a lot of bench space. It's 0-10 Mhz frequency response limited it's usefulness with digital troubleshooting, so about 10 years ago I picked up a used H-P 1220A. It was about half the length of the Heathkit, weighed half as much, and was steady as a rock. That died about 7 years ago at a time when I had about stopped working on electronics.

            About three years ago I bought a Tektronix 765 (with camera) and the 766 at a GSA auction for about $35 for the pair. My son got the 765, I kept the 766. There are times where it is helpful to know what happened BEFORE the trigger event, or to be able to see a single event clearly.

            I've looked into the various USB scopes, but they have the same disadvantage at the IO-4550 and the Tek 466 - by the time you add up the space taken by the usb scope and the computer, you've lost a significant amount of space on the workbench.

            Of course, the bottom line is the most antiquated, unstable, low bandwidth scope beats the dickens out of guessing if the DVM is showing a steady voltage, or something with a lot of ripple, noise, or other undesirable characteristics.

              Fluke 123 no image on the screen
              by Khoja
              Hello experts,

              I recently purchased a used Fluke 123 Industrial Scopemeter from an online Japanese auction site (jauce.com). It has now been delivered. Unfortunately, I overlooked the fact that the seller neither guarantees its working condition nor accepts returns.

              When I power it on, the backlight comes on, but there is no image on the screen. After opening the device, I noticed clear signs of previous soldering in several areas (photos attached). It seems someone attempted repairs before.

              At this point, I'll have to try and fix it myself. Has anyone here...

              repairing a Fluke 335 clamp meter
              by Baldbentley
              I am repairing a Fluke 335 clamp meter. After contacting fluke it appears there is no service manual or circuit board/ component list available. I have determined that there us a faulty PNP bipolar junction transistors shown in the pictures. I am having trouble sourcing this transistor. I pulled a good one off of the board and tested it with my component analyzer but I cannot find anything that matches the specifications. Any help locating this part or a replacement would be greatly appreciated.

              Thanks...

              Buy a Agilent U1242A or Fluke 179 DMM?
              by Crystaleyes
              Need a new (used) DMM and there are two in the area for resonable prices.

              The Agilent U1242A is 63 GBP (about 80 USD)
              https://cdn.badcaps-static.com/pdfs/...4dc89c13fc.pdf

              The Fluke 179 is 55 GBP (roughly $68.00)
              https://www.fluke.com/en-us/product/...fluke-179-eda2


              Kinda leaning towards the Agilent.

              Anyone think that is a bad idea?

              Anyone know how to take apart a Fluke T100 Voltage Tester without damaging it?
              by cheeky2
              See attached picture. I have a Fluke T100 Voltage Tester that the resistance and diode measurement isn't working (it's not the batteries (as I have already checked them and put decent Duracell 1.5V AAA batteries inside it).
              I have looked on the web for any information and on youtube without any results for this model.
              There are no screws visible or anything obvious. So I am hoping someone here has the solution to take it apart?
              The only way I can see is underneath the yellow rubber handle area, however I don't wish to damage it if it isn't the case!...

              Tektronix 422 with No Power
              by KYBOSH
              Picked up a Tektronix type 422 oscilloscope locally for a few bucks last year.
              It wouldnt power on at all so I stowed it away under my bench for later testing.
              Today I remembered it was down there and pulled it out to see what was what.

              I checked for continuity and everything checked out.
              There was a burned smell and a resistor was replaced with a temporary replacement (see yellow box in picture).
              The burned smell is very pungent/acidic and I am not familiar with these vintage electronics to know whether I am smelling the remains of the replaced resistor or...
