Re: Tek 495P A54 Memory Board Option Switch Settings for v9.7 Firmware
The documentation is definitely incomplete and downright questionable in places (and that includes the notes on ko4bb.com from various people including myself). If you've found a combination that

Re: When Posting Photos Please include the following...
I'm lazy in the same way most of the time. Also, I was uploading new photos to an existing folder I own on another .io group and had an amazing difficult time. The photos would load but not show up.?

Re: 2215A LVPS repair
Yes, my gut feeling too : from the data I collected previously, basically the worse FET's have about twice the gate charge than desired. So even if the driver circuit had zero headroom to drive that

Re: Compatibility between Series-5000 and TM500/TM5000 latches
Basically, no. TM500 looks identical to 5000 series scope plugin latches. I think they made 5000 series scopes with the same frames and decided to have the same board designs, but different signals

Re: Compatibility between Series-5000 and TM500/TM5000 latches
From what I understand: TM500, two varieties of latching mechanisms, one (I think the earlier one) more prone to breaking than the later one. TM5000, one latch mechanism. I can 3D print these. 7000

Re: Looking for Power Cord for 400-series Scope
The Heyco reference was mine. They make those plastic, snap in strain reliefs. It looks like the original Belden part number was: KH5442-290D I found this by searching the Tektronix part number and

Re: Compatibility between Series-5000 and TM500/TM5000 latches
Actually I was asking about compatibility of 7000 series scope plug-in latches with 5000 series scope plug-ins.? ?Not TM500/5000 series modules.? ?But I can check for myself this evening when I

Re: Looking for Power Cord for 400-series Scope
Back in February of this year, there was a similar thread titled "Replacing power cords..." There were some ideas there, including a source called Heyco (?) Good Luck, Colin.

Re: Compatibility between Series-5000 and TM500/TM5000 latches
Jim, I have a 7623A scope with about 13 plug-ins and a TM503 and TM504 with four plug-ins (and another to come). I can tell you that the latches for the 7000-series and TM500-series are NOT the same.

Re: Compatibility between Series-5000 and TM500/TM5000 latches
Following with interest because I own a 5103N/D10 with two 5A15N and one 5B10N plug-in from which a previous owner removed the latching mechanisms.? Didn't want somebody removing the plug-ins, I

Re: Looking for Power Cord for 400-series Scope
Some of those cords are shielded, which makes them both larger and stiffer. I have hundreds of old IEC C13 cords in storage. Next time I can get to them, I'll see if any have the keeper. Michael A.

Compatibility between Series-5000 and TM500/TM5000 latches
Hi, I know there have been enquiries as to whether the back-plane connections of these two series are compatible, but that is not the question that I am asking. I am wondering if the mechanical

Re: All TekScopes email sent to Spam
Hi Dennis, I am well aware of that, and my email, according to spamhaus, was in the list. And, I know who put it there, because he smugly told me he did it. To get out of the list, spamhaus requires

Re: Looking for Power Cord for 400-series Scope
I've considered cutting an IEC cord (hopefully finding a thinner version since, as you point out, the more common styles are thicker) and just using a common velcro wrap as a "keeper". The clip would

Re: Looking for Power Cord for 400-series Scope
They were quite common at one time. They used a thinner outer jacket to make them more flexible. Some computer power cords are similar, and you could cut off the IEC C13 connector. At one time, I

I prefer to keep the text of discussions and the relevant pictures together, so I create an album on Tekscopes first, then put the pictures in, copy the URL to the album from my browser, and use that
