You may want to look for an old-fashioned Lo-Z probe like a P6056 (500 Ohm) or P6057 (5000 Ohm). Even with their standard BNC connection, they work well with your more modern digital 'scope and can be

Hi Jack, I would recommend thoroughly reading the downloaded document again. Just having a quick look at it just now revealed relevant content at least on page 10 ("Usually, the loading of greatest

that depends on the circuit. Lots of RF circuits are 50 ohms, some 75. However, high speed TTL, ECL, and the like circuits fake being RF (and quite well, since the boards often have to be designed

I have found a similar problem, not with probes, but with circuits. The higher the impedance, the more that the circuit capacitance limits the bandwidth. Most of the 200 Mhz or higher circuits look

Hi All. Thanks for linking for the album - I'll work out how to do that for next time. I've added an annotated photo showing my interpretation of the -5V traces on start-up (

Hi Raymond, Thanks for your ever so prompt response.?? I am not missing the ABC's of probes and in fact have previously read it a few times. Rather than look for my paper copy, I just downloaded it

Hi Jack, The only thing you're missing is a recent edition of Tektronix' obligatory document "ABC of Probes", downloadable from e..g. <https://www.tek.com/document/primer/abcs-probes-primer>. Yes, a

As a result of my recent purchase of a Tek scope with 1 ghz. bandwidth, I have begun looking for probes. I have looked at the specs for a P6243 and a TPP 1000, both rated at 1 ghz bw. Both instruction

I just purchased a TDS 600 series scope which had apparently been rack mounted. Consequently, it is missing the rear cover, handle, bottom feet and kickstand. If someone has rack mounted or has a

Hi Ancel, That is not the same cable as a 012-0482-00 at all. If everyone can be patient for a few hours more I will test both of those Tektronix cables on a 7S12 TDR along with a couple of commercial

Hi Tony, WE ARE THE RIGHT GROUP. The members of this group, as a whole, share a common interest in ANY and ALL TEKTRONIX instruments even though Individual members may only own one Tektronix

I had a 485 that hiccupped when I got it. The way I determined the bad rail was to look at the turn-on and turn-off edges while in hiccup mode. One rail didn't get as (proportionally) high when ON,

If anyone wants to have cables made for them, or buy wire or connectors, consider RF Connection: Rfconnection.com No “s”. Long in the business of making cables for military, government, and

Good luck, the RIFA caps are worth replacing, especially if you're in 240V land. Make sure you replace them with properly specified X or Y class capacitors, as required. You can find plenty of info

The cable I have for the instruments is a Tektronix 012-0057-01, Z0 = 50 Ω, coax cable assy, with connector boots. The engraving on the BNC metal is 'KINGS KC-59-123'

Exactly the right group - wrong topic. Do what the group owner, Dennis, suggests and start a new topic relevant to your problem. Plenty of people who have an interest in, and knowledge of how to fix,

Thank you! I think that is what one of the problems I should do first! Have a great day and weekend! Tony [email protected]> wrote:

I'm very sorry that I emailed the wrong group! I'm little desperate and it shows! I hope your group will forgive me and I'll try not to repeat my mistake! Have a great weekend! Thank you. Tony wrote:

Thank you very much for comprehensive email, that is pointing me to the right direction! It seems to me that the Beam Switch is sticking for sure and could cause most of my problems. I'll try to

Hi Tony, The subject line of a thread tells our 8,000 members around the world whether this is a topic that is relevant to them. In this case the thread is about the SG503 amplitude precision. It
